Home of the first Dole plantation (4)
I believe the answer is:
oahu
'home of the first dole plantation' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for oahu that I've seen before include "Hawaiian island" , "popular Pacific location" , "Pacific island" , "Chief island of Hawaii" , "Honolulu's island" .)
