New Zealand bird or fruit (4)
I believe the answer is:
kiwi
I believe this clue is a double definition.
'new zealand bird' is the first definition.
(I've seen this before)
'fruit' is the second definition.
(I know that kiwi is a berry)
(Other definitions for kiwi that I've seen before include "Hairy fruit with green flesh" , "Chinese gooseberry" , "New Zealand bird that does not fly" , "Symbol of New Zealand" , "New Zealander (informal)" .)
