                               CHAIRMAN'S MESSAGE

DEAR FELLOW SHAREHOLDERS:

[A 1 1/4" x 1" photo of Edward J. Boudreau Jr., Chairman and Chief Executive
Officer, flush right, next to second paragraph.]

Educating shareholders has always been one of the most important
responsibilities of a mutual fund company. But that challenge has taken on new
significance in the past several years. Looking at the most recent statistics,
you can see why. According to the Investment Company Institute, the mutual fund
industry now manages more than $2.3 trillion for investors. More than half of
that money has come into mutual funds in just the last four years. Today, there
are more than 95 million mutual fund shareholder accounts. That's up from 12
million in 1980. These are people, like you, who are investing in mutual funds
to save for a home, to send their children to college or to build a nest egg for
a comfortable retirement. This explosive growth, coupled with the growing
complexity of the financial landscape, has made all of us in the mutual fund
industry work harder to inform our shareholders.

   At John Hancock Funds, we strive to educate you about all aspects of your
fund: the performance, the strategies and the holdings. We want you to fully
understand what you own. We want you to have realistic expectations of the
potential rewards as well as the potential risks of your investment. These
shareholder reports -- which we send you twice a year -- are the best way to
give you the most in-depth and up-to-date information.

   In the message that follows, the portfolio manager gives a candid commentary
on the market environment; the factors that affected performance; the fund's
current investment strategies; and the outlook for the months ahead. The ensuing
financial statements provide a comprehensive look at the fund's statistics and
holdings. We've included explanations of what each financial statement shows and
how it is used.

   We hope you find these shareholder reports a useful tool in evaluating your
investments. Of course, if you have any questions or need more information, feel
free to call one of our customer service representatives on our toll-free line
at 1-800-225-5291, from 8:00 a.m. to 8:00 p.m. eastern time, Monday through
Friday.

Sincerely,

/s/ Edward J. Boudreau, Jr.

Dianne Sales-Singer is a member of the portfolio management team of John Hancock
California Tax-Free Income Fund. Ms. Sales-Singer, who joined John Hancock in
1989, also manages John Hancock Tax-Exempt Series Fund: California Portfolio and
Massachusetts Portfolio. Prior to becoming a portfolio manager, she was a senior
research officer following all sectors of the municipal bond market.

Falling interest rates and positive supply/ demand fundamentals drove municipal
bond prices higher during the first six months of 1995. By late last year, the
municipal bond market had reached a bottom after suffering from rising interest
rates and relatively weak demand through most of 1994. However, beginning in
January, municipals made a rapid recovery, buoyed by the prospect of lower
interest rates, rising demand and limited supply of new municipal bonds.

   While municipals outperformed Treasury securities in the first quarter, a
flurry of press coverage about various flat tax proposals in the second quarter
gave the market an excuse to consolidate. In late June, Orange County regained
the market's attention as voters failed to approve a sales tax increase that
would have assisted the County in dealing with its substantial investment
losses. While municipals

gave up some ground versus Treasuries, the overall environment continued to be
positive for bonds, as evidence of a slowing economy and muted inflation pushed
fixed-income markets higher.

A LOOK AT PERFORMANCE

For the six months ended June 30, 1995, John Hancock California Tax-Free Income
Fund's Class A and Class B shares posted returns of 11.81% and 11.40%,
respectively, at net asset value. Those returns outpaced the average tax-exempt
California fund's return of 9.70% for the same period, according to Lipper
Analytical Services.(1)

   The Fund's historic emphasis on long-term results returned large benefits to
shareholders in the first half of 1995. In 1994, a long average duration made
the Fund more vulnerable to rising interest rates. However, as rates fell in
1995, our heightened interest-rate sensitivity -- or duration -- allowed our
holdings to appreciate more rapidly than funds with shorter durations. Duration
is a measure of the interest-rate sensitivity of a portfolio, taking into
account maturity, coupon structure and call risk. The longer a fund's duration,
the more its share price will rise when interest rates fall, or fall when
interest rates rise. The Fund's longer-than-average duration at the close of
1994 was the primary reason for its outperformance in the first half of this
year.

STRATEGY CHANGES

Recently, however, we've used the market's strength to shorten the Fund's
duration. The tremendous rally in the first quarter caused the municipal yield
curve (or the difference between short- and long-term yields) to flatten.
Generally, when the yield curve is flat, investors aren't rewarded with much
additional yield for buying longer-term bonds. As a result, we shifted some of
our holdings out of longer-term bonds and into shorter-term bonds. That move
trimmed the Fund's duration slightly. We also continued to improve the Fund's
call protection, which simply means we focused on bonds that the issuer can't
redeem before their terms expire. That helps to protect the Fund's income
stream.

   The market's rally also provided us with a great opportunity to improve the
Fund's credit quality. Credit spreads (or the difference in yields between low-
and high-quality bonds) compressed. That meant lower-quality bonds didn't offer
much additional yield over higher-quality bonds. As a result, we sold some
lower-rated bonds and replaced them with higher-quality holdings. By making this
exchange when we did, we were able to upgrade the Fund's credit quality without
sacrificing much income.

ORANGE COUNTY

pool. However, these bonds have a specific source of repayment separate and
distinct from the County's funds. The market has recognized the value of these
bonds, making them some of our best performers so far this year.

OUTLOOK AND STRATEGY

There's evidence that the national economy is growing at a moderate pace. But in
our view, the slowdown isn't enough to throw the nation back into a recession.
With slow, but steady growth, we believe interest rates will be more stable and
municipal bonds could remain in a fairly narrow trading range for the balance of
the year. If that's the case, it's important for shareholders to realize that
the municipal bond market's performance will most likely be less dependent on
bond prices rising than it was in the first half of the year. So to add value,
we'll continue to apply careful credit research to identify bonds that offer the
potential for appreciation based on improving credit fundamentals. We'll also
continue to look for situations that will provide the Fund with an attractive
level of income.

   California's economy seems to have bottomed, and some areas of the state have
shown signs of improvement. That has helped state revenues come more in line
with expenses, which is a positive. Many California counties, on the other hand,
will continue to be challenged by rising costs, so more restructuring may be
needed on this level.

   Going forward, worry about the future of tax reform and its effect on
municipal bonds could cause some volatility in the market, as it did briefly in
April when the idea was first introduced. However, we don't believe that any
major tax reform will be enacted before 1997. In our view, there are several
reasons to be optimistic about the municipal market. By the end of June,
municipal bonds looked relatively cheap compared to U.S. Treasury securities.
When that last occurred -- at the end of 1994 -- municipal bonds rallied. Also,
demand for municipals is relatively stable and supply is limited. That should
bode well for municipal bond prices for the rest of the year.

                             A LOOK AT PERFORMANCE


The tables on the right show the cumulative total returns and the average annual
total returns for John Hancock California Tax-Free Income Fund. Total return is
a performance measure that equals the sum of all income and capital gains
dividends, assuming reinvestment of these distributions, and the change in the
price of the fund's shares, expressed as a percentage of the fund's share.
Performance figures include the maximum applicable sales charge of 4.5% for
Class A shares. The effect of the maximum contingent deferred sales charge for
Class B shares (maximum 5% and declining to 0% over six years) is included in
Class B performance. Remember that all figures represent past performance and
are no guarantee of how the Fund will perform in the future. Also, keep in mind
that the total return and share price of the Fund's investments will fluctuate.
As a result, your Fund's shares may be worth more or less than their original
cost depending on when you sell them.

The charts on the right show how much a $10,000 investment in John Hancock
California Tax-Free Income Fund would be worth on June 30, 1995, assuming you
invested on the day each class of shares started and reinvested all
distributions. For comparison, we've shown the same $10,000 investment in the
Lehman Bros. Municipal Bond Index--an unmanaged index that includes
approximately 15,000 bonds and is commonly used as a measure of bond
performance.

              John Hancock Funds - California Tax-Free Income Fund

(UNAUDITED)
NOTE A --
ACCOUNTING POLICIES

John Hancock California Tax-Free Income Fund (the "Fund") is a diversified
open-end investment management company registered under the Investment Company
Act of 1940.

    The Trustees have authorized the issuance of two classes of the Fund,
designated as Class A and Class B. The shares of each class represent an
interest in the same portfolio of investments of the Fund and have equal rights
to voting, redemption, dividends and liquidation, except that certain expenses,
subject to the approval of the Trustees, may be applied differently to each
class of shares in accordance with current regulations of the Securities and
Exchange Commission and the Internal Revenue Service. Shareholders of a class
which bears distribution/service expenses under the terms of a distribution
plan, have exclusive voting rights regarding such distribution plan. Class A
shares are subject to an initial sales charge of up to 4.50% and a 12b-1
distribution plan. Prior to May 15, 1995, the maximum sales charge was 4.75%.
Class B shares are subject to a contingent deferred sales charge and a separate
12b-1 distribution plan. Significant accounting policies of the Fund are as
follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or, at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost which approximates market value.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly-owned subsidiary of The Berkeley Financial Group,
may participate in a joint repurchase agreement. Aggregate cash balances are
invested in one or more repurchase agreements, whose underlying securities are
obligations of the U.S. government and/or its agencies. The Fund's custodian
bank receives delivery of the underlying securities for the joint account on the
Fund's behalf. The Adviser is responsible for ensuring that the agreement is
fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis.

FEDERAL INCOME TAXES The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gain on
investments, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has approximately $268,000
of capital loss carryforward available, to the extent provided by regulations,
to offset future net realized capital gains. If such carryforwards are used by
the Fund, no capital gain distribution will be made. The carryforward expires
December 31, 2002.

DIVIDENDS, DISTRIBUTIONS, AND INTEREST Interest income on investment securities
is recorded on the accrual basis.

    The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund with
respect to each class of shares will be calculated in the same manner, at the
same time and will be in the same amount, except for the effect of expenses that
may be applied differently to each class as explained previously.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are determined at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution/service fees, if any, are calculated daily at the class level based
on the appropriate net assets of each class and the specific expense rate(s)
applicable of each class.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts for speculative purposes and/or to hedge against the effects of
fluctuations in interest rates and other market conditions. At the time the Fund
enters into a financial futures contract, it is


                                       19

                         NOTES TO FINANCIAL STATEMENTS

              John Hancock Funds - California Tax-Free Income Fund


required to deposit with its custodian a specified amount of cash or U.S.
government securities, known as "initial margin", equal to a certain percentage
of the value of the financial futures contract being traded. Each day, the
futures contract is valued at the official settlement price of the board of
trade or U.S. commodities exchange. Subsequent payments, known as "variation
margin", to and from the broker are made on a daily basis as the market price of
the financial futures contract fluctuates. Daily variation margin adjustments,
arising from this "mark to market", are recorded by the Fund as unrealized gains
or losses.

    When the contracts are closed, the Fund recognizes a gain or loss. Risks of
entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contract may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuations imposed by an exchange.

    For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures transactions.

    At June 30, 1995, open positions in financial futures contracts were as
follows:

</TABLE>


    At June 30, 1995, the Fund has deposited in a segregated account $215,000 to
cover margin requirements on open financial futures contracts.

PREMIUM AND DISCOUNT For tax-exempt issues, the Fund amortizes the amount paid
in excess of par value on securities purchased from either the date of purchase
or date of issue to date of sale, maturity or to next call date, if applicable.
The Fund accretes original issue discount from par value on securities purchased
from either the date of issue or the date of purchase over the life of the
security, as required by the Internal Revenue Code. The Fund records market
discount on bonds purchased after April 30, 1993 at the time of disposition.

NOTE B --
MANAGEMENT FEE AND TRANSACTIONS WITH
AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program at an annual
rate of 0.55% of the Fund's average daily net asset value.

    In the event normal operating expenses of the Fund, exclusive of certain
expenses prescribed by state law, are in excess of the most restrictive state
limit where the Fund is registered to sell shares, the fee payable to the
Adviser will be reduced to the extent of such excess, and the Adviser will make
additional arrangements necessary to eliminate any remaining excess expenses.
The current limits are 2.5% of the first $30,000,000 of the Fund's average daily
net asset value, 2.0% of the next $70,000,000, and 1.5% of the remaining average
daily net asset value.

    The Adviser has temporarily agreed to continue to limit the Fund's operating
expenses to 0.75% and 1.50% of the average net assets attributable to Class A
and Class B, respectively. Accordingly, for the period ended June 30, 1995, the
reduction in the Fund's expenses collectively with any additional amounts not
borne by the Fund by virtue of the expense limit amounted to $223,994.

    The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly-owned subsidiary of the Adviser. For the period ended June 30,
1995, JH Funds received net sales charges on sales of Class A shares of the Fund
in the amount of $265,595. Out of this amount, $31,330 was retained and used for
printing prospectuses, advertising, sales literature and other purposes,
$231,015 was paid as sales commissions and service fees to unrelated
broker-dealers and $3,250 was paid as sales commissions and service fees to
sales personnel of John Hancock Distributors, Inc.

              John Hancock Funds - California Tax-Free Income Fund

("Distributors"), Tucker Anthony, Incorporated ("Tucker Anthony") and Sutro &
Co., Inc. ("Sutro"). Distributors is a wholly-owned subsidiary of John Hancock
Funds. The Adviser's indirect parent, John Hancock Mutual Life Insurance
Company, is the indirect sole shareholder of Distributors and John Hancock
Freedom Securities Corporation and its subsidiaries, which include Tucker
Anthony and Sutro, all of which are broker-dealers.

    Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.0% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from CDSC are paid to JH Funds and are used in whole or in part to defray its
expenses related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended June 30, 1995,
contingent deferred sales charges received by Broker Services amounted to
$348,507.

    In addition, to compensate JH Funds for the services it provides as
distributors of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A and Class B shares pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses at an annual rate not to exceed
0.15% of Class A average daily net assets and 1.00% of Class B average daily net
assets to reimburse JH Funds for its distribution and service costs. John
Hancock Funds has temporarily agreed to limit the distribution and service fees
pursuant to the Class B plan to 0.90% of the average daily net assets. Up to a
maximum of 0.15% for Class A and 0.25% for Class B of these payments may be
service fees as defined by the amended Rules of Fair Practice of the National
Association of Securities Dealers. Under the amended Rules of Fair Practice,
curtailment of a portion of the Fund's 12b-1 payments could occur under certain
circumstances.

    The Board of Trustees approved a shareholder servicing agreement between the
Fund and John Hancock Investor Services Corporation ("Investor Services"), a
wholly owned subsidiary of The Berkeley Financial Group, for the period between
December 22, 1994 and May 12, 1995, inclusive under which Investor Services
processed telephone transactions on behalf of the Fund. As of May 15, 1995, the
Fund entered into a full service transfer agent agreement with Investor
Services. Prior to this date The Shareholder Services Group was the transfer
agent. The Fund will pay Investor Services a fee based on the number of
shareholder accounts and certain out-of-pocket expenses.

    Mr. Edward J. Boudreau is a director and officer of the Adviser and its
affiliates as well as a Trustees of the Fund. The compensation of unaffiliated
Trustees is borne by the Fund. Effective with the fees paid for 1995, the
unaffiliated Trustees may elect to defer for tax purposes their receipt of this
compensation under the John Hancock Group of Funds Deferred Compensation Plan.
The Fund will make investments into other John Hancock funds, as applicable, to
cover its liability with regard to the deferred compensation. Investments to
cover the Fund's deferred compensation liability will be recorded on the Fund's
books as an other asset. The deferred compensation liability will be marked to
market on a periodic basis and income earned by the investment will be recorded
on the Fund's books.

    The Fund has an independent advisory board composed of certain members of
the former Transamerica Board of Trustees who provide advice to the current
Trustees in order to facilitate a smooth management transition for which the
Fund pays the advisory board and its counsel a fee.
