Ladies and Gentlemen:

          We have acted as counsel with respect to federal income tax matters to
Hawaiian Electric Industries, Inc., a Hawaii corporation (the "Company"), the
Hawaiian Electric Industries Capital Trust I, a statutory business trust
organized under the Business Trust Act of the State of Delaware (the "Trust"),
and HEI Preferred Funding, LP, a limited partnership formed under the Delaware
Revised Uniform Limited Partnership Act (the "Partnership"), in connection with
the preparation and filing by the Company, the Partnership and the Trust with
the Securities and Exchange Commission of a Registration Statement on Form S-3
(Registration Nos. 333- 18809,

333-18809-01, 333-18809-02, 333-18809-03, 333-18809-04) (as amended, the
"Registration Statement")/1/ under the Securities Act of 1933 with respect to
(i) the issuance and sale of the Trust Preferred Securities, (ii) the issuance
and sale of the Partnership Preferred Securities, (iii) the issuance and sale of
the Debentures and (iv) the issuance and sale of the Trust Guarantees, the
Partnership Guarantee and the Investment Guarantees.

          In rendering our opinions, we have reviewed and relied upon (i) the
facts set forth in the Registration Statement, (ii) the forms of the Trust
Agreement, the Limited Partnership Agreement, the Trust Securities, the
Partnership Preferred Securities, the Debentures, the Partnership Guarantee, the
Trust Guarantees and the Investment Guarantees, each filed as an exhibit to the
Registration Statement, and (iii) certain representations made by officers of
the Company and certain of its subsidiaries.

          On the basis of the foregoing, and assuming that the Partnership and
the Trust are formed and will be maintained in compliance with the terms of the
Limited Partnership Agreement and the Trust Agreement, respectively, we hereby
confirm (i) our opinions set forth in the Registration Statement under the
caption "Certain Federal Income Tax Considerations" and (ii) that, subject to
the qualifications set forth therein, the discussion set forth in the
Registration Statement under such caption is an accurate summary of the United
States federal income tax matters described therein.

          We express no opinion with respect to the transactions described in
the Registration Statement other than as expressly set forth herein. Moreover,
we note that there is no authority directly on point dealing with securities
such as the Trust Preferred Securities or transactions of the type described
therein, and that our opinions are not binding on the Internal Revenue Service
or the courts, either of which could

them in the Registration Statement.

take a contrary position. Nevertheless, we believe that if challenged, the
opinions set forth in the Registration Statement would be sustained by a court
with jurisdiction in a properly presented case. 

          Our opinions are based upon the Internal Revenue Code of 1986, as
amended, the Treasury regulations promulgated thereunder, and other relevant
authorities, all as in effect on the date hereof. Consequently, future changes
in the law may cause the tax treatment of the transactions referred to herein to
be materially different from that described in the Registration Statement.

          We hereby consent to the use of our name in the Registration Statement
and to the filing of this letter as an exhibit to the Registration Statement.
In giving this consent, however, we do not hereby admit that we are within the
category of persons whose consent is required under Section 7 of the Securities
Act of 1933 and the rules and regulations of the Securities and Exchange
Commission thereunder.


                         Very truly yours,

                         /s/ GOODSILL ANDERSON QUINN & STIFEL
