================================CHAIRMAN'S MESSAGE==============================

DEAR FELLOW SHAREHOLDERS:

         Nineteen ninety-eight was a year that gave even veteran financial
market investors pause - and not a little heartburn. The stock market produced a
record fourth straight year of double-digit returns, but volatility was
breathtaking along the way. With the exception of the U.S. Treasury market, even
bonds - considered a safer alternative to stocks - went on a roller coaster
ride.

         But there was one clear lesson from 1998: that sticking out the tough
times paid off. After reaching new highs last July, stocks plunged in August in
one of their worst sell-offs in years. The average U.S. diversified-equity
mutual fund fell 16.8% in the month of August alone. For many mutual fund
investors, it was the largest one-month loss they had ever experienced, since
the average equity fund had only had three such double-digit monthly losses in
the previous 20 years, most recently in October 1987. But, in a dramatic
reversal of fortune, the market staged a stunning rebound in the fourth quarter.
The average U.S. diversified-equity fund made up all its August lost ground and
then some, returning 18.8% between October and December. The final result for
the year: an average 14.52% return, as calculated by Lipper, Inc.

- --------------------------------------------------------------------------------

Officer, flush right next to second paragraph.]
- --------------------------------------------------------------------------------

         Given the dramatic swings, investors who tried to time the market's ups
and downs encountered a sharp whipsaw. We are very encouraged to report that an
overwhelming majority of mutual fund investors sat tight during last summer's
discontent; some even used the market's drop to pick up bargains. It was a clear
sign that long-term investors are willing to accept the reality of shorter-term
volatility.

         In the first two months of 1999, the financial markets showed more
stability and the Dow Jones Industrial Average approached record highs. While
volatility remains on many investors' minds, at this time of year thoughts also
turn to more taxing matters. In our view, now is a perfect time to focus on how
much of your hard-earned money you are able to keep. Part of a good tax-planning
strategy should involve a review of your portfolio to ensure that you are taking
advantage of all available ways to minimize and defer your tax payments - in an
effort to maximize investment returns.

         We encourage you to work with your investment professional to consider
the various options. These include focusing on tax-exempt funds, contributing
the maximum to retirement plans, establishing or adding to IRAs and funding a
variable annuity. After all, while it's every American's responsibility to pay
taxes, there's no reason to pay more than your fair share.

Sincerely,

/s/Edward J. Boudreau, Jr.

                     Supply pressures hold municipals back,
                      then ease at end of six-month period

Supply and demand were once again the primary factors affecting municipal bond
performance during the past six months.  From September through year end, a glut
of municipal bonds flooded the market - a trend that characterized much of 1998.
In fact,  the  supply of new  municipal  bonds  increased  more than 40% in 1998
versus 1997,  making it the second  strongest year of municipal bond issuance on
record. This heavy influx of new bonds, due to continued low interest rates, put
downward   pressure  on  prices.   The  net  result  was  that  municipal  bonds
underperformed  U.S.  Treasuries  for  most  of  1998  and  reached  their  most
attractive  price levels versus  Treasuries in almost five years. The one bright
spot was that many  non-traditional  buyers  crossed  over  into the  tax-exempt
market to take advantage of these incredible values. These so-called "crossover"
buyers  provided an  important  source of demand for the flood of new  issuance.

         With the start of 1999, however, the tables turned and municipal bonds
began to outperform U.S. Treasuries. First, emerging-market concerns faded,
taking the "flight to quality" premium out of Treasuries. At the same time,
worries about stronger-than-expected U.S. economic growth pushed interest rates
up and bond prices down. In contrast, municipal bonds were already at such low
price levels that they had much less downside risk than Treasuries.

1999."]
- --------------------------------------------------------------------------------

Finally, municipal-bond issuance declined dramatically in January and February,
eliminating the supply pressures experienced in 1998. As a result, municipal
investors saw their holdings handily outperform in early 1999.

Performance scorecard 

For the six months ended February 28, 1999, John Hancock California Tax-Free
Income Fund's Class A and Class B shares returned 2.21% and 1.84%, respectively,
at net asset value. By comparison, the average California municipal bond fund
returned 2.09%, according to Lipper, Inc.1 Keep in mind that your net asset
value return will be different from the Fund's performance if you were not
invested in the Fund for the entire period and did not reinvest all
distributions. Please see pages six and seven for longer-term performance
information.

- --------------------------------------------------------------------------------

         The Fund's performance benefited from excellent credit selection as
strong economic growth generated stronger-than-expected revenues, often
resulting in credit upgrades. Performance in the first four months of the period
also benefited from a somewhat longer duration posture, which provided gains as
interest rates fell. Duration measures a fund's sensitivity to interest-rate
changes. The longer the duration, the more sensitive the fund's share price.

         Throughout the period, we kept the Fund's duration relatively long in
order to take advantage of falling interest rates. However, when rates increased
suddenly in the first two months of 1999, our relatively long duration was a
slight disadvantage.

Focus on call protection, credit analysis 

As we've discussed in past reports, we've maintained a strong emphasis on call
protection, which guards a bond from being redeemed by its issuer for a certain
period of time. Strong call protection is especially important in periods of
falling interest rates, when issuers often try to refinance their bonds at lower
interest rates. If a bond gets "called away" or redeemed early, investors are
forced to reinvest their money in bonds with lower yields. By focusing on issues
with strong call protection, we have been able to maintain the Fund's
competitive yield in a falling interest-rate environment.

         Applying our in-depth credit analysis, we continued to search for
lower-quality bonds with both attractive yields and improving credit profiles.
This strategy served us well, as the gap between yields on higher- and
lower-quality bonds continued to narrow. Against this backdrop, several of our
lower-quality holdings were big winners. A perfect example was our bonds issued
by the San Joaquin Hills Transportation Corridor Agency. This toll-road project
took the opportunity to refinance debt, thereby reducing the amount of its
interest payments. The Fund benefited as our holdings received a credit upgrade
from a rating of BBB to AAA, the highest rating possible. Since our San Joaquin
holdings were primarily non-callable, the upgrade occurred without suffering the
risk of a bond call.

- --------------------------------------------------------------------------------

Outlook  

Looking ahead, we expect that California's economy will continue to be strong.
The state has weathered the Asian financial crisis well, especially given that
approximately one third of U.S. exports to Asia come from California. With a new
governor in office, we are keeping a close eye on the budget to make sure that
the state's strong fiscal situation remains intact. The proposed budget assumes
continued strong economic growth and a spend-down of reserves.

         The macroenvironment remains favorable for municipal bonds. Most
important, we anticipate that new municipal bond issuance will decline roughly
20% in 1999 as refunding opportunities become more scarce. We've already seen
this trend start to take hold in the first two months of this year. Lighter
supply should help firm demand from traditional buyers. What's more, municipal
bonds still offer very attractive values relative to U.S. Treasuries, meaning
they still have plenty of upside potential.

         Despite stronger-than-expected growth in the first few months of this
year, there are still no concrete signs of inflation on the horizon. And with
most world economies still sluggish, we believe that pricing power will remain
limited and, therefore, inflation will stay in check for the foreseeable future.
A continued low-inflation environment should provide a positive backdrop for
municipal bonds.

         While the bulk of the interest-rate declines are probably over, we
don't expect rates to increase significantly in the months ahead, given the
positive inflation outlook. However, should economic performance continue to
exceed expectations, we will look to trim our duration to a more neutral
position. In addition, we will keep a close eye on credit developments in
sectors such as electric utilities and health care where we have been
selectively weeding out weaker names. Overall, our focus will remain on our
tried-and-true investment strategy - looking for value and attractive yield
opportunities, thinning exposure to sectors that are vulnerable to widening
credit spreads and finally, continuing to maintain strong call protection.

                             A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock California Tax-Free Income Fund. Total return
measures the change in value of an investment from the beginning to the end of a
period,  assuming all distributions were reinvested. 

For Class A shares, total return figures include a maximum applicable sales
charge of 4.50%. Class B performance reflects a maximum contingent deferred
sales charge (maximum 5% and declining to 0% over six years).

All figures represent past performance and are no guarantee of future results.
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. Please read your
prospectus carefully before you invest or send money.


Please  note that a portion  of the Fund's  income may be subject to taxes,  and
some investors may be subject to the  Alternative  Minimum Tax (AMT).  Also note
that capital gains are taxable.

              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  management   investment  company  registered  under  the
Investment  Company  Act of 1940.  The  investment  objective  of the Fund is to
provide as high a level of current  income exempt from both federal income taxes
and  California  personal  income taxes as is consistent  with  preservation  of
capital.

         The Trustees have authorized the issuance of multiple classes of shares
of the Fund, designated as Class A, Class B and Class C shares. The Fund issued
Class C shares for the first time on April 1, 1999. The shares of each class
represent an interest in the same portfolio of investments of the Fund and have
equal rights to voting, redemptions, 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 and service expenses under
terms of a distribution plan, have exclusive voting rights to that 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,
Inc., 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 $8,548,263 of capital
loss carryforwards available, to the extent provided by regulations, to offset
future net realized capital gains. If such carryforwards are used by the Fund,
no capital gains distribution will be made. The carryforwards expire as follows:
August 31, 2001 - $35,453, August 31, 2002 - $277,226, August 31, 2003 -
$5,169,717, August 31, 2004 - $2,378,578, August 31, 2005 - $7,774 and August
31, 2006 - $679,515.

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.

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 time of disposition.

==========================NOTES TO FINANCIAL STATEMENTS=========================

              John Hancock Funds - California Tax-Free Income Fund

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are calculated at the Fund level and allocated daily to each class of
shares based on the relative net assets of the respective classes. Distribution
and 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
to each class.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. Effective March 12, 1999,
the Fund entered into a syndicated line of credit agreement with various banks,
and the agreements previously in effect were terminated. This agreement enables
the Fund to participate with other funds managed by the Adviser in unsecured
lines of credit with banks which permit borrowings up to $500 million,
collectively. Interest is charged to each fund based on its borrowing. In
addition, a commitment fee is charged based on the average daily unused portion
of the line of credit and is allocated among the participating funds. The Fund
had no borrowing activity for the period ended February 28, 1999.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts to hedge against the effects of fluctuations in interest rates and
other market conditions. Buying futures tends to increase the Fund's exposure to
the underlying instrument. Selling futures tends to decrease the Fund's exposure
to the underlying instrument or hedge other Fund instruments. At the time the
Fund enters into a financial futures contract, it will be 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 on the board of trade or U.S.
commodities exchange on which it trades. 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," will be 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 contracts 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
fluctuation 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 contracts.

                  At February 28, 1999, open positions in financial futures
contracts were as follows:



                                                                     UNREALIZED

JUN 99          85 U.S. Treasury Notes       LONG                     $173,251
                                                                      ========
                           
         At February 28, 1999, the Fund has deposited $500,000 par value of City
of Davis Redevelopment Agency, 7.00%, 09-01-24, in a segregated account to cover
margin requirements on open financial futures contracts.

OPTIONS The Fund may purchase options contracts. Listed options will be valued
at the last quoted sales price on the exchange on which they are primarily
traded. Over-the-counter options are valued at the mean between the last bid and
asked prices. Upon the writing of a call or put option, an amount equal to the
premium received by the Fund will be included in the Statement of Assets and
Liabilities as an asset and corresponding liability. The amount of the liability
will be subsequently marked to market to reflect the current market value of the
written option.

         The Fund may use options contracts to manage its exposure to changing
security prices. Writing puts and buying calls will tend to increase the Fund's
exposure to the underlying instrument and buying puts and writing calls will
tend to decrease the Fund's exposure to the underlying instrument, or hedge
other Fund investments.

==========================NOTES TO FINANCIAL STATEMENTS=========================

              John Hancock Funds - California Tax-Free Income Fund


         The maximum exposure to loss for any purchased options will be limited
to the premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value will reflect the maximum exposure
of the Fund in these contracts, but the actual exposure will be limited to the
change in value of the contract over the period the contract remains open.

         Risks may also arise if counterparties do not perform under the
contract's terms ("credit risk"), or if the Fund is unable to offset a contract
with a counterparty on a timely basis ("liquidity risk"). Exchange-traded
options have minimal credit risk as the exchanges act as counterparties to each
transaction and only present liquidity risk in highly unusual market conditions.
To minimize credit and liquidity risks in over-the-counter option contracts, the
Fund will continuously monitor the creditworthiness of all its counterparties.

         At any particular time, except for purchased options, market or credit
risk may involve amounts in excess of those reflected in the Fund's Statement of
Assets and Liabilities.

         There were no written option transactions for the period ended February
28, 1999.


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 equivalent on
an annual basis to 0.55% of the Fund's average daily net asset value.

         The Adviser has voluntarily agreed 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, the reduction in the Adviser's fee
amounted to $113,548 for the period ended February 28, 1999. This limitation may
not be discontinued until at least January 1, 2000.

         The Fund has an agreement with its custodian bank under which $32,300
of custodian fees have been reduced by balance credits applied during the period
ended February 28, 1999. If the Fund had not entered into this agreement, the
assets not invested, on which these balance credits were earned, could have
produced taxable income.

         The Fund has a distribution agreement with John Hancock Funds, Inc.
("JH Funds"), a wholly owned subsidiary of the Adviser. For the period ended
February 28, 1999, net sales charges received with regard to sales of Class A
shares amounted to $350,453. Out of this amount, $26,201 was retained and used
for printing prospectuses, advertising, sales literature and other purposes,
$291,113 was paid as sales commissions to unrelated broker-dealers and $33,139
was paid as sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer, formerly known as John Hancock
Distributors, Inc. The Adviser's indirect parent, John Hancock Mutual Life
Insurance Company ("JHMLICo"), is the indirect sole shareholder of Signator
Investors.

         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 the 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 February 28,
1999, contingent deferred sales charges paid to JH Funds amounted to $86,706.

         In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A and Class B pursuant to Rule 12b-1 under the Investment
Company Act of 1940. Accordingly, the Fund will make payments to JH Funds 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. JH Funds has temporarily agreed to limit the distribution and
service fees pursuant to the Class B plans to 0.90% of the average daily net
assets. Up to a maximum of 0.25% of such 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 Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHMLICo. The
Fund pays transfer agent fees based on the number of shareholder accounts and
certain out-of-pocket expenses.

         The Fund has an agreement with the Adviser to perform necessary tax and
financial management services for the Fund. The compensation for the period was
at an annual rate of less than 0.02% of the average net assets of the Fund.

         Mr. Edward J. Boudreau, Jr., Mr. Stephen L. Brown, Ms. Anne C. Hodsdon

unaffiliated Trustees is borne by the Fund. 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 makes investments
into other John Hancock funds, as applicable, to cover its liability for the
deferred compensation. Investments to cover the Fund's deferred compensation
liability are recorded on the Fund's books as an other asset. The deferred
compensation liability and the related other asset are always equal and are
marked to market on a periodic basis to reflect any income earned by the
investment as well as any unrealized gains or losses. At February 28, 1999 the
Fund's investments to cover the deferred compensation liability had unrealized
appreciation of $3,578.
