(Core Strategy Trust)

Investment Objective

Seeks long term growth of capital. Current income is also a consideration.

Fees and Expenses

This table describes the fees and expenses that you may pay if shares of the fund are held by separate accounts of certain John Hancock insurance companies that fund variable annuity and variable life insurance contracts. They are based on expenses incurred during the fund's most recent fiscal year expressed as a percentage of the fund's average net assets during the year. In subsequent periods, the fund's expense ratio may increase due to decreases in fund assets attributable to redemptions and declines in portfolio valuation. The fees and expenses do not reflect fees and expenses of any separate account that may use the fund as its underlying investment medium and would be higher if they did.

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

Annual Fund Operating Expenses (Core Strategy Trust)		Series I	Series II	NAV
Management fee		0.05%	0.05%	0.05%
Distribution and service (12b-1) fees		0.05%	0.25%	none
Other Expenses		0.03%	0.03%	0.03%
Acquired fund fees and expenses	[1]	0.50%	0.50%	0.50%
Total annual fund operating expenses		0.63%	0.83%	0.58%

Examples. The examples are intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The examples assume that $10,000 is invested in the fund for the periods indicated and then all shares are redeemed at the end of those periods. The examples also assume that the investment has a 5% return each year and that the fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (Core Strategy Trust) (USD $)	1 Year	3 Years	5 Years	10 Years
Series I	64	202	351	786
Series II	85	265	460	1,025
NAV	59	186	324	726

Portfolio Turnover

The fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or "turns over" its portfolio). An underlying fund does pay transaction costs when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the underlying funds and of the fund. During its most recent fiscal year, the fund's portfolio turnover rate was 110% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the fund invests in other funds of JHVIT and other investment companies (including exchange traded funds) (Underlying Funds") as well as other types of investments, See "Other Permitted Investments by the Funds of Funds." The fund invests approximately 70% of its total assets in equity securities and Underlying Funds which invest primarily in equity securities ("Equity Investments") and approximately 30% of its total assets in fixed income securities and Underlying Funds which invest primarily in fixed income securities ("Fixed Income Investments").

The fund may also invest in various Underlying Funds that as a group hold a wide range of equity type securities in their portfolios. These include small-, mid- and large-capitalization stocks, domestic and foreign securities (including emerging market securities) and sector holdings such as utilities and science and technology stocks. Each of the Underlying Funds has its own investment strategy which, for example, may focus on growth stocks or value stocks or may employ a strategy combining growth and income stocks and/or may invest in derivatives such as options on securities and futures contracts. Certain of the Underlying Funds in which the fund invests focus their investment strategy on fixed-income securities, which may include investment grade and below investment grade debt securities with maturities that range from short to longer term. The fixed-income Underlying Funds collectively hold various types of debt instruments such as corporate bonds and mortgage backed, government issued, domestic and international securities.

Variations in the target percentage allocations between Equity Investments and Fixed Income Investments are permitted up to 10% in either direction. For example, based on its investment allocation of approximately 70% of assets in Equity Investments and 30% of assets in Fixed Income Investments, the fund may have an equity/fixed income allocation of 80%/20% or 60%/40%. Variations beyond the permissible deviation range of 10% are not permitted except that, in light of market or economic conditions, the subadvisor may determine that the normal percentage limitations should be exceeded to protect the fund or to achieve the fund's objective.

The fund is monitored daily. To maintain target allocations in the Underlying Funds, daily cash flow for the fund will be directed to the Underlying Fund that most deviates from target. Quarterly, the subadvisor may also rebalance the fund's Underlying Funds to maintain target allocations. The subadvisor may from time to time adjust the percent of assets invested in any specific Underlying Fund held by the fund. Such adjustments may be made to increase or decrease the fund's holdings of particular asset classes, such as common stocks of foreign issuers, or to adjust portfolio quality or the duration of fixed income securities. Adjustments may also be made to increase or reduce the percent of the fund's assets subject to the management of a particular Underlying Fund subadvisor. In addition, changes may be made to reflect fundamental changes in the investment environment.

The fund may also invest in the securities of other investment companies including exchange traded funds (ETFs) and may invest directly in other type of investments, such as equity and fixed-income securities including U.S. government securities, closed-end funds and partnerships. See "Other Permitted Investments by the Funds of Funds." The fund may also engage in short selling.

The investment performance of the fund will reflect both its subadvisor's allocation decisions with respect to Underlying Funds and the investment decisions made by the Underlying Funds' subadvisors. The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the Underlying Funds in which it invests.

When purchasing shares of other JHVIT funds, the fund only purchases Class NAV shares (which are not subject to Rule 12b-1 fees).

Use of Hedging and Other Strategic Transactions. The fund is authorized to use all of the various investment strategies referred to under "Additional Information About the Funds' Principal Risks - Hedging, derivatives and other strategic trans actions risk" including, without limitation, investing in credit default swaps, foreign currency forward contracts, futures contracts, interest rate swaps and options.

Principal Risks of Investing in the Fund of Funds

The Fund of Funds is subject to risks, and you could lose money by investing in the fund. The principal risks of investing in the Fund of Funds include:

Active management risk The subadvisor's investment strategy may fail to produce the intended result.

Fund of funds risk The fund is subject to the performance of the underlying funds in which it invests.

Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. In addition, the use of derivative instruments (such as options, futures and swaps) could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price. The following is a list of certain derivatives and other strategic transactions in which the fund may invest and the main risks associated with each of them:

Credit default swaps Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), interest-rate risk, risk of default of the underlying reference obligation and risk of disproportionate loss are the principal risks of engaging in transactions involving credit default swaps.

Foreign currency forward contracts Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), foreign currency risk and risk of disproportionate loss are the principal risks of engaging in transactions involving foreign currency forward contracts.

Futures contracts Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions) and risk of disproportionate loss are the principal risks of engaging in transactions involving futures contracts.

Interest-rate swaps Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), interest-rate risk and risk of disproportionate loss are the principal risks of engaging in transactions involving interest-rate swaps.

Options Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions) and risk of disproportionate loss are the principal risks of engaging in transactions involving options. Counterparty risk does not apply to exchange-traded options.

Investment company securities risk The fund bears its own expenses and indirectly bears its proportionate share of expenses of the underlying funds in which it invests.

Principal Risks of Investing in the Underlying Funds

The principal risks of investing in the Underlying Funds include:

Active management risk The subadvisor's investment strategy may fail to produce the intended result.

Convertible securities risk The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. In addition, as the market price of the underlying common stock declines below the conversion price, the price of the convertible security tends to be increasingly influenced more by the yield of the convertible security.

Credit and counterparty risk The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract or a borrower of a fund's securities may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations. Funds that invest in fixed-income securities are subject to varying degrees of risk that the issuers of the securities will have their credit rating downgraded or will default, potentially reducing a fund's share price and income level.

Emerging markets risk The risks of investing in foreign securities are greater for investments in emerging markets. Emerging market countries may experience higher inflation, interest rates and unemployment as well as greater social, economic, regulatory and political uncertainties than more developed countries.

Equity securities risk The value of a company's equity securities is subject to changes in the company's financial condition, and overall market and economic conditions.

Fixed-income securities risk Fixed-income securities are affected by changes in interest rates and credit quality. A rise in interest rates typically causes bond prices to fall. The longer the average maturity of the bonds held by the fund, the more sensitive the fund is likely to be to interest-rate changes. There is the possibility that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments.

Foreign securities risk As compared to U.S. companies, there may be less publicly available information relating to foreign companies. Foreign securities may be subject to foreign taxes. The value of foreign securities is subject to currency fluctuations and adverse political and economic developments.

Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. The use of derivative instruments could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price. The following is a list of certain derivatives and other strategic transactions in which the fund may invest and the main risks associated with each of them:

Credit default swaps Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), interest-rate risk, risk of default of the underlying reference obligation and risk of disproportionate loss are the principal risks of engaging in transactions involving credit default swaps.

Foreign currency forward contracts Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), foreign currency risk and risk of disproportionate loss are the principal risks of engaging in transactions involving foreign currency forward contracts.

Futures contracts Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions) and risk of disproportionate loss are the principal risks of engaging in transactions involving futures contracts.

Interest-rate swaps Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), interest-rate risk and risk of disproportionate loss are the principal risks of engaging in transactions involving interest-rate swaps.

Options Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions) and risk of disproportionate loss are the principal risks of engaging in transactions involving options. Counterparty risk does not apply to exchange-traded options.

High portfolio turnover risk Actively trading securities can increase transaction costs (thus lowering performance).

Index management risk Certain factors may cause a fund that is an index fund to track its target index less closely. For example, a subadvisor may select securities that are not fully representative of the index, and the fund's transaction expenses, and the size and timing of its cash flows, may result in the fund's performance being different than that of its index. Moreover, the fund will generally reflect the performance of its target index even when the index does not perform well.

Industry or sector investing risk The performance of a fund that focuses on a single industry or sector of the economy depends in large part on the performance of that industry or sector. As a result, the value of an investment may fluctuate more widely than it would in a fund that is diversified across industries or sectors.

Initial public offerings risk IPO shares may have a magnified impact on fund performance and are frequently volatile in price. They can be held for a short period of time causing an increase in portfolio turnover.

Issuer risk An issuer of a security may perform poorly and, therefore, the value of its stocks and bonds may decline. An issuer of securities held by the fund could default or have its credit rating downgraded.

Liquidity risk Exposure exists when trading volume, lack of a market maker or legal restrictions impair the ability to sell particular securities or close derivative positions at an advantageous price.

Lower-rated Fixed-income securities risk and high-yield securities risk Lower-rated fixed-income securities and high-yield fixed-income securities (commonly known as "junk bonds") are subject to greater credit quality risk and risk of default than higher-rated fixed-income securities. These securities may be considered speculative and the value of these securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market or economic developments and can be difficult to resell.

Medium and smaller company risk The prices of medium and smaller company stocks can change more frequently and dramatically than those of large company stocks. For purposes of the fund's investment policies, the market capitalization of a company is based on its market capitalization at the time the fund purchases the company's securities. Market capitalizations of companies change over time.

Mortgage-backed and asset-backed securities risk Different types of mortgage-backed securities and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate and/or other market risks.

Short sales risk Short sales involve costs and risk. The fund must pay the lender interest on the security it borrows, and the fund will lose money if the price of the security increases between the time of the short sale and the date when the fund replaces the borrowed security.

Past Performance

The following information provides some indication of the risks of investing in the fund by showing changes in performance from year to year and by showing how average annual returns for specified periods compare with those of a broad measure of market performance. Unless all share classes shown in the table have the same inception date, performance shown for periods prior to the inception date of a class is the performance of the fund's oldest share class. This pre-inception performance, with respect to any other share class of the fund, has not been adjusted to reflect the 12b-1 fees of that class. As a result, the pre-inception performance shown for a share class other than the oldest share class may be higher or lower than it would be if adjusted to reflect the 12b-1 fees of the class. The performance information below does not reflect fees and expenses of any variable insurance contract which may use JHVIT as its underlying investment medium. If such fees and expenses had been reflected, performance would be lower. The past performance of the fund is not necessarily an indication of how the fund will perform in the future.
