     Re:  Nicholas-Applegate Institutional Funds (the "Trust" or "Registrant")
          Amendment to Form N-1A
          Registration Statement
          File Nos. 333-71469 and 811-07384
          CIK No. 0000895414

Dear Mr. O'Connor

     Pursuant to our telephone conversation, the Trust hereby submits this
application for withdrawal of  Post-Effective Amendment No. 19 to its
Registration Statement on Form N-1A together with all exhibits filed on
February 13, 2004 (the "Amendment"") pursuant to Rule 477(a) of the
Securities Act of 1933 (the "Act").

     The Amendment is being withdrawn as the Trust wishes to amend it to add
Class IV shares of the Emerging Markets Opportunities Series of the Trust
which were inadvertently omitted from the filing.

     Post-Effective Amendment No. 19 will become effective pursuant to Rule
485(a) on April 28, 2004.  Please issue an order with respect to this
application for withdrawal as soon as possible.

     Pursuant to the requirements of Rule 478 of the Act, this application
for withdrawal of the Amendment has been signed by the President of the Trust
this 16th day of March 2004.
