Wander around island, finding NZ native (5)
I believe the answer is:
maori
'nz native' is the definition.
(I've seen this before)
'wander around island' is the wordplay.
'wander' becomes 'roam' (synonyms).
'around' says the letters should be written backwards.
'island' becomes 'i' (geographical abbreviation).
'roam' written backwards gives 'maor'.
'maor'+'i'='MAORI'
'finding' acts as a link.
(Other definitions for maori that I've seen before include "Native Kiwi" , "antipodean language" , "NZ people" , "Indigenous New Zealanders" , "Member of New Zealand's aboriginal people" .)
