Maori dance (4)
I believe the answer is:
haka
'maori dance' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for haka that I've seen before include "routine before start of match" , "Maori ceremonial war-dance" , "Aggressive Kiwi dance before a rugby match" , "pre-match ritual" , "Maori war dance used by All Blacks" .)
