New Zealand flightless bird (4)

I believe the answer is:
kiwi
'new zealand flightless bird' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for kiwi that I've seen before include "one with big bill" , "Flightless NZ bird" , "Someone from Auckland?" , "'Fruit, bird and NZ rugby player (4)'" , "N Zealand bird" .)
