Polynesian language
I believe the answer is:
maori
'polynesian language' 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 "NZ people" , "One of New Zealand's aboriginal people" , "I roam with New Zealander" , "NZ aboriginal" , "Native of New Zealand and the Cook Islands" .)
