New Zealander seen in khaki windcheater (4)
I believe the answer is:
'new zealander' is the definition.
(informal term for someone from New Zealand)
'in khaki windcheater' is the wordplay.
'in' says the answer is hidden in the clue.
'KIWI' is hidden in the letters of 'khaki windcheater'.
'seen' acts as a link.
(Other definitions for kiwi that I've seen before include "Fruit and flightless bird", "'Fruit, bird and NZ rugby player (4)'", "Someone from New Zealand?", "Rutherford was one", "New Zealander's bird".)
