Indigenous New Zealander (5)
I believe the answer is:
'indigenous new zealander' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for maori that I've seen before include "aboriginal inhabitant" , "A native from the south" , "Polynesian aboriginal" , "Native of New Zealand and the Cook Islands" , "Native Kiwi" .)
