                               Chairman's Message

DEAR FELLOW SHAREHOLDERS:

The Taxpayer  Relief Act of 1997 recently  signed into law by President  Clinton
includes new twists and important changes to Individual Retirement Account (IRA)
laws. The provisions will, among other things,  allow more people to qualify for
annual  tax-deductible IRA contributions and to save tax-free for college.  They
also allow IRA investors to withdraw money  penalty-free  from all IRAs to buy a
first home or pay for college expenses.

   For existing  deductible  IRAs,  the law doubles  income limits over the next
eight to 10 years for those eligible to deduct an annual IRA  contribution of up
to $2,000.  For individuals,  the annual income cap will increase  incrementally
from the  current  $25,000 to  $50,000 by 2005.  For  couples,  the limit  would
increase from $40,000 today to $80,000 in 2007.  The new law allows  non-working
spouses to make IRA  contributions  even if their spouse is covered by a pension
plan at work, provided the couple's joint income is less than $150,000.

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

   The law also creates two new IRA investment  vehicles.  One, called the "Roth
IRA" after its principal congressional sponsor, allows for non-deductible annual
contributions up to a $2,000 maximum. But income accumulates tax-free and if the
account has been open for five  years,  distributions  are  tax-free if they are
used after age 591/2 or upon death,  disability or a first-time  home  purchase.
Withdrawals for higher-education expenses would not be subject to a 10% penalty.
Eligible investors must earn less than $95,000 per year individually or $150,000
per couple.

   A second  new IRA plan is  called  the  "Education  IRA"  which  allows  non-
deductible  contributions  of up to $500  per  year,  per  child  under  age 18.
Earnings in the account accumulate tax-free,  and withdrawals are also not taxed
when applied toward undergraduate or graduate-level expenses. Eligible investors
are subject to the same income restrictions as the Roth IRA.

   The law has also made some  important  changes in capital gains tax rates and
estate tax laws. But the devil is in the details,  and so we recommend exploring
how you can benefit from the changes with your investment  professional  and tax
advisor.  The Taxpayer  Relief Act of 1997 gives  investors  new options  toward
savings. It's a move we applaud.

Sincerely,

/s/ Edward J. Boudreau, Jr.

                High-yield municipals turn in strong performance
                ------------------------------------------------

Troubled by  contradictory  news on the job,  retail spending and consumer price
fronts,  bonds see-sawed during much of the first half of the Fund's fiscal year
beginning  September 1, 1996.  While many cheer strong  economic  reports,  bond
investors  fear them because they may be an indication  that inflation is on the
rise.  Inflation,  of course,  is the bugaboo of bond investing  because it eats
away at the value of bonds' fixed-income payments. In March, the Federal Reserve
Board raised  short-term  interest rates one-quarter of a percentage point, in a
"pre-emptive" effort to stave off any future inflation. That action rattled bond
investors who pushed bond prices lower and bond yields higher in the spring.

   It really  wasn't  until April when bond prices  showed  definitive  signs of
sustained  improvement.  At that point,  there was plenty for bond  investors to
cheer about.  Even though the U.S.  unemployment  rate hit a 23-year low,  there
were  no  real  signs  that   wages--often   a  major   contributor   to  higher
inflation--were  rising.  Adding further fuel to the bond market's  optimism was
Federal Reserve Board Chairman Alan Greenspan's  July testimony to Congress.  He
admitted   puzzlement   that  despite  the  economy's   strong  growth  and  low
unemployment,  no inflationary pressures were brewing, and he strongly hinted no
further interest-rate hikes were on the immediate horizon.

"High-yield municipals ...did particularly well in this environment."

   High-yield  municipals,  which the Fund emphasizes,  did particularly well in
this environment.  The strong demand for, and low supply of, high-yielding bonds
helped them out-

perform their higher-quality, lower-yielding counterparts. The supply of insured
bonds rose during the past year, which resulted in a dramatic drop in the supply
of  uninsured,  high-yielding  bonds.  Investors  seeking  high levels of income
gravitated  toward the  lower-rated,  high-yielding  bonds which helped  sustain
strong demand.  Lower-rated  bonds carry higher yields as  compensation  for the
risk that their issuers may be more likely than higher-rated  issuers to default
on their debt. An insurer,  on the other hand,  guarantees the timely payment of
principal and interest regardless of the quality of the underlying bond.

A look at performance
For the year ended August 31, 1997,  John  Hancock  High Yield  Tax-Free  Fund's
Class  A  and  Class  B  shares   posted  total  returns  of  8.29%  and  7.51%,
respectively,  at net asset value.  Those returns lagged the average  high-yield
municipal  bond fund's return of 9.68% for the same period,  according to Lipper
Analytical  Services,  Inc.  1 Please  see pages  six and seven for  longer-term
performance  information.  The Fund's lag can be attributed to the disappointing
performance of several paper  recycling  plants.  Because the price of paper was
weak during the past year, the entire sector suffered.

left  column  is  "Investments";  the  header  for the right  column is  "Recent
performance  ...  and  what's  behind the  numbers.  The first  listing is Paper
recycling  projects  followed  by a down  arrow and the  phrase  "Falling  paper

phrase "Improving fiscal and economic situation".  The third listing is Arapahoe
County followed by an up arrow and the phrase "Bonds were advance  refunded".  A
footnote below states "See 'Schedule of  Investments.'  Investment  holdings are
subject to change".]

Among our best performers were general obligation bonds (GOs) issued by New York
City and the District of Columbia.  GOs are  municipal  bonds backed by the full
faith and credit (which  includes the taxing power) of a  municipality,  and are
repaid with general  revenue,  including  taxes. As the economy  improved in New
York City,  tax revenues also improved,  causing the bonds to rally.  As for the
District of  Columbia,  President  Clinton's  proposal to revamp the  district's
financial  structure  caused an improvement in the credit standing of its bonds.
Another  performance boost came when our holdings in Bedford Park,  Illinois and
Arapahoe  County  Capital  Improvement  were  advance  refunded.   With  advance
refunding, the bonds became backed by high-quality U.S. Treasury securities, and
after the refunding, they generally rose in value.

Strategy overview
Throughout  the past year, we continued to look for  opportunities  to diversify
our holdings across a greater number of high-yielding  bonds.  Admittedly,  this
wasn't always easy because the supply of high-yielding bonds has been relatively
low. Furthermore,  the strong demand for many high-yield bonds has pushed prices
beyond what we

scaled in increments of 2%, with 10% at the top and 0% at the bottom. Within the

the 7.51% total return for the John Hancock High Yield Tax-Free  Fund:  Class B.

believe  are  reasonable  from a  risk/reward  standpoint.  With the help of our
research analysts,  we focused on finding lower-rated bonds that we believe have
underlying  financial strength and whose reward, or income, we believe justifies
the  added  credit  risk.  Two  recent  additions  that  fit our  criteria  were
pollution-control bonds backed by Laidlaw issued by Toole County, Utah and Grand
Haven Development District of Florida.

   We also continued to emphasize bonds with attractive call protection.  A call
feature is part of an  agreement a bond issuer  makes with the buyer  describing
the  schedule  and price of  redemption  before  maturity.  During  periods when
interest rates are falling,  investors  generally don't want their bond holdings
to be called  away,  because  they  will be  forced to invest at lower  interest
rates. We focused on  non-callable  bonds (those that can't be redeemed by their
issuer before maturity) and bonds that have relatively long call dates.

Outlook
For now, the economic  backdrop  appears  favorable  for  municipal  bonds.  The
economy continues to look moderately  strong, yet all appears to be quiet on the
inflationary  front.  However,  we're not necessarily ruling out a further small
interest rate boost.  If the Federal  Reserve  Board sees  something it believes
could be inflationary -- such as a  stronger-than-expected  employment report --
it would be  likely to act  swiftly  to  curtail  inflation  before  it  becomes
problematic.  But in our view,  even a small,  quarter-percentage-point  hike in
interest rates probably would not rattle the bond markets to a great extent.  As
for  high-yield  municipal  bonds,  the  continued  low supply and strong demand
should help their performance going forward.

"For now, the economic backdrop appears favorable for municipal bonds."

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock High Yield Tax-Free  Fund.  Total return is a
performance  measure  that  equals  the  sum of all  income  and  capital  gains
distributions,  assuming reinvestment of these distributions,  and the change in
the price of the Fund's  shares,  expressed  as a  percentage  of the Fund's net
asset value per 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.  Performance  is affected by a 12b-1 plan.
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.  

   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. Also note that
capital gains are taxable.

The charts on the right show how much a $10,000  investment in John Hancock High
Yield  Tax-Free  Fund would be worth on August 31,  1997.  They  assume that you
invested on the day each class of shares started. They also assume that you have
reinvested  all  distributions.  For  comparison,  we've shown the same  $10,000
investment in the Lehman Brothers Municipal Bond Index--an  unmanaged index that
includes  approximately  15,000 bonds and is commonly  used as a measure of bond
performance.

                         NOTES TO FINANCIAL STATEMENTS

                 John Hancock Funds - High Yield Tax-Free Fund


NOTE A --
ACCOUNTING POLICIES
John  Hancock  Tax Free Bond  Trust (the  "Trust")  is a  diversified,  open-end
management  investment  company,  registered under the Investment Company Act of
1940.  The Trust  consists of two series:  John Hancock High Yield Tax-Free Fund
(the "Fund") and John Hancock  Tax-Free Bond Fund. The other series of the Trust
is reported in separate financial  statements.  The investment  objective of the
Fund is to provide as high a level of interest income exempt from federal income
taxes as is consistent with the  preservation of capital by investing  primarily
in municipal bonds,  notes and commercial paper, the interest on which is exempt
from federal income taxes. 

   The Board of Trustees  have  authorized  the issuance of multiple  classes of
shares of the Fund, designated as Class A and Class B shares. 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 Board of Trustees may be applied
differently  to each class of shares in accordance  with current  regulations of
the  Securities  and Exchange  Commission.  Shareholders  of a class which bears
distribution  and  service  expenses  under  terms of a  distribution  plan have
exclusive voting rights regarding 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 Board of 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
investment,  to its shareholders.  Therefore, no federal income tax provision is
required.  For federal income tax purposes, the Fund has $6,907,488 of a capital
loss carryforward  available,  to the extent provided by regulations,  to offset
future net realized  capital gains.  To the extent such  carryforward is used by
the Fund, no capital gains  distribution  will be made. The  carryforwards  will
expire as  follows:  August 31,  2002--$2,785,979,  August  31,  2003--$205,838,
August 31,  2004--$3,207,633 and August 31,  2005--$708,038.  Additionally,  net
capital  losses of $2,602,569  attributable  to security  transactions  incurred
after  October 31, 1996 are  treated as arising on the first day  (September  1,
1997) of the Fund's next taxable year.

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

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  appropriate  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.

EXPENSES The majority of the expenses of the Trust are directly  identifiable to
an individual  Fund.  Expenses which are not readily  identifiable to a specific
Fund  are  allocated  in  such  a  manner  as  deemed  equitable,   taking  into
consideration,  among  other  things,  the nature  and type of  expense  and the
relative sizes of the funds.

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.  These agreements  enable
the Fund to participate  with other Funds managed by the Adviser in an unsecured
line  of  credit  with a bank  which  permits  borrowings  up to  $400  million,
collectively.  Interest is charged to each Fund,  based on its  borrowing,  at a
rate equal to 0.50% over the Fed Funds Rate. In addition, a commitment fee, at a
rate of 0.075% per annum based on the average  daily unused  portion of the line
of credit, is allocated among the participating Funds. The Fund had no borrowing
activity for the year ended August 31, 1997.

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. 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 August 31,  1997 there were the  following  open  positions  in  financial
futures contracts:

                                                                  UNREALIZED
EXPIRATION          OPEN CONTRACTS                POSITION       DEPRECIATION
- ----------          --------------                --------       ------------
SEP 97              20 U.S. TREASURY BOND         SHORT            ($15,000)
                                                                    =======

   At August 31, 1997, the Fund has deposited $36,000 in a segregated account to
cover margin requirements on open financial futures contracts.

OPTIONS  Listed  options  will be valued at the last  quoted  sales price on the
exchange  on  which  they  are   primarily   traded.   Purchased   put  or  call
over-the-counter  options  will be valued  at the  average  of the "bid"  prices
obtained  from two  independent  brokers.  Written put or call  over-the-counter
options will be valued at the average of the "asked"  prices  obtained  from two
independent  brokers.  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 cor-

responding  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 option contracts to manage its exposure to the stock market.
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.

   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  period-end
Statement of Assets and Liabilities.

   There were no written option transactions for the year ended August 31, 1997.

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 the sum of (a) 0.625% of the first $75,000,000 of the Fund's
average daily net asset value, (b) 0.5625% of the next $75,000,000 and (c) 0.50%
of the Fund's average daily net asset value in excess of $150,000,000.

   The Fund has a  distribution  agreement  with John Hancock  Funds,  Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the year ended August 31,
1997, net sales charges received with regard to sales of Class A shares amounted
to  $215,849.  Out of this  amount,  $26,764 was  retained and used for printing
prospectuses,  advertising,  sales  literature and other purposes,  $174,321 was
paid as sales  commissions to unrelated  broker-dealers  and $14,764 was paid as
sales  commissions  to  sales  personnel  of  John  Hancock  Distributors,  Inc.
("Distributors"),  a related broker-dealer.  The Adviser's indirect parent, John
Hancock  Mutual  Life  Insurance  Company  ("JHMLICo"),  is  the  indirect  sole
shareholder of Distributors.

   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 year ended August 31, 1997,
contingent deferred sales charges paid to JH Funds amounted to $458,112.

   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 for
distribution  and service  expenses,  at an annual  rate not to exceed  0.30% 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.  The Fund has
temporarily  agreed to limit the distribution and service fees pursuant to Class
A to 0.25% 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.

                 John Hancock Funds - High Yield Tax-Free Fund


   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 Funds. The compensation for the year was
at an an annual rate of less than 0.02% of the average net assets of each Fund.

   Mr. Edward J.  Boudreau  Jr., Ms. Anne C. Hodsdon and Mr.  Richard S. Scipone
are directors  and/or officers of the Adviser and/or its affiliates,  as well as
Trustees of the Fund. The compensation of 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 another  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 August  31,  1997,  the  Fund's  investments  to cover the  deferred
compensation liability had unrealized appreciation of $1,714.

NOTE C --  
INVESTMENT TRANSACTIONS  
Purchases and proceeds from sales of securities,  other than  obligations of the
U.S.  government  and its agencies and  short-term  securities,  during the year
ended August 31, 1997,  aggregated  $85,565,249 and  $89,916,289,  respectively.
There were no purchases or sales of obligations  of the U.S.  government and its
agencies during the year ended August 31, 1997.

   The cost of  investments  owned at  August  31,  1997  (including  the  joint
repurchase  agreement) for federal income tax purposes was  $159,024,417.  Gross
unrealized  appreciation and depreciation of investments  aggregated $14,610,395
and  $4,542,393  respectively,  resulting  in  net  unrealized  appreciation  of
$10,068,002.

NOTE D --
RECLASSIFICATION OF ACCOUNTS
During the year ended  August 31,  1997,  the Fund has  reclassified  amounts to
reflect a decrease in  accumulated  net realized loss on investments of $459, an
increase to  distributions  in excess of net investment  income of $5,229 and an
increase in capital paid-in of $4,770.  This represents the amount  necessary to
report these balances on a tax basis,  excluding certain temporary  differences,
as of August  31,  1997.  Additional  adjustments  may be  needed in  subsequent
reporting  periods.  These  reclassifications,  which  have no impact on the net
asset value of the Fund, are primarily  attributable  to certain  differences in
the  computation  of  distributable  income and capital  gains under federal tax
rules versus generally accepted  accounting  principles.  The calculation of net
investment  income  per  share  in  the  financial   highlights  excludes  these
adjustments.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT  AUDITORS 
To the Board of Trustees and Shareholders of 
John Hancock Tax-Free Bond Trust --
   John Hancock High Yield Tax-Free Fund

We have audited the accompanying statement of assets and liabilities of the John
Hancock  High  Yield   Tax-Free  Fund  (the  "Fund"),   one  of  the  portfolios
constituting  John  Hancock  Tax-Free  Bond  Trust,  including  the  schedule of
investments,  as of August 31, 1997, and the related statement of operations for
the year ended,  and the  statement  of changes in net assets and the  financial
highlights for each of the periods indicated therein. These financial statements
and financial  highlights are the responsibility of the Fund's  management.  Our
responsibility  is to  express  an opinion  on these  financial  statements  and
financial highlights based on our audits.

   We  conducted  our audits in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our  procedures  included  confirmation  of securities  owned as of
August 31, 1997, by  correspondence  with the  custodian and brokers,  and other
auditing  procedures when replies from brokers were not received.  An audit also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

   In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material  respects,  the financial  position of the
John Hancock High Yield  Tax-Free  Fund of John Hancock  Tax-Free  Bond Trust at
August 31, 1997, the results of its operations for the year then ended,  and the
changes in its net assets and the financial highlights for each of the indicated
periods, in conformity with generally accepted accounting principles.

                               Chairman's Message

DEAR FELLOW SHAREHOLDERS:

The Taxpayer  Relief Act of 1997 recently  signed into law by President  Clinton
includes new twists and important changes to Individual Retirement Account (IRA)
laws. The provisions will, among other things,  allow more people to qualify for
annual  tax-deductible IRA contributions and to save tax-free for college.  They
also allow IRA investors to withdraw money  penalty-free  from all IRAs to buy a
first home or pay for college expenses.

   For existing  deductible  IRAs,  the law doubles  income limits over the next
eight to 10 years for those eligible to deduct an annual IRA  contribution of up
to $2,000.  For individuals,  the annual income cap will increase  incrementally
from the  current  $25,000 to  $50,000 by 2005.  For  couples,  the limit  would
increase from $40,000 today to $80,000 in 2007.  The new law allows  non-working
spouses to make IRA  contributions  even if their spouse is covered by a pension
plan at work, provided the couple's joint income is less than $150,000.

   The law also creates two new IRA investment  vehicles.  One, called the "Roth
IRA" after its principal congressional sponsor, allows for non-deductible annual
contributions up to a $2,000 maximum. But income accumulates tax-free and if the
account has been open for five  years,  distributions  are  tax-free if they are
used after age 591/2 or upon death,  disability or a first-time  home  purchase.
Withdrawals for higher-education expenses would not be subject to a 10% penalty.
Eligible investors must earn less than $95,000 per year individually or $150,000
per couple.

   A second  new IRA plan is  called  the  "Education  IRA"  which  allows  non-
deductible  contributions  of up to $500  per  year,  per  child  under  age 18.
Earnings in the account accumulate tax-free,  and withdrawals are also not taxed
when applied toward undergraduate or graduate-level expenses. Eligible investors
are subject to the same income restrictions as the Roth IRA.

   The law has also made some  important  changes in capital gains tax rates and
estate tax laws. But the devil is in the details,  and so we recommend exploring
how you can benefit from the changes with your investment  professional  and tax
advisor.  The Taxpayer  Relief Act of 1997 gives  investors  new options  toward
savings. It's a move we applaud.

Sincerely,

/s/ Edward J. Boudreau, Jr.

                            fuel municipal bond rally
                            -------------------------

Powered by a number of  favorable  factors,  municipal  bonds turned in a strong
performance  during  the  past 12  months.  The  most  important  factor  aiding
municipal bonds was the lack of inflationary pressure.  Inflation is the bugaboo
of bond  investing  because  it eats away at the  value of  bonds'  fixed-income
payments.  At times  during the past year,  bond  investors  were  worried  that
stronger-than-expected  economic reports would mean that inflation was in danger
of heating up.  Moreover,  investors feared that the Federal Reserve Board would
be  forced to raise  interest  rates as a  pre-emptive  strike.  When  inflation
worries  were at their peak -- as they were  during  much of the first  calendar
quarter of 1997 -- bond investors sent bond prices lower and bond yields higher.
But after this bout of hand  wringing and a small rate hike by the Fed, the bond
markets  staged an impressive  rally that began in late spring and lasted almost
to the end of the  period.  Not only was there  evidence  that the  economy  was
growing at a non-inflationary  pace, but fears of rising interest rates were put
to rest when Fed Chairman Alan Greenspan  strongly suggested to Congress in July
that no further rate hikes were on the near-term horizon.

"Municipals got other good news on the legislative and technical fronts."

   Municipals got other good news on the legislative and technical  fronts.  The
past year saw the death of major support for a federal flat tax. If enacted, the
flat tax would have wiped out the tax-exempt  advantage of municipal  bonds. And

the amount of the total  supply of  municipal  bonds  available  was  adequately
digested by somewhat stronger demand for them.

A look at performance
Against  that  backdrop,  John  Hancock  Tax-Free  Bond  Fund  turned in a solid
performance  for the year.  For the 12 months ended August 31, 1997,  the Fund's
Class  A  and  Class  B  shares   posted  total  returns  of  9.44%  and  8.63%,
respectively, at net asset value. That compared favorably to the average general
municipal bond fund's 8.83% return,  according to Lipper  Analytical  Services.1
Please see pages six and seven for longer-term performance information.

   Several factors  contributed to the Fund's  better-than-average  performance.
First was our relatively heavy weighting in investment-grade  bonds rated BBB by
Standard & Poor's.  Throughout the past year,  these  lower-rated  bonds were in
great demand among investors,  primarily because they offered higher yields than
bonds  rated A or higher.  However,  we've done some  recent  pruning  among our
BBB-rated holdings.  In our view, there is a risk that the economy could weaken,
especially given current economic conditions in parts of Europe and Asia. If the
U.S. economy falters in response,  lower-rated bonds -- which are more sensitive
than  higher-rated  securities to economic weakness -- could suffer. In light of
that outlook,  we felt it prudent to pare some of our lower-rated  holdings at a
time period when their prices were quite good. Even after those sales,  however,
the Fund remained  overweighted  in relatively  high-yielding,  BBB-rated  bonds
compared to its peers.  Another  factor that worked in the Fund's  favor was our
stake in non-callable securities, which can't be redeemed by their issuer before
maturity.  Municipalities,  like homeowners,  often like to refinance their debt
when interest rates fall. When they call away -- or refinance -- their debt when
rates fall, bondholders may be forced to find replacement bonds that offer lower
interest rates.  Because they can't be redeemed prior to maturity,  non-callable
bonds tend to perform  better than their  callable  counterparts  when  interest
rates are on the decline.

   In response to changing market conditions, and depending on our view of where
interest rates were headed,  we adjusted the Fund's duration.  Duration measures
how  sensitive a bond's  price,  and  therefore  the Fund's share  price,  is to
changes in interest  rates.  The longer the duration,  the more  sensitive;  the
shorter, the less sensitive.  Our duration was relatively long during the spring
and summer, which was a generally a

positive given the market's rally as interest rates fell.

Winners and losers
As we mentioned previously, many of our BBB-rated holdings did quite well during
the period. One example was bonds issued by the Port Authority of New York for a
co-generation  plant  used to  provide  energy  and  heat  for  the  authority's
terminals.  Strong demand for all types of New York uninsured  bonds helped send
these  holdings  higher.  Houston  Airport bonds issued on behalf of Continental
Airlines did well as the company's financial picture improved.  Finally, Araphoe
County,  Colorado  bonds -- which  are used to fund a  highway  surrounding  the
Denver Airport -- were advance refunded. In an advance refunding, an issuer with
existing  bonds will issue a second  set of bonds.  Proceeds  from this sale are
then invested in U.S. Treasury securities,  and these Treasuries then secure the
original  bonds  until  their  call  date.   Because  they  are  backed  by  the
highest-quality  Treasury  bonds,  the  refunded  municipals  experience  credit
quality improvement, and in this case, price appreciation.

   Our disappointments were limited to a very small holding in a paper recycling
plant, which suffered when the price of paper remained low during the period.

"In our view, the bond markets are poised to continue their climb."

Outlook
The bond market could continue to experience  bouts of volatility  over the near
term as investors try to sort out various economic reports -- which may prove to
be  contradictory  at times -- and what  they  portend  for  interest  rates and
inflation.  But our longer-term  view is that bonds are poised to continue their
climb. The deflationary  pressures that have curtailed economic growth in Europe
and Asia could  ultimately  translate into slower  economic growth in the United
States.  If the American  economy  shows signs of slowing,  the Federal  Reserve
Board would have the luxury of lowering  interest rates.  Since bond prices move
in the opposite  direction of interest rates,  falling rates could prompt a bond
rally.  We also believe  that there are strong  underpinnings  to the  municipal
market.  Supply, which has been stronger so far in 1997 than it was in preceding
years, continues to be easily absorbed by demand.

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

The tables on the right show the cumulative total returns and the average annual
total  returns  for the John  Hancock  Tax-Free  Bond  Fund.  Total  return is a
performance  measure  that  equals  the  sum of all  income  and  capital  gains
distributions,  assuming reinvestment of these distributions,  and the change in
the price of the Fund's  shares,  expressed  as a  percentage  of the Fund's net
asset value per 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.  Performance  is affected by a 12b-1 plan.
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.

   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. Also note that
capital gains are taxable.

                    John Hancock Funds - Tax-Free Bond Fund


NOTE A --
ACCOUNTING POLICIES
John  Hancock  Tax-Free  Bond  Trust (the  "Trust")  is a  diversified  open-end
management  investment  company  registered under the Investment  Company Act of
1940.  The Trust  consists of two series:  John Hancock  Tax-Free Bond Fund (the
"Fund") and John Hancock High Yield Tax-Free Fund. The other series of the Trust
is reported in separate financial  statements.  The investment  objective of the
Fund is to provide as high a level of interest income exempt from federal income
taxes as is consistent with  preservation  of capital by investing  primarily in
municipal  bonds,  notes and commercial  paper,  the interest on which is exempt
from federal income taxes. 

   The Trustees have  authorized  the issuance of multiple  classes of shares of
the Fund,  designated  as Class A and Class B shares.  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,
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
investment,  to its shareholders.  Therefore, no federal income tax provision is
required.  For federal income tax purposes,  the Fund has $15,619,534 of capital
loss carryforwards  available, to the extent provided by regulations,  to offset
future net realized capital gains. To the extent such  carryforwards are used by
the Fund, no capital gains  distribution will be made. The carryforwards  expire
as follows:  August 31, 2002 --  $10,378,466,  August 31, 2003 -- $5,155,633 and
August 31, 2004 -- $85,435.  The amount expiring August 31, 2004 was acquired on
December 6, 1996 in the merger with John Hancock  Managed  Tax-Exempt  Fund. The
use of this loss to offset future gains may be limited in a given year.

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.

                    John Hancock Funds - Tax-Free Bond 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.

EXPENSES The majority of the expenses of the Trust are directly  identifiable to
an individual  fund.  Expenses which are not readily  identifiable to a specific
fund  are  allocated  in  such  a  manner  as  deemed  equitable,   taking  into
consideration,  among other things,  the nature and type of expense and relative
sizes of the funds.

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.  These agreements  enable
the Fund to participate  with other Funds managed by the Adviser in an unsecured
line  of  credit  with a bank  which  permits  borrowings  up to  $400  million,
collectively.  Interest is charged to each Fund,  based on its  borrowing,  at a
rate equal to 0.50% over the Fed Funds Rate. In addition, a commitment fee, at a
rate of 0.075% per annum based on the average  daily unused  portion of the line
of credit, is allocated among the participating  Funds. The maximum loan balance
during the year for which loans were  outstanding  amounted to $19 million.  The
interest  rate was in the range of 5.94% and 6.06%.  At August 31,  1997,  there
were no outstanding borrowings.

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
Funds gains and/or losses can be affected as a result of futures  contracts.  At
August 31, 1997, open positions in financial futures contracts were as follows:

                                                                 UNREALIZED

   At August 31, 1997,  the Fund has  deposited  $675,000 par value of County of
Clark,   6.50%,   12-01-33  bonds  in  a  segregated  account  to  cover  margin
requirements on open financial futures contracts.

OPTIONS  Listed  options  will be valued at the last  quoted  sales price on the
exchange  on  which  they  are   primarily   traded.   Purchased   put  or  call
over-the-counter  options  will be valued  at the  average  of the "bid"  prices
obtained  from two  independent  brokers.  Written put or call  over-the-counter
options will be valued at the average of the "asked"  prices  obtained  from two
independent  brokers.  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.

                         NOTES TO FINANCIAL STATEMENTS

                    John Hancock Funds - Tax-Free Bond Fund


   The Fund may use  option  contracts  to  manage  its  exposure  to the  price
volatility of financial instruments.  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.

   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  period-end
Statement of Assets and Liabilities.  

   There were no written option transactions for the year ended August 31, 1997.

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 the sum of (a) 0.55% of the first  $500,000,000 of the Fund's
average daily net asset value, (b) 0.50% of the next  $500,000,000 and (c) 0.45%
of the Fund's average daily net asset value in excess of $1,000,000,000.

   The Adviser has voluntarily  agreed to limit the Fund's  expenses  further to
the extent  required to prevent  expenses from exceeding  0.85% and 1.60% of the
average  net  assets   attributable  to  Class  A  and  Class  B,  respectively.
Accordingly,  for the year ended August 31, 1997, the reduction in the Adviser's
fee collectively with any additional  amounts not borne by the Fund by virtue of
the expense limit amounted to $459,575.  This  limitation may be discontinued at
any time.

   The Fund has a  distribution  agreement  with John Hancock  Funds,  Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the year ended August 31,
1997, net sales charges received with regard to sales of Class A shares amounted
to  $642,722.  Out of this  amount,  $65,427 was  retained and used for printing
prospectuses,  advertising,  sales  literature and other purposes,  $169,794 was
paid as sales commissions to unrelated  broker-dealers  and $407,501 was paid as
sales  commissions  to  sales  personnel  of  John  Hancock  Distributors,  Inc.
("Distributors"),  a related broker-dealer.  The Adviser's indirect parent, John
Hancock  Mutual  Life  Insurance  Company  ("JHMLICo"),  is  the  indirect  sole
shareholder of Distributors.

   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  for  providing  distribution  related  services  to the  Fund  in
connection  with the sale of Class B shares.  For the year ended August 31, 1997
the contingent deferred sales charges received by JH Funds amounted to $419,544.

   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 for
distribution  and service  expenses,  at an annual  rate not to exceed  0.25% 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
agreed to limit the  distribution and service fees pursuant to Class A and Class
B plans to 0.15% and 0.90% of the average daily net assets, respectively.  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 Funds. The compensation for the year was
at an annual rate of less than 0.02% of the average net assets of the Fund.

   Mr. Edward J. Boudreau,  Jr., Ms. Anne C. Hodsdon and Mr. Richard S. Scipione
are directors  and/or officers of the Adviser and/or its affiliates,  as well as
Trustees of the Fund. The compensation of 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 another  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  August  31,  1997 the  Fund's  investments  to cover  the  deferred
compensation liability had unrealized appreciation of $4,423.

NOTE C --
INVESTMENT TRANSACTIONS 
Purchases and proceeds from sales of securities,  other than  obligations of the
U.S.  government  and its agencies and  short-term  securities,  during the year
ended August 31, 1997, aggregated  $357,615,898 and $419,388,809,  respectively.
There were no purchases or sales of obligations  of the U.S.  government and its
agencies during the year ended August 31, 1997.

   The cost of  investments  owned at August  31,  1997 for  federal  income tax
purposes was  $742,638,643.  Gross  unrealized  appreciation and depreciation of
investments aggregated $69,294,777 and $2,589,262 respectively, resulting in net
unrealized appreciation of $66,705,515.

NOTE D --  
REORGANIZATION  
On May 2, 1996, the shareholders of John Hancock Tax-Exempt Income Fund (JHTEIF)
approved a plan of reorganization  between JHTEIF and the Fund providing for the
transfer of  substantially  all of the assets and  liabilities  of JHTEIF to the
Fund in  exchange  solely  for  Class A and  Class B  shares  of the  Fund.  The
acquisition  was  accounted  for as a tax-free  exchange of  45,353,943  Class A
shares,  and  903,108  Class B shares of the Fund for the net  assets of JHTEIF,
which  amounted  to  $460,732,563  and  $9,174,769  for  Class  A and B  shares,
respectively,  including $14,942,866 of unrealized appreciation, after the close
of business on May 3, 1996.

   On November 14, 1996, the  shareholders  of John Hancock  Managed  Tax-Exempt
Fund  (JHMTE)  approved  a plan of  reorganization  between  JHMTE  and the Fund
providing for the transfer of substantially all of the assets and liabilities of
JHMTE to the Fund in exchange solely for Class A and Class B shares of the Fund.
The  acquisition  was accounted for as a tax free exchange of 3,663,041  Class A
shares  and  14,270,326  Class B shares of the Fund for the net assets of JHMTE,
which amounted to $38,514,684 and  $150,045,343  for Class A and Class B shares,
respectively,  including $13,013,699 of unrealized appreciation, after the close
of business on December 6, 1996.

NOTE E --  
RECLASSIFICATION OF ACCOUNTS
During the year ended  August 31,  1997,  the Fund has  reclassified  amounts to
reflect an increase in accumulated net realized loss on investments of $135,179,
an increase in distributions in excess of net investment  income of $214,658 and
an increase in capital paid-in of $349,837. This represents the amount necessary
to  report  these  balances  on  a  tax  basis,   excluding   certain  temporary
differences,  as of August 31,  1997.  Additional  adjustments  may be needed in
subsequent reporting periods. These  reclassifications,  which have no impact on
the net asset  value of the Fund,  are  primarily  attributable  to the  certain
differences in the computation of  distributable  income and capital gains under
federal  tax  rules  versus  generally  accepted  accounting   principles.   The
calculation  of net  investment  income  per share in the  financial  highlights
excludes these adjustments.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS 
To the Board of Trustees and Shareholders of 
John Hancock Tax-Free Bond Trust--
   John Hancock Tax-Free Bond Fund

We have audited the accompanying statement of assets and liabilities of the John
Hancock  Tax-Free Bond Fund (the "Fund"),  one of the  port-folios  constituting
John Hancock Tax-Free Bond Trust,  including the schedule of investments,  as of
August 31, 1997, and the related statement of operations for the year ended, and
the statement of changes in net assets and the financial  highlights for each of
the  periods  indicated  therein.   These  financial  statements  and  financial
highlights are the responsibility of the Fund's  management.  Our responsibility
is to express an opinion on these financial  statements and financial highlights
based on our audits.

   We  conducted  our audits in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our  procedures  included  confirmation  of securities  owned as of
August 31, 1997, by  correspondence  with the  custodian and brokers,  and other
auditing  procedures when replies from brokers were not received.  An audit also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

   In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material  respects,  the financial  position of the
John Hancock  Tax-Free Bond Fund, of John Hancock  Tax-Free Bond Trust at August
31, 1997, the results of its operations for the year then ended,  the changes in
its net  assets  for each of the two years in the  period  then  ended,  and the
changes in its net assets and the financial highlights for each of the indicated
periods, in conformity with generally accepted accounting principles.
