Or am I perhaps a New Zealander? (5)
I believe the answer is:
maori
'a new zealander?' is the definition.
(the Maori are indigenous people of New Zealand)
'or am i perhaps' is the wordplay.
'perhaps' indicates an anagram.
'or'+'am'+'i'='orami'
'orami' with letters rearranged gives 'MAORI'.
(Other definitions for maori that I've seen before include "NZ people" , "Native of New Zealand and the Cook Islands" , "Let it stand" , "native person" , "aboriginal inhabitant" .)
