Polynesian country (5)
I believe the answer is:
samoa
'polynesian country' is the definition.
(country in Polynesia, a region of Oceania)
This is all the clue.
(Other definitions for samoa that I've seen before include "Group of volcanic islands in the S Pacific" , "South Pacific island nation" , "island territory" , "South Pacific island country, gaining its independence from New Zealand in 1962" , "Polynesian island group" .)
