A New Zealander (4)
I believe the answer is:
kiwi
'a new zealander' is the definition.
(informal term for someone from New Zealand)
This is the entire clue.
(Other definitions for kiwi that I've seen before include "'Fruit, bird and NZ rugby player (4)'" , "Fruit and flightless bird" , "N Zealand bird" , "Someone from Auckland?" , "Flightless NZ bird" .)
