AllianzGI Income & Growth Fund

Investment Objective

The Fund seeks total return comprised of current income, current gains and capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees AllianzGI Income & Growth Fund		Class A	Class C	Class R
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)		5.50%	none	none
Maximum Contingent Deferred Sales Charge (CDSC) (Load) (as a percentage of the lower of original purchase price or NAV)	[1]	1.00%	1.00%	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI Income & Growth Fund	Class A	Class C	Class R
Management Fees	1.05%	1.05%	1.05%
Distribution and/or Service (12b-1) Fees	0.25%	1.00%	0.50%
Other Expenses	0.01%	0.01%	0.01%
Total Annual Fund Operating Expenses	1.31%	2.06%	1.56%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Example: Assuming you redeem your shares at the end of each period

Expense Example AllianzGI Income & Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	676	942	1,229	2,042
Class C	309	646	1,108	2,390
Class R	159	493	850	1,856

Example: Assuming you do not redeem your shares

Expense Example No Redemption AllianzGI Income & Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	676	942	1,229	2,042
Class C	209	646	1,108	2,390
Class R	159	493	850	1,856

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 129%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by investing primarily in a combination of common stocks and other equity securities, debt securities and convertible securities. The allocation of the Fund’s investments across asset classes will vary substantially from time to time. The Fund’s investments in each asset class are based upon the portfolio managers’ assessment of economic conditions and market factors, including equity price levels, interest rate levels and their anticipated direction. The portfolio managers will select common stocks by utilizing a fundamental, bottom-up research process intended to identify issuers whose financial fundamentals are expected to improve, and will select convertible or debt securities using a credit analysis that focuses on income producing characteristics. It is expected that a substantial portion of the Fund’s investments in debt securities and convertible securities will be rated below investment grade or unrated and determined to be of similar quality (“high-yield securities” or “junk bonds”). The Fund may invest in issuers of any market capitalization (with a focus on $3 billion and above) and may invest a portion of its assets in non-U.S. securities (including emerging market securities). Normally the Fund will employ a strategy of writing (selling) call options on the common stocks it holds; such strategy is intended to enhance Fund distributions and reduce overall portfolio risk, though there is no assurance that it will succeed. In addition to equity securities (such as preferred stocks and warrants), the Fund may invest in unregistered securities and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation (Derivatives Risk). Convertible and debt securities, particularly high-yield or junk bonds, are subject to greater levels of credit and liquidity risk, may be speculative and may decline in value due to changes in interest rates or an issuer’s deterioration or default (High Yield Risk, Convertible Securities Risk, Interest Rate Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Class A shares only. After-tax returns for other share classes will vary.

[1] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in equity securities of U.S. companies. The Fund currently defines “U.S. companies” as those companies that (i) are incorporated in the U.S., (ii) derive at least 50% of their revenue or profits from business activities in the U.S. or (iii) maintain at least 50% of their assets in the U.S. The Fund expects to invest typically in companies with market capitalizations at or above the lowest market capitalization of companies represented in the Russell 1000 Index (approximately $1.3 billion as of June 30, 2012). The Fund intends to utilize an investment strategy that focuses on the overall management of portfolio volatility. This focus may result in the Fund outperforming the general securities market during periods of flat or negative market performance, and underperforming the general securities market during periods of strong positive market performance.

The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security and sector selection decisions. Under the Sub-Adviser’s managed volatility strategy, the portfolio managers seek to emphasize stocks that exhibit a lower sensitivity to broader market movements (or “beta”), as they believe that stocks with higher betas are not rewarded with commensurately higher returns by the market. The portfolio construction process is iterative in nature. Initially, the portfolio managers build a fully invested and diversified portfolio subject to sector, capitalization and security constraints with a goal of minimizing total volatility as measured by the standard deviation of returns. The team then overlays a proprietary stock selection model and seeks to build a final portfolio of stocks that considers the trade off between volatility and sources of relative performance (or “alpha”). The portfolio managers consider whether to sell a particular security when any of the above factors materially changes, or when a more attractive investment candidate is available.

In addition to equity securities (such as preferred stocks, convertible securities and warrants) and equity-related instruments, the Fund may invest in securities issued in initial public offerings (IPOs), and utilize foreign currency exchange contracts, options, stock index futures contracts, warrants and other derivative instruments. Although the Fund does not expect to invest significantly in derivative instruments during its current fiscal year, it may do so at any time.

Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk).

[1] The Russell 1000 Index replaced the Russell 1000 Growth Index as the Fund's primary benchmark as of December 1, 2011 to reflect certain changes to the Fund's investment strategy.

[2] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

[3] "Management Fees" reflect the combination of investment advisory fees and administrative fees paid by the Fund to Allianz Global Investors Fund Management LLC ("AGIFM") under separate agreements. Fee rates are based on amounts incurred and fund asset levels during the last fiscal year and, where applicable, advisory fees have been restated to reflect current fee rates.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing in common stocks and other equity securities of companies representing a broad range of market capitalizations. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

AllianzGI Mid-Cap Fund

Investment Objective

The Fund seeks long-term capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees AllianzGI Mid-Cap Fund		Class A	Class B	Class C	Class R
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)		5.50%	none	none	none
Maximum Contingent Deferred Sales Charge (CDSC) (Load) (as a percentage of the lower of original purchase price or NAV	[1]	1.00%	5.00%	1.00%	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI Mid-Cap Fund	Class A	Class B	Class C	Class R
Management Fees	0.87%	0.87%	0.87%	0.87%
Distribution and/or Service (12b-1) Fees	0.25%	1.00%	1.00%	0.50%
Other Expenses	0.01%	0.01%	0.01%	0.01%
Total Annual Fund Operating Expenses	1.13%	1.88%	1.88%	1.38%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Example: Assuming you redeem your shares at the end of each period

Expense Example AllianzGI Mid-Cap Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	659	889	1,138	1,849
Class B	691	891	1,216	1,914
Class C	291	591	1,016	2,201
Class R	140	437	755	1,657

Example: Assuming you do not redeem your shares

Expense Example No Redemption AllianzGI Mid-Cap Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	659	889	1,138	1,849
Class B	191	591	1,016	1,914
Class C	191	591	1,016	2,201
Class R	140	437	755	1,657

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 303%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of medium-sized companies. The Fund currently defines medium-sized companies as those having market capitalizations comparable to those companies included in the Russell Midcap Growth Index (between $1.3 billion and $19.1 billion as of June 30, 2012). The Fund normally invests primarily in equity securities of U.S. companies. The portfolio managers ordinarily look for companies with the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs) and in non-U.S. securities, and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments.  Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Class A shares only. After-tax returns for other share classes will vary.

[1] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
AllianzGI Wellness Fund Class D	149	462	797	1,746

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 95%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in wellness-related companies. The Fund may invest in U.S. and non-U.S. companies, and currently expects the majority of its non-U.S. investments will normally be in Asia and Western Europe. The Fund may invest up to 15% of its assets in companies organized or headquartered in emerging market countries (but no more than 10% in any one emerging market country). The Fund will invest primarily in common stocks and other equity securities. Although the Fund may invest in companies of any market capitalization, the Fund does not intend to invest more than 15% of its assets in companies with market capitalizations below $100 million. The portfolio managers consider wellness-related companies to include companies in the healthcare industry and other companies that provide products or services that promote or aid in achieving a healthy lifestyle. The portfolio managers develop forecasts of economic growth, inflation and interest rates that are used to help identify regions and countries that are likely to offer the best investment opportunities. The portfolio managers may consider the anticipated economic growth rate, political outlook, inflation rate, currency outlook and interest rate environment for the country and the region in which a company is located. The portfolio managers ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through either an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. The Fund is “non-diversified,” which means that it may invest a significant portion of its assets in a relatively small number of issuers, which may increase risk. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs), and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund may invest in derivatives of any kind, it expects to write (sell) put and call options on securities for hedging, risk management or other purposes.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity
Securities Risk, Smaller Company Risk). Focusing on a limited number of issuers, sectors (such as the wellness sector), industries, or geographic regions increases risk and volatility (Focused Investment Risk (Wellness-Related Risk)). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index, a sector-specific custom benchmark and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class D shares. For periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results for the Fund that are higher or lower than the actual results of the predecessor fund, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 199%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in equity securities of U.S. companies. The Fund currently defines “U.S. companies” as those companies that (i) are incorporated in the U.S., (ii) derive at least 50% of their revenue or profits from business activities in the U.S. or (iii) maintain at least 50% of their assets in the U.S. The Fund expects to invest typically in companies with market capitalizations at or above the lowest market capitalization of companies represented in the Russell 1000 Index (approximately $1.3 billion as of June 30, 2012). The Fund intends to utilize an investment strategy that focuses on the overall management of portfolio volatility. This focus may result in the Fund outperforming the general securities market during periods of flat or negative market performance, and underperforming the general securities market during periods of strong positive market performance.

The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security and sector selection decisions. Under the Sub-Adviser’s managed volatility strategy, the portfolio managers seek to emphasize stocks that exhibit a lower sensitivity to broader market movements (or “beta”), as they believe that stocks with higher betas are not rewarded with commensurately higher returns by the market. The portfolio construction process is iterative in nature. Initially, the portfolio managers build a fully invested and diversified portfolio subject to sector, capitalization and security constraints with a goal of minimizing total volatility as measured by the standard deviation of returns. The team then overlays a proprietary stock selection model and seeks to build a final portfolio of stocks that considers the trade off between volatility and sources of relative performance (or “alpha”). The portfolio managers consider whether to sell a particular security when any of the above factors materially changes, or when a more attractive investment candidate is available.

In addition to equity securities (such as preferred stocks, convertible securities and warrants) and equity-related instruments, the Fund may invest in securities issued in initial public offerings (IPOs), and utilize foreign currency exchange contracts, options, stock index futures contracts, warrants and other derivative instruments. Although the Fund does not expect to invest significantly in derivative instruments during its current fiscal year, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B and Class C performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information. Prior to December 1, 2011, the Fund was managed pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy.

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 26%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with smaller market capitalizations. The Fund currently considers smaller market capitalization companies to be companies with market capitalizations of between $100 million and $3.5 billion. The Fund normally invests significantly in securities of companies that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and non-U.S. securities, including emerging market securities.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 27%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with medium market capitalizations. The Fund currently defines medium market capitalization companies as those companies with market capitalizations between $2 billion and $17.5 billion. Effective December 1, 2011, consistent with the type of investments suggested by the Fund’s name, the Fund adopted the 80% test referred to above. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest up to 25% of its assets in non-U.S. securities, including emerging market securities (without limit in American Depositary Receipts (ADRs)) and may invest up to 20% of its assets in real estate investment trusts (REITs).

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information. Prior to December 1, 2011, the Fund was managed pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy.

AllianzGI Focused Growth Fund

Investment Objective

The Fund seeks capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees AllianzGI Focused Growth Fund		Class A	Class B	Class C	Class R
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)		5.50%	none	none	none
Maximum Contingent Deferred Sales Charge (CDSC) (Load) (as a percentage of the lower of original purchase price or NAV	[1]	1.00%	5.00%	1.00%	none

Total Annual Fund Operating Expenses		1.11%	1.86%	1.86%	1.36%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Example: Assuming you redeem your shares at the end of each period

Expense Example AllianzGI Focused Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	657	883	1,128	1,827
Class B	689	885	1,206	1,892
Class C	289	585	1,006	2,180
Class R	138	431	745	1,635

Example: Assuming you do not redeem your shares

Expense Example No Redemption AllianzGI Focused Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	657	883	1,128	1,827
Class B	189	585	1,006	1,892
Class C	189	585	1,006	2,180
Class R	138	431	745	1,635

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 81%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing primarily in equity securities of U.S. companies with market capitalizations of at least $1 billion. The Fund may also invest up to 20% of its assets in non-U.S. securities (but no more than 10% in any one non-U.S. country or 10% in companies organized or headquartered in emerging market countries). At times, depending on market and other conditions, the Fund may also invest a significant percentage of its assets in a small number of business sectors or industries. The portfolio managers are constrained to only including the 25-45 highest conviction large cap growth stocks covered by the research team.

The portfolio managers believe the securities in the Fund exhibit the greatest combination of earnings growth potential, quality (as reflected in consistent business fundamentals) and attractive valuation. The portfolio managers ordinarily look for several of the following characteristics when analyzing specific companies for possible investment: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue, cash flow or earnings through either an expanding market or expanding market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Focusing on a limited number of issuers, sectors, industries, or geographic regions increases risk and volatility (Focused Investment Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Prior to September 24, 2012, the Fund was managed by a different sub-adviser pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Class A shares only. After-tax returns for other share classes will vary.

[1] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

[1] "Management Fees" reflect the combination of investment advisory fees and administrative fees paid by the Fund to Allianz Global Investors Fund Management LLC ("AGIFM") under separate agreements. Fee rates are based on amounts incurred and fund asset levels during the last fiscal year and, where applicable, advisory fees have been restated to reflect current fee rates.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 190%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in equity securities of companies principally engaged in the research, development, manufacturing, extraction, distribution or sale of materials, energy or goods related to the Agriculture, Energy, Materials or Commodity-Related Industrials sectors. The Fund considers (i) the Agriculture sector to include products such as grain, vegetable oils, livestock and agricultural-type products such as coffee; (ii) the Energy sector to include products such as coal, natural gas, oil, alternative energy and electricity; (iii) the Materials sector to include products such as chemicals & fertilizers, constructions materials, industrial metal, precious metal, steel, minerals and paper products; and (iv) the Commodity-Related Industrials sector to include industrial firms that manufacture tools, equipment and goods used in the development and production of commodities or that maintain infrastructure used in their transportation. The Fund also has a fundamental policy to invest at least 25% of its total assets in the “natural resources” sector, as described in the SAI. Under normal conditions, the portfolio managers seek to allocate investments such that the Fund has exposure to a diverse range of commodities within each of the three primary commodity sectors of Agriculture, Energy and Materials. The Fund expects to invest most of its assets in U.S. and non-U.S. common stocks. Under normal circumstances, the Fund will invest a minimum of 1/3 of its assets in non-U.S. securities and will invest in companies organized or headquartered in at least eight countries including the United States. The Fund may also invest up to 10% of its net assets in securities issued by other investment companies, included exchange-traded funds (“ETFs”).

The Fund’s portfolio managers evaluate the relative attractiveness of individual commodity cycles, including supply-demand fundamentals, pricing outlook and impact on U.S. and non-U.S. macroeconomic indicators like inflation. In addition, the portfolio managers may consider forecasts of economic growth, inflation and interest rates to help identify industry sectors, regions and individual countries (including emerging market countries) that they believe are likely to offer the best investment opportunities. The portfolio managers seek to evaluate the correlation of degree to which companies’ earnings are linked to commodity price changes, as well as companies’ fundamental value and prospects for growth.

In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Focusing on a limited number of issuers, sectors (such as the commodity sectors), industries, or geographic regions increases risk and volatility (Focused Investment Risk (Commodity-Related Companies Risk)). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index, sector-specific custom benchmarks and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class C performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with large market capitalizations. The Fund currently considers a company’s market capitalization to be large if it equals or exceeds the market capitalization of the 400th largest company represented in the Russell 1000 Index (i.e., a market capitalization of at least approximately $7 billion as of June 30, 2012). The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 95%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in wellness-related companies. The Fund may invest in U.S. and non-U.S. companies, and currently expects the majority of its non-U.S. investments will normally be in Asia and Western Europe. The Fund may invest up to 15% of its assets in companies organized or headquartered in emerging market countries (but no more than 10% in any one emerging market country). The Fund will invest primarily in common stocks and other equity securities. Although the Fund may invest in companies of any market capitalization, the Fund does not intend to invest more than 15% of its assets in companies with market capitalizations below $100 million. The portfolio managers consider wellness-related companies to include companies in the healthcare industry and other companies that provide products or services that promote or aid in achieving a healthy lifestyle. The portfolio managers develop forecasts of economic growth, inflation and interest rates that are used to help identify regions and countries that are likely to offer the best investment opportunities. The portfolio managers may consider the anticipated economic growth rate, political outlook, inflation rate, currency outlook and interest rate environment for the country and the region in which a company is located. The portfolio managers ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through either an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. The Fund is “non-diversified,” which means that it may invest a significant portion of its assets in a relatively small number of issuers, which may increase risk. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs), and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund may invest in derivatives of any kind, it expects to write (sell) put and call options on securities for hedging, risk management or other purposes.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity
Securities Risk, Smaller Company Risk). Focusing on a limited number of issuers, sectors (such as the wellness sector), industries, or geographic regions increases risk and volatility (Focused Investment Risk (Wellness-Related Risk)). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index, a sector-specific custom benchmark and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class D shares. For periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results for the Fund that are higher or lower than the actual results of the predecessor fund, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 80%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in companies with market capitalizations comparable to those of companies included in the MSCI World Small-Cap Index (between $11.4 million and $5.6 billion as of June 30, 2012). Under normal market and other conditions, the Fund expects to maintain a weighted-average market capitalization between 50% and 200% of the weighted-average market capitalization of the securities in the MSCI World Small-Cap Index, which as of June 30, 2012 would permit the Fund to maintain a weighted-average market capitalization ranging from $929 million to $3.7 billion. The Fund normally invests in companies organized or headquartered in at least eight different countries (one of which may be the United States) and expects that the majority of its non-U.S. investments will normally be in Japan and Western Europe. The Fund will normally invest no more than 25% of its assets in issuers that are organized or headquartered in any one country outside the U.S., other than France, Germany, Japan and the United Kingdom. The Fund may invest up to 30% of its assets in companies organized or headquartered in emerging market countries (but no more than 10% in any one emerging market country). Regional portfolio managers in the United States, Europe and Asia collaborate to produce a portfolio that is believed likely to have the best investment opportunities from each of those regions. The allocation of Fund assets among these three regions is set from time to time and periodically adjusted through a collaborative effort among the most senior portfolio manager in the regions.

The portfolio managers in Europe and Asia develop forecasts of economic growth, inflation and interest rates that are used to help identify countries and other geographies within the applicable region that are likely to offer the best investment opportunities. The portfolio managers may consider the anticipated economic growth rate, political outlook, inflation rate, currency outlook and interest rate environment for the country and the region in which a company is located. The portfolio managers in Europe and Asia ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through either an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services.

The portfolio managers in the United States follow a disciplined, fundamental bottom-up research process focusing on North American companies with sustainable growth characteristics that are undergoing positive fundamental change. The portfolio managers look for what they believe to be the best risk-reward candidates within the investment universe, defined as equities that are expected to appreciate based on accelerating fundamental performance, rising expectations and related multiple expansion. Company-specific research includes industry and competitive analysis, revenue model analysis, profit analysis and balance sheet assessment. Once the portfolio managers in the United States believe that positive fundamental change is occurring and will likely lead to accelerating fundamental performance, they seek evidence that performance will be a longer-term sustainable trend. Lastly, these portfolio managers determine if the investment is timely with regard to relative valuation and price strength, exploiting stocks that are under-priced relative to their potential.

In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs), and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B and Class C performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Class A shares only. After-tax returns for other share classes will vary.

[1] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

[1] "Management Fees" reflect the combination of investment advisory fees and administrative fees paid by the Fund to Allianz Global Investors Fund Management LLC ("AGIFM") under separate agreements. Fee rates are based on amounts incurred and fund asset levels during the last fiscal year and, where applicable, advisory fees have been restated to reflect current fee rates.

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Example: Assuming you redeem your shares at the end of each period

Class R	138	431	745	1,635

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 27%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with large market capitalizations. The Fund currently considers a company’s market capitalization to be large if it equals or exceeds the market capitalization of the 400th largest company represented in the Russell 1000 Index (i.e., a market capitalization of at least approximately $7 billion as of June 30, 2012). The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 130%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 65% of its assets in common stocks of “growth” companies with market capitalizations of less than $2 billion. The portfolio managers’ investment process focuses on bottom-up, fundamental analysis. The portfolio managers consider “growth” companies to include companies that they believe to have above-average growth prospects (relative to companies in the same industry or the market as a whole). In seeking to identify these companies, the portfolio managers will consider fundamental characteristics such as revenue growth, volume and pricing trends, profit margin behavior, margin expansion opportunities, financial strength, cash flow growth, asset value growth and earnings growth. The investment process includes both quantitative and qualitative analysis. Once a potential investment is identified, the portfolio managers conduct a quantitative analysis to determine if the security is reasonably priced with respect to its peer group on a historical and current basis. Then fundamental research is conducted, focusing on a review of financial statements and third-party research. The portfolio managers seek to diversify the portfolio among different industries. The Fund may invest in securities issued in initial public offerings (IPOs) and up to 15% of its assets in non-U.S. securities (without limit in American Depositary Receipts (ADRs)).

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by investing primarily in a combination of common stocks and other equity securities, debt securities and convertible securities. The allocation of the Fund’s investments across asset classes will vary substantially from time to time. The Fund’s investments in each asset class are based upon the portfolio managers’ assessment of economic conditions and market factors, including equity price levels, interest rate levels and their anticipated direction. The portfolio managers will select common stocks by utilizing a fundamental, bottom-up research process intended to identify issuers whose financial fundamentals are expected to improve, and will select convertible or debt securities using a credit analysis that focuses on income producing characteristics. It is expected that a substantial portion of the Fund’s investments in debt securities and convertible securities will be rated below investment grade or unrated and determined to be of similar quality (“high-yield securities” or “junk bonds”). The Fund may invest in issuers of any market capitalization (with a focus on $3 billion and above) and may invest a portion of its assets in non-U.S. securities (including emerging market securities). Normally the Fund will employ a strategy of writing (selling) call options on the common stocks it holds; such strategy is intended to enhance Fund distributions and reduce overall portfolio risk, though there is no assurance that it will succeed. In addition to equity securities (such as preferred stocks and warrants), the Fund may invest in unregistered securities and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation (Derivatives Risk). Convertible and debt securities, particularly high-yield or junk bonds, are subject to greater levels of credit and liquidity risk, may be speculative and may decline in value due to changes in interest rates or an issuer’s deterioration or default (High Yield Risk, Convertible Securities Risk, Interest Rate Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

Investment Objective

The Fund seeks long-term growth of capital and income.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Example: Assuming you redeem your shares at the end of each period

Expense Example AllianzGI NFJ Dividend Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	652	869	1,103	1,773
Class B	684	869	1,180	1,837
Class C	284	569	980	2,127
Class R	133	415	718	1,579

Example: Assuming you do not redeem your shares

Expense Example No Redemption AllianzGI NFJ Dividend Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	652	869	1,103	1,773
Class B	184	569	980	1,837
Class C	184	569	980	2,127
Class R	133	415	718	1,579

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 42%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies that pay or are expected to pay dividends. Under normal conditions, the Fund will invest primarily in common stocks of companies with market capitalizations greater than $3.5 billion. The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. In addition, a portion of the securities selected for the Fund are identified primarily on the basis of their dividend yields. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

Strategy [Heading]

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in companies with market capitalizations comparable to those of companies included in the MSCI World Small-Cap Index (between $11.4 million and $5.6 billion as of June 30, 2012). Under normal market and other conditions, the Fund expects to maintain a weighted-average market capitalization between 50% and 200% of the weighted-average market capitalization of the securities in the MSCI World Small-Cap Index, which as of June 30, 2012 would permit the Fund to maintain a weighted-average market capitalization ranging from $929 million to $3.7 billion. The Fund normally invests in companies organized or headquartered in at least eight different countries (one of which may be the United States) and expects that the majority of its non-U.S. investments will normally be in Japan and Western Europe. The Fund will normally invest no more than 25% of its assets in issuers that are organized or headquartered in any one country outside the U.S., other than France, Germany, Japan and the United Kingdom. The Fund may invest up to 30% of its assets in companies organized or headquartered in emerging market countries (but no more than 10% in any one emerging market country). Regional portfolio managers in the United States, Europe and Asia collaborate to produce a portfolio that is believed likely to have the best investment opportunities from each of those regions. The allocation of Fund assets among these three regions is set from time to time and periodically adjusted through a collaborative effort among the most senior portfolio manager in the regions.

The portfolio managers in Europe and Asia develop forecasts of economic growth, inflation and interest rates that are used to help identify countries and other geographies within the applicable region that are likely to offer the best investment opportunities. The portfolio managers may consider the anticipated economic growth rate, political outlook, inflation rate, currency outlook and interest rate environment for the country and the region in which a company is located. The portfolio managers in Europe and Asia ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through either an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services.

The portfolio managers in the United States follow a disciplined, fundamental bottom-up research process focusing on North American companies with sustainable growth characteristics that are undergoing positive fundamental change. The portfolio managers look for what they believe to be the best risk-reward candidates within the investment universe, defined as equities that are expected to appreciate based on accelerating fundamental performance, rising expectations and related multiple expansion. Company-specific research includes industry and competitive analysis, revenue model analysis, profit analysis and balance sheet assessment. Once the portfolio managers in the United States believe that positive fundamental change is occurring and will likely lead to accelerating fundamental performance, they seek evidence that performance will be a longer-term sustainable trend. Lastly, these portfolio managers determine if the investment is timely with regard to relative valuation and price strength, exploiting stocks that are under-priced relative to their potential.

In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs), and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 80%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in companies with market capitalizations comparable to those of companies included in the MSCI World Small-Cap Index (between $11.4 million and $5.6 billion as of June 30, 2012). Under normal market and other conditions, the Fund expects to maintain a weighted-average market capitalization between 50% and 200% of the weighted-average market capitalization of the securities in the MSCI World Small-Cap Index, which as of June 30, 2012 would permit the Fund to maintain a weighted-average market capitalization ranging from $929 million to $3.7 billion. The Fund normally invests in companies organized or headquartered in at least eight different countries (one of which may be the United States) and expects that the majority of its non-U.S. investments will normally be in Japan and Western Europe. The Fund will normally invest no more than 25% of its assets in issuers that are organized or headquartered in any one country outside the U.S., other than France, Germany, Japan and the United Kingdom. The Fund may invest up to 30% of its assets in companies organized or headquartered in emerging market countries (but no more than 10% in any one emerging market country). Regional portfolio managers in the United States, Europe and Asia collaborate to produce a portfolio that is believed likely to have the best investment opportunities from each of those regions. The allocation of Fund assets among these three regions is set from time to time and periodically adjusted through a collaborative effort among the most senior portfolio manager in the regions.

The portfolio managers in Europe and Asia develop forecasts of economic growth, inflation and interest rates that are used to help identify countries and other geographies within the applicable region that are likely to offer the best investment opportunities. The portfolio managers may consider the anticipated economic growth rate, political outlook, inflation rate, currency outlook and interest rate environment for the country and the region in which a company is located. The portfolio managers in Europe and Asia ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through either an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services.

The portfolio managers in the United States follow a disciplined, fundamental bottom-up research process focusing on North American companies with sustainable growth characteristics that are undergoing positive fundamental change. The portfolio managers look for what they believe to be the best risk-reward candidates within the investment universe, defined as equities that are expected to appreciate based on accelerating fundamental performance, rising expectations and related multiple expansion. Company-specific research includes industry and competitive analysis, revenue model analysis, profit analysis and balance sheet assessment. Once the portfolio managers in the United States believe that positive fundamental change is occurring and will likely lead to accelerating fundamental performance, they seek evidence that performance will be a longer-term sustainable trend. Lastly, these portfolio managers determine if the investment is timely with regard to relative valuation and price strength, exploiting stocks that are under-priced relative to their potential.

In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs), and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).

[1] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

[2] "Management Fees" reflect the combination of investment advisory fees and administrative fees paid by the Fund to Allianz Global Investors Fund Management LLC ("AGIFM") under separate agreements. Fee rates are based on amounts incurred and fund asset levels during the last fiscal year and, where applicable, advisory fees have been restated to reflect current fee rates.

Portfolio Turnover [Text Block]

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 303%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Expense Example Narrative [Text Block]

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of medium-sized companies. The Fund currently defines medium-sized companies as those having market capitalizations comparable to those companies included in the Russell Midcap Growth Index (between $1.3 billion and $19.1 billion as of June 30, 2012). The Fund normally invests primarily in equity securities of U.S. companies. The portfolio managers ordinarily look for companies with the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs) and in non-U.S. securities, and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments.  Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

AllianzGI NFJ All-Cap Value Fund

Investment Objective

The Fund seeks long-term growth of capital and income.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment): None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI NFJ All-Cap Value Fund	Institutional	Class P	Administrative	Class D
Management Fees	0.95%	1.05%	0.95%	1.05%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Expense Example AllianzGI NFJ All-Cap Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional	98	306	531	1,178

Administrative	123	384	665	1,466
Class D	133	415	718	1,579

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 36%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing in common stocks and other equity securities of companies representing a broad range of market capitalizations. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Institutional Class shares only. After-tax returns for other share classes will vary.

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 95%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in wellness-related companies. The Fund may invest in U.S. and non-U.S. companies, and currently expects the majority of its non-U.S. investments will normally be in Asia and Western Europe. The Fund may invest up to 15% of its assets in companies organized or headquartered in emerging market countries (but no more than 10% in any one emerging market country). The Fund will invest primarily in common stocks and other equity securities. Although the Fund may invest in companies of any market capitalization, the Fund does not intend to invest more than 15% of its assets in companies with market capitalizations below $100 million. The portfolio managers consider wellness-related companies to include companies in the healthcare industry and other companies that provide products or services that promote or aid in achieving a healthy lifestyle. The portfolio managers develop forecasts of economic growth, inflation and interest rates that are used to help identify regions and countries that are likely to offer the best investment opportunities. The portfolio managers may consider the anticipated economic growth rate, political outlook, inflation rate, currency outlook and interest rate environment for the country and the region in which a company is located. The portfolio managers ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through either an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. The Fund is “non-diversified,” which means that it may invest a significant portion of its assets in a relatively small number of issuers, which may increase risk. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs), and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund may invest in derivatives of any kind, it expects to write (sell) put and call options on securities for hedging, risk management or other purposes.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Focusing on a limited number of issuers, sectors (such as the wellness sector), industries, or geographic regions increases risk and volatility (Focused Investment Risk (Wellness-Related Risk)). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index, a sector-specific custom benchmark and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B and Class C performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI.

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of technology companies and in derivatives and other synthetic instruments that have economic characteristics similar to equity securities of technology companies. Derivatives transactions may have the effect of either magnifying or limiting the Fund’s gains and losses. The Fund normally invests in companies organized or headquartered in at least three different countries and may invest up to 50% of its assets in non-U.S. issuers, including those organized or headquartered in emerging market countries, but normally no more than 25% of its assets are invested in issuers organized or headquartered in any one country outside the United States, other than Japan. The Fund intends to invest primarily in companies with market capitalizations greater than $500 million, with no more than 15% of its assets in technology companies with market capitalizations below $100 million. The Fund is “non-diversified,” which means that it may invest a significant portion of its assets in a relatively small number of issuers, which may increase risk. The portfolio managers define technology companies as those that provide technology products or services or utilize technology to gain competitive advantages. The portfolio managers evaluate fundamental value and growth prospects and focus on companies that they expect will have higher than average rates of growth and strong potential for capital appreciation. The portfolio managers develop forecasts of economic growth, inflation and interest rates that are used to help identify regions and countries that are likely to offer the best investment opportunities. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs) and may utilize foreign currency exchange contracts, options, futures and forward contracts, short sales, swap agreements and other derivative instruments. Although the Fund may invest in derivatives of any kind, it expects to invest in options, swaps and, to a lesser extent, foreign exchange contracts. The Fund may write call options on individual securities that it does not hold in its portfolio (i.e., “naked” call options) as well as call options on indices and exchange-traded funds. The Fund ordinarily expects to use derivative instruments in an attempt to enhance the Fund’s investment returns, to hedge against market and other risks or to obtain market exposure. The Fund may enter into credit default, cross-currency, interest rate, total return, variance and other forms of swap agreements in order to manage its exposure to credit, currency and interest rate risk.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 170%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing in a portfolio of international equities that manages overall portfolio volatility. The Fund normally invests primarily in equity securities of companies located outside of the U.S., and will not invest more than 50% of its net assets in companies within any single country. The Fund ordinarily allocates its investments among a number of different countries, including those in the MSCI EAFE Index and normally invests at least 80% of its assets in non-U.S. securities. The Fund normally focuses its non-U.S. investments in developed countries but may also invest in emerging markets securities. The Fund may invest in issuers of any market capitalization, including smaller capitalization companies. The Fund intends to utilize an investment strategy that focuses on the overall management of portfolio volatility. This focus may result in the Fund outperforming the general securities market during periods of flat or negative market performance, and underperforming the general securities market during periods of strong positive market performance.

The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security and sector selection decisions. Under the Sub-Adviser’s managed volatility strategy, the portfolio managers seek to emphasize stocks that exhibit a lower sensitivity to broader market movements (or “beta”), as they believe that stocks with higher betas are not rewarded with commensurately higher returns by the market. The portfolio construction process is iterative in nature. Initially, the portfolio managers build a fully invested and diversified portfolio subject to sector and security constraints with a goal of minimizing total volatility as measured by the standard deviation of returns. The team then overlays a proprietary stock selection model and seeks to build a final portfolio of stocks that considers the trade off between volatility and sources of relative performance (or “alpha”). The portfolio managers consider whether to sell a particular security when any of the above factors materially changes, or when a more attractive investment candidate is available.

In addition to equity securities (such as preferred stocks, convertible securities and warrants) and equity-related instruments, the Fund may invest in securities issued in initial public offerings (IPOs), and utilize foreign currency exchange contracts, options, stock index futures contracts, warrants and other derivative instruments. Although the Fund does not expect to invest significantly in derivative instruments during its current fiscal year, it may do so at any time.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information. Prior to February 1, 2012, the Fund was managed pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy.

[1] "Management Fees" reflect the combination of investment advisory fees and administrative fees paid by the Fund to Allianz Global Investors Fund Management LLC ("AGIFM") under separate agreements. Fee rates are based on amounts incurred and fund asset levels during the last fiscal year and, where applicable, advisory fees have been restated to reflect current fee rates.

[2] Effective November 1, 2012, AGIFM has contractually agreed to observe, through October 31, 2013, an irrevocable waiver of a portion of its administrative fees (together with advisory fees paid to AGIFM, a component of "Management Fees"), which reduces the contractual fee rate by 0.20%.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 38%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 65% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities (such as preferred stocks, convertible securities and warrants) of non-U.S. companies with market capitalizations greater than $1 billion. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The Fund may invest up to 50% of its assets in emerging market securities. The Fund may also achieve its exposure to non-U.S. equity securities through investing in American Depositary Receipts (ADRs). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

AllianzGI Large-Cap Growth Fund

Investment Objective

The Fund seeks long-term capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees AllianzGI Large-Cap Growth Fund		Class A	Class B	Class C	Class R

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Example: Assuming you redeem your shares at the end of each period

Expense Example AllianzGI Large-Cap Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	652	879	1,123	1,823
Class B	684	880	1,201	1,888
Class C	284	580	1,001	2,176
Class R	133	426	740	1,631

Example: Assuming you do not redeem your shares

Expense Example No Redemption AllianzGI Large-Cap Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	652	879	1,123	1,823
Class B	184	580	1,001	1,888
Class C	184	580	1,001	2,176
Class R	133	426	740	1,631

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 46%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of U.S. companies with market capitalizations of at least $5 billion. The Fund may also invest up to 20% of its assets in non-U.S. securities (but no more than 10% in any one non-U.S. country or 10% in companies organized or headquartered in emerging market countries). At times, the Fund may also invest significantly in a small number of business sectors or industries. In analyzing specific companies, the portfolio managers ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue, cash flow or earnings through an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Class A shares only. After-tax returns for other share classes will vary.

[1] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

[1] Effective November 1, 2012, AGIFM has contractually agreed to observe, through October 31, 2013, an irrevocable waiver of a portion of its advisory fees (together with administrative fees paid to AGIFM, a component of "Management Fees"), which reduces the 0.45% contractual fee rate by 0.05% to 0.40%.

The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies that pay or are expected to pay dividends. Under normal conditions, the Fund will invest primarily in common stocks of companies with market capitalizations greater than $3.5 billion. The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. In addition, a portion of the securities selected for the Fund are identified primarily on the basis of their dividend yields. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk(non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

AllianzGI NFJ International Value Fund

Investment Objective

The Fund seeks long-term growth of capital and income.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment): None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI NFJ International Value Fund		Institutional	Class P	Administrative	Class D
Management Fees		0.94%	1.04%	0.94%	1.04%

Total Annual Fund Operating Expenses After Expense Reductions	[1]	0.90%	1.00%	1.15%	1.25%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Expense Example AllianzGI NFJ International Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional	92	298	521	1,162
Class P	102	329	575	1,278
Administrative	117	376	655	1,450
Class D	127	407	708	1,563

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 38%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 65% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities (such as preferred stocks, convertible securities and warrants) of non-U.S. companies with market capitalizations greater than $1 billion. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The Fund may invest up to 50% of its assets in emerging market securities. The Fund may also achieve its exposure to non-U.S. equity securities through investing in American Depositary Receipts (ADRs). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of U.S. companies with market capitalizations of at least $5 billion. The Fund may also invest up to 20% of its assets in non-U.S. securities (but no more than 10% in any one non-U.S. country or 10% in companies organized or headquartered in emerging market countries). At times, the Fund may also invest significantly in a small number of business sectors or industries. In analyzing specific companies, the portfolio managers ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue, cash flow or earnings through an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 27%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with large market capitalizations. The Fund currently considers a company’s market capitalization to be large if it equals or exceeds the market capitalization of the 400th largest company represented in the Russell 1000 Index (i.e., a market capitalization of at least approximately $7 billion as of June 30, 2012). The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).

The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads).

AllianzGI NFJ Dividend Value Fund

Investment Objective

The Fund seeks long-term growth of capital and income.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment): None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI NFJ Dividend Value Fund	Institutional	Class P	Administrative	Class D
Management Fees	0.70%	0.80%	0.70%	0.80%
Distribution and/or Service (12b-1) Fees	none	none	0.25%	0.25%
Other Expenses	0.01%	0.01%	0.01%	0.01%
Total Fund Operating Expenses	0.71%	0.81%	0.96%	1.06%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Expense Example AllianzGI NFJ Dividend Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional	73	227	395	883
Class P	83	259	450	1,002
Administrative	98	306	531	1,178
Class D	108	337	585	1,294

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 42%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies that pay or are expected to pay dividends. Under normal conditions, the Fund will invest primarily in common stocks of companies with market capitalizations greater than $3.5 billion. The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. In addition, a portion of the securities selected for the Fund are identified primarily on the basis of their dividend yields. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk(non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Institutional Class shares only. After-tax returns for other share classes will vary.

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 303%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of medium-sized companies. The Fund currently defines medium-sized companies as those having market capitalizations comparable to those companies included in the Russell Midcap Growth Index (between $1.3 billion and $19.1 billion as of June 30, 2012). The Fund normally invests primarily in equity securities of U.S. companies. The portfolio managers ordinarily look for companies with the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs) and in non-U.S. securities, and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by investing primarily in a combination of common stocks and other equity securities, debt securities and convertible securities. The allocation of the Fund’s investments across asset classes will vary substantially from time to time. The Fund’s investments in each asset class are based upon the portfolio managers’ assessment of economic conditions and market factors, including equity price levels, interest rate levels and their anticipated direction. The portfolio managers will select common stocks by utilizing a fundamental, bottom-up research process intended to identify issuers whose financial fundamentals are expected to improve, and will select convertible or debt securities using a credit analysis that focuses on income producing characteristics. It is expected that a substantial portion of the Fund’s investments in debt securities and convertible securities will be rated below investment grade or unrated and determined to be of similar quality (“high-yield securities” or “junk bonds”). The Fund may invest in issuers of any market capitalization (with a focus on $3 billion and above) and may invest a portion of its assets in non-U.S. securities (including emerging market securities). Normally the Fund will employ a strategy of writing (selling) call options on the common stocks it holds; such strategy is intended to enhance Fund distributions and reduce overall portfolio risk, though there is no assurance that it will succeed. In addition to equity securities (such as preferred stocks and warrants), the Fund may invest in unregistered securities and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation (Derivatives Risk). Convertible and debt securities, particularly high-yield or junk bonds, are subject to greater levels of credit and liquidity risk, may be speculative and may decline in value due to changes in interest rates or an issuer’s deterioration or default (High Yield Risk, Convertible Securities Risk, Interest Rate Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

AllianzGI Focused Growth Fund | AllianzGI Focused Growth Fund

AllianzGI Focused Growth Fund

Investment Objective

The Fund seeks capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment): None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI Focused Growth Fund		Institutional	Class P	Administrative	Class D
Management Fees	[1]	0.75%	0.85%	0.75%	0.85%
Distribution and/or Service (12b-1) Fees		none	none	0.25%	0.25%
Other Expenses		0.01%	0.01%	0.01%	0.01%
Total Fund Operating Expenses		0.76%	0.86%	1.01%	1.11%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Expense Example AllianzGI Focused Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional	78	243	422	942
Class P	88	274	477	1,061
Administrative	103	322	558	1,236
Class D	113	353	612	1,352

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 81%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing primarily in equity securities of U.S. companies with market capitalizations of at least $1 billion. The Fund may also invest up to 20% of its assets in non-U.S. securities (but no more than 10% in any one non-U.S. country or 10% in companies organized or headquartered in emerging market countries). At times, depending on market and other conditions, the Fund may also invest a significant percentage of its assets in a small number of business sectors or industries. The portfolio managers are constrained to only including the 25-45 highest conviction large cap growth stocks covered by the research team.

The portfolio managers believe the securities in the Fund exhibit the greatest combination of earnings growth potential, quality (as reflected in consistent business fundamentals) and attractive valuation. The portfolio managers ordinarily look for several of the following characteristics when analyzing specific companies for possible investment: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue, cash flow or earnings through either an expanding market or expanding market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Focusing on a limited number of issuers, sectors, industries, or geographic regions increases risk and volatility (Focused Investment Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class.

Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Prior to September 24, 2012, the Fund was managed by a different sub-adviser pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

Class C	203	638	1,099	2,375
Class R	153	485	840	1,841

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 38%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 65% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities (such as preferred stocks, convertible securities and warrants) of non-U.S. companies with market capitalizations greater than $1 billion. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The Fund may invest up to 50% of its assets in emerging market securities. The Fund may also achieve its exposure to non-U.S. equity securities through investing in American Depositary Receipts (ADRs). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Class A shares only. After-tax returns for other share classes will vary.

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Expense Example AllianzGI International Managed Volatility Fund (USD $)	1 Year	3 Years	5 Years	10 Years

Class D	98	349	619	1,391

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 170%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing in a portfolio of international equities that manages overall portfolio volatility. The Fund normally invests primarily in equity securities of companies located outside of the U.S., and will not invest more than 50% of its net assets in companies within any single country. The Fund ordinarily allocates its investments among a number of different countries, including those in the MSCI EAFE Index and normally invests at least 80% of its assets in non-U.S. securities. The Fund normally focuses its non-U.S. investments in developed countries but may also invest in emerging markets securities. The Fund may invest in issuers of any market capitalization, including smaller capitalization companies. The Fund intends to utilize an investment strategy that focuses on the overall management of portfolio volatility. This focus may result in the Fund outperforming the general securities market during periods of flat or negative market performance, and underperforming the general securities market during periods of strong positive market performance.

The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security and sector selection decisions. Under the Sub-Adviser’s managed volatility strategy, the portfolio managers seek to emphasize stocks that exhibit a lower sensitivity to broader market movements (or “beta”), as they believe that stocks with higher betas are not rewarded with commensurately higher returns by the market. The portfolio construction process is iterative in nature. Initially, the portfolio managers build a fully invested and diversified portfolio subject to sector and security constraints with a goal of minimizing total volatility as measured by the standard deviation of returns. The team then overlays a proprietary stock selection model and seeks to build a final portfolio of stocks that considers the trade off between volatility and sources of relative performance (or “alpha”). The portfolio managers consider whether to sell a particular security when any of the above factors materially changes, or when a more attractive investment candidate is available.

In addition to equity securities (such as preferred stocks, convertible securities and warrants) and equity-related instruments, the Fund may invest in securities issued in initial public offerings (IPOs), and utilize foreign currency exchange contracts, options, stock index futures contracts, warrants and other derivative instruments. Although the Fund does not expect to invest significantly in derivative instruments during its current fiscal year, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information. Prior to February 1, 2012, the Fund was managed pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy.

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 206%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in securities of companies that are tied economically to countries with emerging securities markets–that is, countries with securities markets which are, in the opinion of the portfolio managers, less sophisticated than more developed markets in terms of participation by investors, analyst coverage, liquidity and regulation. The Fund will normally invest primarily in companies located in the countries represented in the Fund’s benchmark, the MSCI Emerging Markets Index, and have exposure to at least 5 emerging market countries. The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security, industry sector and country selection decisions. The Fund normally invests primarily in common stocks, either directly or indirectly through depositary receipts. The Fund may invest up to 20% of its assets in securities of U.S. companies and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing in common stocks and other equity securities of companies representing a broad range of market capitalizations. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Risk [Heading]

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).

Portfolio Turnover [Text Block]

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 38%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Expense Example Narrative [Text Block]

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 65% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities (such as preferred stocks, convertible securities and warrants) of non-U.S. companies with market capitalizations greater than $1 billion. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The Fund may invest up to 50% of its assets in emerging market securities. The Fund may also achieve its exposure to non-U.S. equity securities through investing in American Depositary Receipts (ADRs). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

Investment Objective

The Fund seeks long-term capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment): None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI U.S. Managed Volatility Fund		Institutional	Class P	Administrative	Class D

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Expense Example AllianzGI U.S. Managed Volatility Fund (USD $)	1 Year	3 Years	5 Years	10 Years

Administrative	91	284	493	1,096
Class D	101	315	547	1,213

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 199%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in equity securities of U.S. companies. The Fund currently defines “U.S. companies” as those companies that (i) are incorporated in the U.S., (ii) derive at least 50% of their revenue or profits from business activities in the U.S. or (iii) maintain at least 50% of their assets in the U.S. The Fund expects to invest typically in companies with market capitalizations at or above the lowest market capitalization of companies represented in the Russell 1000 Index (approximately $1.3 billion as of June 30, 2012). The Fund intends to utilize an investment strategy that focuses on the overall management of portfolio volatility. This focus may result in the Fund outperforming the general securities market during periods of flat or negative market performance, and underperforming the general securities market during periods of strong positive market performance.

The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security and sector selection decisions. Under the Sub-Adviser’s managed volatility strategy, the portfolio managers seek to emphasize stocks that exhibit a lower sensitivity to broader market movements (or “beta”), as they believe that stocks with higher betas are not rewarded with commensurately higher returns by the market. The portfolio construction process is iterative in nature. Initially, the portfolio managers build a fully invested and diversified portfolio subject to sector, capitalization and security constraints with a goal of minimizing total volatility as measured by the standard deviation of returns. The team then overlays a proprietary stock selection model and seeks to build a final portfolio of stocks that considers the trade off between volatility and sources of relative performance (or “alpha”). The portfolio managers consider whether to sell a particular security when any of the above factors materially changes, or when a more attractive investment candidate is available.

In addition to equity securities (such as preferred stocks, convertible securities and warrants) and equity-related instruments, the Fund may invest in securities issued in initial public offerings (IPOs), and utilize foreign currency exchange contracts, options, stock index futures contracts, warrants and other derivative instruments. Although the Fund does not expect to invest significantly in derivative instruments during its current fiscal year, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information. Prior to December 1, 2011, the Fund was managed pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 27%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with large market capitalizations. The Fund currently considers a company’s market capitalization to be large if it equals or exceeds the market capitalization of the 400th largest company represented in the Russell 1000 Index (i.e., a market capitalization of at least approximately $7 billion as of June 30, 2012). The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in securities of companies that are tied economically to countries with emerging securities markets–that is, countries with securities markets which are, in the opinion of the portfolio managers, less sophisticated than more developed markets in terms of participation by investors, analyst coverage, liquidity and regulation. The Fund will normally invest primarily in companies located in the countries represented in the Fund’s benchmark, the MSCI Emerging Markets Index, and have exposure to at least 5 emerging market countries. The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security, industry sector and country selection decisions. The Fund normally invests primarily in common stocks, either directly or indirectly through depositary receipts. The Fund may invest up to 20% of its assets in securities of U.S. companies and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).

Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 199%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in equity securities of U.S. companies. The Fund currently defines “U.S. companies” as those companies that (i) are incorporated in the U.S., (ii) derive at least 50% of their revenue or profits from business activities in the U.S. or (iii) maintain at least 50% of their assets in the U.S. The Fund expects to invest typically in companies with market capitalizations at or above the lowest market capitalization of companies represented in the Russell 1000 Index (approximately $1.3 billion as of June 30, 2012). The Fund intends to utilize an investment strategy that focuses on the overall management of portfolio volatility. This focus may result in the Fund outperforming the general securities market during periods of flat or negative market performance, and underperforming the general securities market during periods of strong positive market performance.

The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security and sector selection decisions. Under the Sub-Adviser’s managed volatility strategy, the portfolio managers seek to emphasize stocks that exhibit a lower sensitivity to broader market movements (or “beta”), as they believe that stocks with higher betas are not rewarded with commensurately higher returns by the market. The portfolio construction process is iterative in nature. Initially, the portfolio managers build a fully invested and diversified portfolio subject to sector, capitalization and security constraints with a goal of minimizing total volatility as measured by the standard deviation of returns. The team then overlays a proprietary stock selection model and seeks to build a final portfolio of stocks that considers the trade off between volatility and sources of relative performance (or “alpha”). The portfolio managers consider whether to sell a particular security when any of the above factors materially changes, or when a more attractive investment candidate is available.

In addition to equity securities (such as preferred stocks, convertible securities and warrants) and equity-related instruments, the Fund may invest in securities issued in initial public offerings (IPOs), and utilize foreign currency exchange contracts, options, stock index futures contracts, warrants and other derivative instruments. Although the Fund does not expect to invest significantly in derivative instruments during its current fiscal year, it may do so at any time.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information. Prior to December 1, 2011, the Fund was managed pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 65% of its assets in common stocks of “growth” companies with market capitalizations of less than $2 billion. The portfolio managers’ investment process focuses on bottom-up, fundamental analysis. The portfolio managers consider “growth” companies to include companies that they believe to have above-average growth prospects (relative to companies in the same industry or the market as a whole). In seeking to identify these companies, the portfolio managers will consider fundamental characteristics such as revenue growth, volume and pricing trends, profit margin behavior, margin expansion opportunities, financial strength, cash flow growth, asset value growth and earnings growth. The investment process includes both quantitative and qualitative analysis. Once a potential investment is identified, the portfolio managers conduct a quantitative analysis to determine if the security is reasonably priced with respect to its peer group on a historical and current basis. Then fundamental research is conducted, focusing on a review of financial statements and third-party research. The portfolio managers seek to diversify the portfolio among different industries. The Fund may invest in securities issued in initial public offerings (IPOs) and up to 15% of its assets in non-U.S. securities (without limit in American Depositary Receipts (ADRs)).

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

AllianzGI NFJ Mid-Cap Value Fund

Investment Objective

The Fund seeks long-term growth of capital and income.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees AllianzGI NFJ Mid-Cap Value Fund		Class A	Class B	Class C	Class R
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)		5.50%	none	none	none
Maximum Contingent Deferred Sales Charge (CDSC) (Load) (as a percentage of the lower of original purchase price or NAV	[1]	1.00%	5.00%	1.00%	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI NFJ Mid-Cap Value Fund	Class A	Class B	Class C	Class R
Management Fees	1.00%	1.00%	1.00%	1.00%
Distribution and/or Service (12b-1) Fees	0.25%	1.00%	1.00%	0.50%
Other Expenses	0.01%	0.01%	0.01%	0.01%
Total Annual Fund Operating Expenses	1.26%	2.01%	2.01%	1.51%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Example: Assuming you redeem your shares at the end of each period

Expense Example AllianzGI NFJ Mid-Cap Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	671	928	1,204	1,989
Class B	704	930	1,283	2,054
Class C	304	630	1,083	2,338
Class R	154	477	824	1,802

Example: Assuming you do not redeem your shares

Expense Example No Redemption AllianzGI NFJ Mid-Cap Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	671	928	1,204	1,989
Class B	204	630	1,083	2,054
Class C	204	630	1,083	2,338
Class R	154	477	824	1,802

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 27%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with medium market capitalizations. The Fund currently defines medium market capitalization companies as those companies with market capitalizations between $2 billion and $17.5 billion. Effective December 1, 2011, consistent with the type of investments suggested by the Fund’s name, the Fund adopted the 80% test referred to above. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest up to 25% of its assets in non-U.S. securities, including emerging market securities (without limit in American Depositary Receipts (ADRs)) and may invest up to 20% of its assets in real estate investment trusts (REITs).

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information. Prior to December 1, 2011, the Fund was managed pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

After-tax returns are for Class A shares only. After-tax returns for other share classes will vary.

[1] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of technology companies and in derivatives and other synthetic instruments that have economic characteristics similar to equity securities of technology companies. Derivatives transactions may have the effect of either magnifying or limiting the Fund’s gains and losses. The Fund normally invests in companies organized or headquartered in at least three different countries and may invest up to 50% of its assets in non-U.S. issuers, including those organized or headquartered in emerging market countries, but normally no more than 25% of its assets are invested in issuers organized or headquartered in any one country outside the United States, other than Japan. The Fund intends to invest primarily in companies with market capitalizations greater than $500 million, with no more than 15% of its assets in technology companies with market capitalizations below $100 million. The Fund is “non-diversified,” which means that it may invest a significant portion of its assets in a relatively small number of issuers, which may increase risk. The portfolio managers define technology companies as those that provide technology products or services or utilize technology to gain competitive advantages. The portfolio managers evaluate fundamental value and growth prospects and focus on companies that they expect will have higher than average rates of growth and strong potential for capital appreciation. The portfolio managers develop forecasts of economic growth, inflation and interest rates that are used to help identify regions and countries that are likely to offer the best investment opportunities. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs) and may utilize foreign currency exchange contracts, options, futures and forward contracts, short sales, swap agreements and other derivative instruments. Although the Fund may invest in derivatives of any kind, it expects to invest in options, swaps and, to a lesser extent, foreign exchange contracts. The Fund may write call options on individual securities that it does not hold in its portfolio (i.e., “naked” call options) as well as call options on indices and exchange-traded funds. The Fund ordinarily expects to use derivative instruments in an attempt to enhance the Fund’s investment returns, to hedge against market and other risks or to obtain market exposure. The Fund may enter into credit default, cross-currency, interest rate, total return, variance and other forms of swap agreements in order to manage its exposure to credit, currency and interest rate risk.

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Focusing on a limited number of issuers, sectors (such as the technology sectors), industries, or geographic regions increases risk and volatility (Focused Investment Risk (Technology-Related Risk)). Derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation (Derivatives Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); Short Selling Risk (short selling enhances leveraging risk and involves counterparty risk and the risk of unlimited loss); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index, a sector-specific index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B and Class C performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes.

Performance Table Not Relevant to Tax Deferred

rr_PerformanceTableNotRelevantToTaxDeferred

Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

Performance Table One Class of after Tax Shown [Text]

rr_PerformanceTableOneClassOfAfterTaxShown

After-tax returns are for Class A shares only. After-tax returns for other share classes will vary.

Performance Table Explanation after Tax Higher

rr_PerformanceTableExplanationAfterTaxHigher

In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 81%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing primarily in equity securities of U.S. companies with market capitalizations of at least $1 billion. The Fund may also invest up to 20% of its assets in non-U.S. securities (but no more than 10% in any one non-U.S. country or 10% in companies organized or headquartered in emerging market countries). At times, depending on market and other conditions, the Fund may also invest a significant percentage of its assets in a small number of business sectors or industries. The portfolio managers are constrained to only including the 25-45 highest conviction large cap growth stocks covered by the research team.

The portfolio managers believe the securities in the Fund exhibit the greatest combination of earnings growth potential, quality (as reflected in consistent business fundamentals) and attractive valuation. The portfolio managers ordinarily look for several of the following characteristics when analyzing specific companies for possible investment: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue, cash flow or earnings through either an expanding market or expanding market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Focusing on a limited number of issuers, sectors, industries, or geographic regions increases risk and volatility (Focused Investment Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Prior to September 24, 2012, the Fund was managed by a different sub-adviser pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

AllianzGI NFJ Small-Cap Value Fund

Investment Objective

The Fund seeks long-term growth of capital and income.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment): None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI NFJ Small-Cap Value Fund		Institutional	Class P	Administrative	Class D

Total Annual Fund Operating Expenses After Expense Reductions	[1]	0.79%	0.94%	1.04%	1.19%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Expense Example AllianzGI NFJ Small-Cap Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional	81	270	474	1,065
Class P	96	306	533	1,187
Administrative	106	348	609	1,356
Class D	121	384	667	1,475

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 26%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with smaller market capitalizations. The Fund currently considers smaller market capitalization companies to be companies with market capitalizations of between $100 million and $3.5 billion. The Fund normally invests significantly in securities of companies that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and non-U.S. securities, including emerging market securities.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Institutional Class shares only. After-tax returns for other share classes will vary.

[1] Effective November 1, 2012, AGIFM has contractually agreed to observe, through October 31, 2013, (i) an irrevocable waiver of a portion of its advisory fees (together with administrative fees paid to AGIFM, a component of "Management Fees"), which reduces the 0.60% contractual fee rate by 0.025% on assets in excess of $3 billion, by an additional 0.025% on assets in excess of $4 billion and by an additional 0.025% on assets in excess of $5 billion, each based on the Fund's average daily net assets, and (ii) an irrevocable waiver of a portion of its administrative fees paid by Institutional and Administrative Class shares, which reduces the 0.30% contractual rate by 0.05% of the Fund's daily net assets attributable to the particular share class. An identical waiver arrangement was in place for the Fund during the whole of its 2011-2012 fiscal year.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 26%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 130%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 65% of its assets in common stocks of “growth” companies with market capitalizations of less than $2 billion. The portfolio managers’ investment process focuses on bottom-up, fundamental analysis. The portfolio managers consider “growth” companies to include companies that they believe to have above-average growth prospects (relative to companies in the same industry or the market as a whole). In seeking to identify these companies, the portfolio managers will consider fundamental characteristics such as revenue growth, volume and pricing trends, profit margin behavior, margin expansion opportunities, financial strength, cash flow growth, asset value growth and earnings growth. The investment process includes both quantitative and qualitative analysis. Once a potential investment is identified, the portfolio managers conduct a quantitative analysis to determine if the security is reasonably priced with respect to its peer group on a historical and current basis. Then fundamental research is conducted, focusing on a review of financial statements and third-party research. The portfolio managers seek to diversify the portfolio among different industries. The Fund may invest in securities issued in initial public offerings (IPOs) and up to 15% of its assets in non-U.S. securities (without limit in American Depositary Receipts (ADRs)).

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in equity securities of companies principally engaged in the research, development, manufacturing, extraction, distribution or sale of materials, energy or goods related to the Agriculture, Energy, Materials or Commodity-Related Industrials sectors. The Fund considers (i) the Agriculture sector to include products such as grain, vegetable oils, livestock and agricultural-type products such as coffee; (ii) the Energy sector to include products such as coal, natural gas, oil, alternative energy and electricity; (iii) the Materials sector to include products such as chemicals & fertilizers, constructions materials, industrial metal, precious metal, steel, minerals and paper products; and (iv) the Commodity-Related Industrials sector to include industrial firms that manufacture tools, equipment and goods used in the development and production of commodities or that maintain infrastructure used in their transportation. The Fund also has a fundamental policy to invest at least 25% of its total assets in the “natural resources” sector, as described in the SAI. Under normal conditions, the portfolio managers seek to allocate investments such that the Fund has exposure to a diverse range of commodities within each of the three primary commodity sectors of Agriculture, Energy and Materials. The Fund expects to invest most of its assets in U.S. and non-U.S. common stocks. Under normal circumstances, the Fund will invest a minimum of 1/3 of its assets in non-U.S. securities and will invest in companies organized or headquartered in at least eight countries including the United States. The Fund may also invest up to 10% of its net assets in securities issued by other investment companies, included exchange-traded funds (“ETFs”).

The Fund’s portfolio managers evaluate the relative attractiveness of individual commodity cycles, including supply-demand fundamentals, pricing outlook and impact on U.S. and non-U.S. macroeconomic indicators like inflation. In addition, the portfolio managers may consider forecasts of economic growth, inflation and interest rates to help identify industry sectors, regions and individual countries (including emerging market countries) that they believe are likely to offer the best investment opportunities. The portfolio managers seek to evaluate the correlation of degree to which companies’ earnings are linked to commodity price changes, as well as companies’ fundamental value and prospects for growth.

In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Focusing on a limited number of issuers, sectors (such as the commodity sectors), industries, or geographic regions increases risk and volatility (Focused Investment Risk (Commodity-Related Companies Risk)). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index, sector-specific custom benchmarks and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

AllianzGI International Managed Volatility Fund

Investment Objective

The Fund seeks maximum long-term capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Example: Assuming you redeem your shares at the end of each period

Expense Example AllianzGI International Managed Volatility Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	643	879	1,135	1,865
Class C	274	581	1,013	2,216
Class R	123	427	752	1,674

Example: Assuming you do not redeem your shares

Expense Example No Redemption AllianzGI International Managed Volatility Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	643	879	1,135	1,865
Class C	174	581	1,013	2,216
Class R	123	427	752	1,674

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 170%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing in a portfolio of international equities that manages overall portfolio volatility. The Fund normally invests primarily in equity securities of companies located outside of the U.S., and will not invest more than 50% of its net assets in companies within any single country. The Fund ordinarily allocates its investments among a number of different countries, including those in the MSCI EAFE Index and normally invests at least 80% of its assets in non-U.S. securities. The Fund normally focuses its non-U.S. investments in developed countries but may also invest in emerging markets securities. The Fund may invest in issuers of any market capitalization, including smaller capitalization companies. The Fund intends to utilize an investment strategy that focuses on the overall management of portfolio volatility. This focus may result in the Fund outperforming the general securities market during periods of flat or negative market performance, and underperforming the general securities market during periods of strong positive market performance.

The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security and sector selection decisions. Under the Sub-Adviser’s managed volatility strategy, the portfolio managers seek to emphasize stocks that exhibit a lower sensitivity to broader market movements (or “beta”), as they believe that stocks with higher betas are not rewarded with commensurately higher returns by the market. The portfolio construction process is iterative in nature. Initially, the portfolio managers build a fully invested and diversified portfolio subject to sector and security constraints with a goal of minimizing total volatility as measured by the standard deviation of returns. The team then overlays a proprietary stock selection model and seeks to build a final portfolio of stocks that considers the trade off between volatility and sources of relative performance (or “alpha”). The portfolio managers consider whether to sell a particular security when any of the above factors materially changes, or when a more attractive investment candidate is available.

In addition to equity securities (such as preferred stocks, convertible securities and warrants) and equity-related instruments, the Fund may invest in securities issued in initial public offerings (IPOs), and utilize foreign currency exchange contracts, options, stock index futures contracts, warrants and other derivative instruments. Although the Fund does not expect to invest significantly in derivative instruments during its current fiscal year, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information. Prior to February 1, 2012, the Fund was managed pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Class A shares only. After-tax returns for other share classes will vary.

[1] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

[1] "Management Fees" reflect the combination of investment advisory fees and administrative fees paid by the Fund to Allianz Global Investors Fund Management LLC ("AGIFM") under separate agreements. Fee rates are based on amounts incurred and fund asset levels during the last fiscal year and, where applicable, advisory fees have been restated to reflect current fee rates.

[2] Effective November 1, 2012, AGIFM has contractually agreed to observe, through October 31, 2013, an irrevocable waiver of a portion of its administrative fees (together with advisory fees paid to AGIFM, a component of "Management Fees"), which reduces the contractual fee rate by 0.20%.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies that pay or are expected to pay dividends. Under normal conditions, the Fund will invest primarily in common stocks of companies with market capitalizations greater than $3.5 billion. The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. In addition, a portion of the securities selected for the Fund are identified primarily on the basis of their dividend yields. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

AllianzGI Emerging Markets Opportunities Fund

Investment Objective

The Fund seeks maximum long-term capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees AllianzGI Emerging Markets Opportunities Fund		Class A	Class C
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)		5.50%	none
Maximum Contingent Deferred Sales Charge (CDSC) (Load) (as a percentage of the lower of original purchase price or NAV	[1]	1.00%	1.00%

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI Emerging Markets Opportunities Fund	Class A	Class C
Management Fees	1.40%	1.40%

Other Expenses	0.04%	0.04%
Total Annual Fund Operating Expenses	1.69%	2.44%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Example: Assuming you redeem your shares at the end of each period

Expense Example AllianzGI Emerging Markets Opportunities Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	712	1,053	1,417	2,438
Class C	347	761	1,301	2,776

Example: Assuming you do not redeem your shares

Expense Example No Redemption AllianzGI Emerging Markets Opportunities Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	712	1,053	1,417	2,438
Class C	247	761	1,301	2,776

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 206%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in securities of companies that are tied economically to countries with emerging securities markets–that is, countries with securities markets which are, in the opinion of the portfolio managers, less sophisticated than more developed markets in terms of participation by investors, analyst coverage, liquidity and regulation. The Fund will normally invest primarily in companies located in the countries represented in the Fund’s benchmark, the MSCI Emerging Markets Index, and have exposure to at least 5 emerging market countries. The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security, industry sector and country selection decisions. The Fund normally invests primarily in common stocks, either directly or indirectly through depositary receipts. The Fund may invest up to 20% of its assets in securities of U.S. companies and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class C performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing primarily in equity securities of U.S. companies with market capitalizations of at least $1 billion. The Fund may also invest up to 20% of its assets in non-U.S. securities (but no more than 10% in any one non-U.S. country or 10% in companies organized or headquartered in emerging market countries). At times, depending on market and other conditions, the Fund may also invest a significant percentage of its assets in a small number of business sectors or industries. The portfolio managers are constrained to only including the 25-45 highest conviction large cap growth stocks covered by the research team.

The portfolio managers believe the securities in the Fund exhibit the greatest combination of earnings growth potential, quality (as reflected in consistent business fundamentals) and attractive valuation. The portfolio managers ordinarily look for several of the following characteristics when analyzing specific companies for possible investment: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue, cash flow or earnings through either an expanding market or expanding market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Focusing on a limited number of issuers, sectors, industries, or geographic regions increases risk and volatility (Focused Investment Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Prior to September 24, 2012, the Fund was managed by a different sub-adviser pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

AllianzGI Global Commodity Equity Fund | AllianzGI Global Commodity Equity Fund

AllianzGI Global Commodity Equity Fund

Investment Objective

The Fund seeks long-term capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment): None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI Global Commodity Equity Fund	Institutional	Class P	Class D
Management Fees	1.05%	1.15%	1.15%
Distribution and/or Service (12b-1) Fees	none	none	0.25%
Other Expenses	0.02%	0.02%	0.02%
Total Fund Operating Expenses	1.07%	1.17%	1.42%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Expense Example AllianzGI Global Commodity Equity Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional	109	340	590	1,306
Class P	119	372	644	1,420
Class D	145	449	776	1,702

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 190%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in equity securities of companies principally engaged in the research, development, manufacturing, extraction, distribution or sale of materials, energy or goods related to the Agriculture, Energy, Materials or Commodity-Related Industrials sectors. The Fund considers (i) the Agriculture sector to include products such as grain, vegetable oils, livestock and agricultural-type products such as coffee; (ii) the Energy sector to include products such as coal, natural gas, oil, alternative energy and electricity; (iii) the Materials sector to include products such as chemicals & fertilizers, constructions materials, industrial metal, precious metal, steel, minerals and paper products; and (iv) the Commodity-Related Industrials sector to include industrial firms that manufacture tools, equipment and goods used in the development and production of commodities or that maintain infrastructure used in their transportation. The Fund also has a fundamental policy to invest at least 25% of its total assets in the “natural resources” sector, as described in the SAI. Under normal conditions, the portfolio managers seek to allocate investments such that the Fund has exposure to a diverse range of commodities within each of the three primary commodity sectors of Agriculture, Energy and Materials. The Fund expects to invest most of its assets in U.S. and non-U.S. common stocks. Under normal circumstances, the Fund will invest a minimum of 1/3 of its assets in non-U.S. securities and will invest in companies organized or headquartered in at least eight countries including the United States. The Fund may also invest up to 10% of its net assets in securities issued by other investment companies, included exchange-traded funds (“ETFs”).

The Fund’s portfolio managers evaluate the relative attractiveness of individual commodity cycles, including supply-demand fundamentals, pricing outlook and impact on U.S. and non-U.S. macroeconomic indicators like inflation. In addition, the portfolio managers may consider forecasts of economic growth, inflation and interest rates to help identify industry sectors, regions and individual countries (including emerging market countries) that they believe are likely to offer the best investment opportunities. The portfolio managers seek to evaluate the correlation of degree to which companies’ earnings are linked to commodity price changes, as well as companies’ fundamental value and prospects for growth.

In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Focusing on a limited number of issuers, sectors (such as the commodity sectors), industries, or geographic regions increases risk and volatility (Focused Investment Risk (Commodity-Related Companies Risk)). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index, sector-specific custom benchmarks and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 36%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing in common stocks and other equity securities of companies representing a broad range of market capitalizations. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in real estate investment trusts (REITs) and in non-U.S. securities, including emerging market securities.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B and Class C performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Class A shares only. After-tax returns for other share classes will vary.

[1] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with smaller market capitalizations. The Fund currently considers smaller market capitalization companies to be companies with market capitalizations of between $100 million and $3.5 billion. The Fund normally invests significantly in securities of companies that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued.

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI.

AllianzGI Technology Fund | AllianzGI Technology Fund

AllianzGI Technology Fund

Investment Objective

The Fund seeks long-term capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment): None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI Technology Fund	Institutional	Class P	Administrative	Class D
Management Fees	1.20%	1.30%	1.20%	1.30%
Distribution and/or Service (12b-1) Fees	none	none	0.25%	0.25%
Other Expenses	0.03%	0.03%	0.03%	0.03%
Total Fund Operating Expenses	1.23%	1.33%	1.48%	1.58%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Expense Example AllianzGI Technology Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional	125	390	676	1,489
Class P	135	421	729	1,601
Administrative	151	468	808	1,768
Class D	161	499	860	1,878

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 176%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of technology companies and in derivatives and other synthetic instruments that have economic characteristics similar to equity securities of technology companies. Derivatives transactions may have the effect of either magnifying or limiting the Fund’s gains and losses. The Fund normally invests in companies organized or headquartered in at least three different countries and may invest up to 50% of its assets in non-U.S. issuers, including those organized or headquartered in emerging market countries, but normally no more than 25% of its assets are invested in issuers organized or headquartered in any one country outside the United States, other than Japan. The Fund intends to invest primarily in companies with market capitalizations greater than $500 million, with no more than 15% of its assets in technology companies with market capitalizations below $100 million. The Fund is “non-diversified,” which means that it may invest a significant portion of its assets in a relatively small number of issuers, which may increase risk. The portfolio managers define technology companies as those that provide technology products or services or utilize technology to gain competitive advantages. The portfolio managers evaluate fundamental value and growth prospects and focus on companies that they expect will have higher than average rates of growth and strong potential for capital appreciation. The portfolio managers develop forecasts of economic growth, inflation and interest rates that are used to help identify regions and countries that are likely to offer the best investment opportunities. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs) and may utilize foreign currency exchange contracts, options, futures and forward contracts, short sales, swap agreements and other derivative instruments. Although the Fund may invest in derivatives of any kind, it expects to invest in options, swaps and, to a lesser extent, foreign exchange contracts. The Fund may write call options on individual securities that it does not hold in its portfolio (i.e., “naked” call options) as well as call options on indices and exchange-traded funds. The Fund ordinarily expects to use derivative instruments in an attempt to enhance the Fund’s investment returns, to hedge against market and other risks or to obtain market exposure. The Fund may enter into credit default, cross-currency, interest rate, total return, variance and other forms of swap agreements in order to manage its exposure to credit, currency and interest rate risk.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Focusing on a limited number of issuers, sectors (such as the technology sectors), industries, or geographic regions increases risk and volatility (Focused Investment Risk (Technology-Related Risk)). Derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation (Derivatives Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); Short Selling Risk (short selling enhances leveraging risk and involves counterparty risk and the risk of unlimited loss); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index, a sector-specific index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.

AllianzGI Income & Growth Fund

Investment Objective

The Fund seeks total return comprised of current income, current gains and capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment): None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI Income & Growth Fund	Institutional Class	Class P	Class D
Management Fees	0.95%	1.05%	1.05%
Distribution and/or Service (12b-1) Fees	none	none	0.25%
Other Expenses	0.01%	0.01%	0.01%
Total Fund Operating Expenses	0.96%	1.06%	1.31%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Expense Example AllianzGI Income & Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional Class	98	306	531	1,178
Class P	108	337	585	1,294
Class D	133	415	718	1,579

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 129%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by investing primarily in a combination of common stocks and other equity securities, debt securities and convertible securities. The allocation of the Fund’s investments across asset classes will vary substantially from time to time. The Fund’s investments in each asset class are based upon the portfolio managers’ assessment of economic conditions and market factors, including equity price levels, interest rate levels and their anticipated direction. The portfolio managers will select common stocks by utilizing a fundamental, bottom-up research process intended to identify issuers whose financial fundamentals are expected to improve, and will select convertible or debt securities using a credit analysis that focuses on income producing characteristics. It is expected that a substantial portion of the Fund’s investments in debt securities and convertible securities will be rated below investment grade or unrated and determined to be of similar quality (“high-yield securities” or “junk bonds”). The Fund may invest in issuers of any market capitalization (with a focus on $3 billion and above) and may invest a portion of its assets in non-U.S. securities (including emerging market securities). Normally the Fund will employ a strategy of writing (selling) call options on the common stocks it holds; such strategy is intended to enhance Fund distributions and reduce overall portfolio risk, though there is no assurance that it will succeed. In addition to equity securities (such as preferred stocks and warrants), the Fund may invest in unregistered securities and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation (Derivatives Risk). Convertible and debt securities, particularly high-yield or junk bonds, are subject to greater levels of credit and liquidity risk, may be speculative and may decline in value due to changes in interest rates or an issuer’s deterioration or default (High Yield Risk, Convertible Securities Risk, Interest Rate Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Strategy Narrative [Text Block]

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of medium-sized companies. The Fund currently defines medium-sized companies as those having market capitalizations comparable to those companies included in the Russell Midcap Growth Index (between $1.3 billion and $19.1 billion as of June 30, 2012). The Fund normally invests primarily in equity securities of U.S. companies. The portfolio managers ordinarily look for companies with the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs) and in non-U.S. securities, and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Portfolio Turnover [Text Block]

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 206%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in securities of companies that are tied economically to countries with emerging securities markets–that is, countries with securities markets which are, in the opinion of the portfolio managers, less sophisticated than more developed markets in terms of participation by investors, analyst coverage, liquidity and regulation. The Fund will normally invest primarily in companies located in the countries represented in the Fund’s benchmark, the MSCI Emerging Markets Index, and have exposure to at least 5 emerging market countries. The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security, industry sector and country selection decisions. The Fund normally invests primarily in common stocks, either directly or indirectly through depositary receipts. The Fund may invest up to 20% of its assets in securities of U.S. companies and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class C performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in wellness-related companies. The Fund may invest in U.S. and non-U.S. companies, and currently expects the majority of its non-U.S. investments will normally be in Asia and Western Europe. The Fund may invest up to 15% of its assets in companies organized or headquartered in emerging market countries (but no more than 10% in any one emerging market country). The Fund will invest primarily in common stocks and other equity securities. Although the Fund may invest in companies of any market capitalization, the Fund does not intend to invest more than 15% of its assets in companies with market capitalizations below $100 million. The portfolio managers consider wellness-related companies to include companies in the healthcare industry and other companies that provide products or services that promote or aid in achieving a healthy lifestyle. The portfolio managers develop forecasts of economic growth, inflation and interest rates that are used to help identify regions and countries that are likely to offer the best investment opportunities. The portfolio managers may consider the anticipated economic growth rate, political outlook, inflation rate, currency outlook and interest rate environment for the country and the region in which a company is located. The portfolio managers ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through either an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. The Fund is “non-diversified,” which means that it may invest a significant portion of its assets in a relatively small number of issuers, which may increase risk. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs), and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund may invest in derivatives of any kind, it expects to write (sell) put and call options on securities for hedging, risk management or other purposes.

Risk Narrative [Text Block]

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Focusing on a limited number of issuers, sectors (such as the wellness sector), industries, or geographic regions increases risk and volatility (Focused Investment Risk (Wellness-Related Risk)). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index, a sector-specific custom benchmark and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B and Class C performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 46%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of U.S. companies with market capitalizations of at least $5 billion. The Fund may also invest up to 20% of its assets in non-U.S. securities (but no more than 10% in any one non-U.S. country or 10% in companies organized or headquartered in emerging market countries). At times, the Fund may also invest significantly in a small number of business sectors or industries. In analyzing specific companies, the portfolio managers ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue, cash flow or earnings through an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

AllianzGI Technology Fund

Investment Objective

The Fund seeks long-term capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees AllianzGI Technology Fund		Class A	Class B	Class C
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)		5.50%	none	none
Maximum Contingent Deferred Sales Charge (CDSC) (Load) (as a percentage of the lower of original purchase price or NAV	[1]	1.00%	5.00%	1.00%

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI Technology Fund	Class A	Class B	Class C
Management Fees	1.30%	1.30%	1.30%
Distribution and/or Service (12b-1) Fees	0.25%	1.00%	1.00%

Total Annual Fund Operating Expenses	1.58%	2.33%	2.33%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Example: Assuming you redeem your shares at the end of each period

Expense Example AllianzGI Technology Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	702	1,021	1,363	2,325
Class B	736	1,027	1,445	2,391
Class C	336	727	1,245	2,666

Example: Assuming you do not redeem your shares

Expense Example No Redemption AllianzGI Technology Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	702	1,021	1,363	2,325
Class B	236	727	1,245	2,391
Class C	236	727	1,245	2,666

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 176%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of technology companies and in derivatives and other synthetic instruments that have economic characteristics similar to equity securities of technology companies. Derivatives transactions may have the effect of either magnifying or limiting the Fund’s gains and losses. The Fund normally invests in companies organized or headquartered in at least three different countries and may invest up to 50% of its assets in non-U.S. issuers, including those organized or headquartered in emerging market countries, but normally no more than 25% of its assets are invested in issuers organized or headquartered in any one country outside the United States, other than Japan. The Fund intends to invest primarily in companies with market capitalizations greater than $500 million, with no more than 15% of its assets in technology companies with market capitalizations below $100 million. The Fund is “non-diversified,” which means that it may invest a significant portion of its assets in a relatively small number of issuers, which may increase risk. The portfolio managers define technology companies as those that provide technology products or services or utilize technology to gain competitive advantages. The portfolio managers evaluate fundamental value and growth prospects and focus on companies that they expect will have higher than average rates of growth and strong potential for capital appreciation. The portfolio managers develop forecasts of economic growth, inflation and interest rates that are used to help identify regions and countries that are likely to offer the best investment opportunities. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs) and may utilize foreign currency exchange contracts, options, futures and forward contracts, short sales, swap agreements and other derivative instruments. Although the Fund may invest in derivatives of any kind, it expects to invest in options, swaps and, to a lesser extent, foreign exchange contracts. The Fund may write call options on individual securities that it does not hold in its portfolio (i.e., “naked” call options) as well as call options on indices and exchange-traded funds. The Fund ordinarily expects to use derivative instruments in an attempt to enhance the Fund’s investment returns, to hedge against market and other risks or to obtain market exposure. The Fund may enter into credit default, cross-currency, interest rate, total return, variance and other forms of swap agreements in order to manage its exposure to credit, currency and interest rate risk.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Focusing on a limited number of issuers, sectors (such as the technology sectors), industries, or geographic regions increases risk and volatility (Focused Investment Risk (Technology-Related Risk)). Derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation (Derivatives Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); Short Selling Risk (short selling enhances leveraging risk and involves counterparty risk and the risk of unlimited loss); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index, a sector-specific index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B and Class C performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Class A shares only. After-tax returns for other share classes will vary.

[1] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with medium market capitalizations. The Fund currently defines medium market capitalization companies as those companies with market capitalizations between $2 billion and $17.5 billion. Effective December 1, 2011, consistent with the type of investments suggested by the Fund’s name, the Fund adopted the 80% test referred to above. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest up to 25% of its assets in non-U.S. securities, including emerging market securities (without limit in American Depositary Receipts (ADRs)) and may invest up to 20% of its assets in real estate investment trusts (REITs).

AllianzGI Global Commodity Equity Fund

Investment Objective

The Fund seeks long-term capital appreciation.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 110 of the Fund’s statutory prospectus or from your financial advisor.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees AllianzGI Global Commodity Equity Fund		Class A	Class C

Maximum Contingent Deferred Sales Charge (CDSC) (Load) (as a percentage of the lower of original purchase price or NAV	[1]	1.00%	1.00%

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AllianzGI Global Commodity Equity Fund	Class A	Class C
Management Fees	1.15%	1.15%

Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Example: Assuming you redeem your shares at the end of each period

Expense Example AllianzGI Global Commodity Equity Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	687	975	1,284	2,158
Class C	320	679	1,164	2,503

Example: Assuming you do not redeem your shares

Expense Example No Redemption AllianzGI Global Commodity Equity Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	687	975	1,284	2,158
Class C	220	679	1,164	2,503

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 190%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in equity securities of companies principally engaged in the research, development, manufacturing, extraction, distribution or sale of materials, energy or goods related to the Agriculture, Energy, Materials or Commodity-Related Industrials sectors. The Fund considers (i) the Agriculture sector to include products such as grain, vegetable oils, livestock and agricultural-type products such as coffee; (ii) the Energy sector to include products such as coal, natural gas, oil, alternative energy and electricity; (iii) the Materials sector to include products such as chemicals & fertilizers, constructions materials, industrial metal, precious metal, steel, minerals and paper products; and (iv) the Commodity-Related Industrials sector to include industrial firms that manufacture tools, equipment and goods used in the development and production of commodities or that maintain infrastructure used in their transportation. The Fund also has a fundamental policy to invest at least 25% of its total assets in the “natural resources” sector, as described in the SAI. Under normal conditions, the portfolio managers seek to allocate investments such that the Fund has exposure to a diverse range of commodities within each of the three primary commodity sectors of Agriculture, Energy and Materials. The Fund expects to invest most of its assets in U.S. and non-U.S. common stocks. Under normal circumstances, the Fund will invest a minimum of 1/3 of its assets in non-U.S. securities and will invest in companies organized or headquartered in at least eight countries including the United States. The Fund may also invest up to 10% of its net assets in securities issued by other investment companies, included exchange-traded funds (“ETFs”).

The Fund’s portfolio managers evaluate the relative attractiveness of individual commodity cycles, including supply-demand fundamentals, pricing outlook and impact on U.S. and non-U.S. macroeconomic indicators like inflation. In addition, the portfolio managers may consider forecasts of economic growth, inflation and interest rates to help identify industry sectors, regions and individual countries (including emerging market countries) that they believe are likely to offer the best investment opportunities. The portfolio managers seek to evaluate the correlation of degree to which companies’ earnings are linked to commodity price changes, as well as companies’ fundamental value and prospects for growth.

In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Focusing on a limited number of issuers, sectors (such as the commodity sectors), industries, or geographic regions increases risk and volatility (Focused Investment Risk (Commodity-Related Companies Risk)). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index, sector-specific custom benchmarks and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class C performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 27%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with medium market capitalizations. The Fund currently defines medium market capitalization companies as those companies with market capitalizations between $2 billion and $17.5 billion. Effective December 1, 2011, consistent with the type of investments suggested by the Fund’s name, the Fund adopted the 80% test referred to above. The Fund normally invests significantly in securities that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe are undervalued. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be undervalued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use quantitative factors to screen the Fund’s selection universe, analyzing factors such as price momentum (i.e., changes in security price relative to changes in overall market prices), earnings estimate revisions (i.e., changes in analysts’ earnings-per-share estimates) and fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest up to 25% of its assets in non-U.S. securities, including emerging market securities (without limit in American Depositary Receipts (ADRs)) and may invest up to 20% of its assets in real estate investment trusts (REITs).

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); REIT Risk (adverse changes in the real estate markets may affect the value of REIT investments); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information. Prior to December 1, 2011, the Fund was managed pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Institutional Class shares only. After-tax returns for other share classes will vary.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 170%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing in a portfolio of international equities that manages overall portfolio volatility. The Fund normally invests primarily in equity securities of companies located outside of the U.S., and will not invest more than 50% of its net assets in companies within any single country. The Fund ordinarily allocates its investments among a number of different countries, including those in the MSCI EAFE Index and normally invests at least 80% of its assets in non-U.S. securities. The Fund normally focuses its non-U.S. investments in developed countries but may also invest in emerging markets securities. The Fund may invest in issuers of any market capitalization, including smaller capitalization companies. The Fund intends to utilize an investment strategy that focuses on the overall management of portfolio volatility. This focus may result in the Fund outperforming the general securities market during periods of flat or negative market performance, and underperforming the general securities market during periods of strong positive market performance.

The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security and sector selection decisions. Under the Sub-Adviser’s managed volatility strategy, the portfolio managers seek to emphasize stocks that exhibit a lower sensitivity to broader market movements (or “beta”), as they believe that stocks with higher betas are not rewarded with commensurately higher returns by the market. The portfolio construction process is iterative in nature. Initially, the portfolio managers build a fully invested and diversified portfolio subject to sector and security constraints with a goal of minimizing total volatility as measured by the standard deviation of returns. The team then overlays a proprietary stock selection model and seeks to build a final portfolio of stocks that considers the trade off between volatility and sources of relative performance (or “alpha”). The portfolio managers consider whether to sell a particular security when any of the above factors materially changes, or when a more attractive investment candidate is available.

In addition to equity securities (such as preferred stocks, convertible securities and warrants) and equity-related instruments, the Fund may invest in securities issued in initial public offerings (IPOs), and utilize foreign currency exchange contracts, options, stock index futures contracts, warrants and other derivative instruments. Although the Fund does not expect to invest significantly in derivative instruments during its current fiscal year, it may do so at any time.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. The Examples also assume conversion of Class B shares to Class A shares after seven years. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Example: Assuming you redeem your shares at the end of each period

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 130%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 65% of its assets in common stocks of “growth” companies with market capitalizations of less than $2 billion. The portfolio managers’ investment process focuses on bottom-up, fundamental analysis. The portfolio managers consider “growth” companies to include companies that they believe to have above-average growth prospects (relative to companies in the same industry or the market as a whole). In seeking to identify these companies, the portfolio managers will consider fundamental characteristics such as revenue growth, volume and pricing trends, profit margin behavior, margin expansion opportunities, financial strength, cash flow growth, asset value growth and earnings growth. The investment process includes both quantitative and qualitative analysis. Once a potential investment is identified, the portfolio managers conduct a quantitative analysis to determine if the security is reasonably priced with respect to its peer group on a historical and current basis. Then fundamental research is conducted, focusing on a review of financial statements and third-party research. The portfolio managers seek to diversify the portfolio among different industries. The Fund may invest in securities issued in initial public offerings (IPOs) and up to 15% of its assets in non-U.S. securities (without limit in American Depositary Receipts (ADRs)).

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance). Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Class B, Class C and Class R performance would be lower than Class A performance because of the lower expenses paid by Class A shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit www.allianzinvestors.com for more current performance information.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.

[1] For Class A shares, the CDSC is imposed only in certain circumstances where shares are purchased without a front-end sales charge at the time of purchase. For Class B shares, the maximum CDSC is imposed on shares redeemed in the first year, with CDSCs decreasing over time to zero for shares held longer. For Class C shares, the CDSC is imposed only on shares redeemed in the first year.

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 46%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of U.S. companies with market capitalizations of at least $5 billion. The Fund may also invest up to 20% of its assets in non-U.S. securities (but no more than 10% in any one non-U.S. country or 10% in companies organized or headquartered in emerging market countries). At times, the Fund may also invest significantly in a small number of business sectors or industries. In analyzing specific companies, the portfolio managers ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue, cash flow or earnings through an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer (Equity Securities Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk (non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of two broad-based market indexes and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. Similarly, for periods prior to a reorganization of the Fund, in which a predecessor fund was merged into the Fund, the performance information is based on the performance of the predecessor fund, adjusted to reflect certain fees and expenses paid by the particular share class of the Fund. These adjustments generally result in estimated performance results that are higher or lower than the actual results of the predecessor class and/or the predecessor fund, as the case may be, due to differing levels of fees and expenses paid.

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2012 was 80%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in companies with market capitalizations comparable to those of companies included in the MSCI World Small-Cap Index (between $11.4 million and $5.6 billion as of June 30, 2012). Under normal market and other conditions, the Fund expects to maintain a weighted-average market capitalization between 50% and 200% of the weighted-average market capitalization of the securities in the MSCI World Small-Cap Index, which as of June 30, 2012 would permit the Fund to maintain a weighted-average market capitalization ranging from $929 million to $3.7 billion. The Fund normally invests in companies organized or headquartered in at least eight different countries (one of which may be the United States) and expects that the majority of its non-U.S. investments will normally be in Japan and Western Europe. The Fund will normally invest no more than 25% of its assets in issuers that are organized or headquartered in any one country outside the U.S., other than France, Germany, Japan and the United Kingdom. The Fund may invest up to 30% of its assets in companies organized or headquartered in emerging market countries (but no more than 10% in any one emerging market country). Regional portfolio managers in the United States, Europe and Asia collaborate to produce a portfolio that is believed likely to have the best investment opportunities from each of those regions. The allocation of Fund assets among these three regions is set from time to time and periodically adjusted through a collaborative effort among the most senior portfolio manager in the regions.

The portfolio managers in Europe and Asia develop forecasts of economic growth, inflation and interest rates that are used to help identify countries and other geographies within the applicable region that are likely to offer the best investment opportunities. The portfolio managers may consider the anticipated economic growth rate, political outlook, inflation rate, currency outlook and interest rate environment for the country and the region in which a company is located. The portfolio managers in Europe and Asia ordinarily look for the following characteristics: higher than average growth and strong potential for capital appreciation; substantial capacity for growth in revenue through either an expanding market or market share; a strong balance sheet; superior management; strong commitment to research and product development; and differentiated or superior products and services or a steady stream of new products and services.

The portfolio managers in the United States follow a disciplined, fundamental bottom-up research process focusing on North American companies with sustainable growth characteristics that are undergoing positive fundamental change. The portfolio managers look for what they believe to be the best risk-reward candidates within the investment universe, defined as equities that are expected to appreciate based on accelerating fundamental performance, rising expectations and related multiple expansion. Company-specific research includes industry and competitive analysis, revenue model analysis, profit analysis and balance sheet assessment. Once the portfolio managers in the United States believe that positive fundamental change is occurring and will likely lead to accelerating fundamental performance, they seek evidence that performance will be a longer-term sustainable trend. Lastly, these portfolio managers determine if the investment is timely with regard to relative valuation and price strength, exploiting stocks that are under-priced relative to their potential.

In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest in securities issued in initial public offerings (IPOs), and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The Fund’s net asset value, yield and total return will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management, factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers, and factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them (Management Risk, Issuer Risk, Market Risk). Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer, and securities issued by smaller companies may be more volatile and present increased liquidity risk (Equity Securities Risk, Smaller Company Risk). Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets, and non-U.S. securities values may also fluctuate with currency exchange rates (Non-U.S. Investment Risk, Emerging Markets Risk, Currency Risk). Other principal risks include: Credit Risk (an issuer or counterparty may default on obligations); Derivatives Risk (derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation); Focused Investment Risk (focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility); IPO Risk (securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility); Leveraging Risk (instruments and transactions that constitute leverage magnify gains or losses and increase volatility); Liquidity Risk (the lack of an active market for investments may cause delay in disposition or force a sale below fair value); and Turnover Risk (high levels of portfolio turnover increase transaction costs and taxes and may lower investment performance).
