EXPENSE EXAMPLE

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Sold

Expense Example - (John Hancock Tax-Free Bond Fund) - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	480	672	880	1,477
Class B	660	817	1,098	1,768
Class C	260	517	898	1,968

Not Sold

Expense Example, No Redemption - (John Hancock Tax-Free Bond Fund) - USD ($)	1 Year	3 Years	5 Years	10 Years
Class B	160	517	898	1,768
Class C	160	517	898	1,968

PORTFOLIO TURNOVER

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 13% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the fund invests at least 80% of its net assets, plus amounts borrowed for investment purposes, in tax-exempt bonds of any maturity. Most of these bonds are investment grade when purchased, but the fund may also invest up to 35% of its net assets in junk bonds rated BB or B by S&P or Fitch or Ba or B by Moody's or their unrated equivalents. Bonds that are rated at or below BB by Standard & Poor's Ratings Services (S&P) or Fitch Ratings, Inc. (Fitch) or Ba by Moody's Investors Service, Inc. (Moody's) are considered junk bonds. The fund's investment policies are based on credit ratings at the time of purchase.

The fund may buy bonds of any maturity. The fund may invest heavily in bonds from any given state or region, and currently has substantial investments in obligations of Massachusetts and New York and their agencies, instrumentalities, and/or political subdivisions. The fund may invest in derivatives. Derivatives may be used to reduce risk and/or enhance investment return, and may include futures contracts on debt securities and debt securities indexes; options on futures, debt securities, and debt indexes; and inverse floating-rate securities. The manager looks for undervalued bonds, based on both broad and security-specific factors, such as issuer creditworthiness, bond structure, and general credit trends. The manager uses detailed analysis of an appropriate index to model anticipated portfolio performance and composition and then blends the macro assessment with security analysis. The fund does not intend to engage in frequent trading.

In general, the manager favors bonds backed by revenue from a specific public project or facility, such as a power plant (revenue bonds), as they tend to offer higher yields than general obligation bonds. The manager also favors bonds that have limitations on early payoff (call protection), which can help minimize the potential effect of falling interest rates on the fund's yield. To the extent that the fund invests in bonds that are subject to the alternative minimum tax (AMT), the income paid by the fund may not be entirely tax-free to all investors. Investments in bonds subject to the AMT will not be counted toward the fund's 80% investment policy.

PRINCIPAL RISKS

An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.

During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.

The fund's main risks are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

Changing distribution levels risk. The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.

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 fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.

Cybersecurity risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance.

Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.

Fixed-income securities risk. A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.

Hedging, derivatives, and other strategic transactions risk. Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Derivatives and other strategic transactions that the fund intends to utilize, along with specific additional associated risks, if any, include: futures contracts; inverse floating-rate securities; and options. Futures contracts and options generally are subject to counterparty risk.

Liquidity risk. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact their price or salability. The secondary market for certain tax-exempt securities tends to be less well-developed or liquid than many other securities markets, which may result in increased volatility or liquidity risk.

Lower-rated and high-yield fixed-income securities risk. Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.

Municipal bond risk. Municipal bond prices can decline if the issuer's credit quality declines. Revenue bond prices can decline if related projects become unprofitable. An insured municipal bond is subject to the risk that the insurer may be unable to pay claims and is not insured with respect to the market value of the obligation. Municipal bond income could become taxable in the future.

Sector risk. When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.

State/region risk. Investing heavily in any one state or region increases exposure to losses in that state or region. Factors that may affect performance include economic or political changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in credit ratings. Puerto Rican municipal obligations, in which the fund may invest, may be subject to further devaluation due to adverse political, economic, and market conditions. Because the fund has substantial investments in obligations of Massachusetts and New York, and their agencies, instrumentalities, and/or political subdivisions, its performance also will be affected by risk factors specific to those states.
