Maori performers doing the haka (war dance) at Melbourne Festival, Australia

The Haka is a traditional ancestral war cry, dance, or challenge from the Māori people of New Zealand. It is a posture dance performed by a group, with vigorous movements and stamping of the feet with rhythmically shouted accompaniment. War haka were originally performed by warriors before a battle, proclaiming their strength and prowess in order to intimidate the opposition, but haka are also performed for various reasons: for welcoming distinguished guests, or to acknowledge great achievements, occasions or funerals, and kapa haka performance groups are very common in schools. War haka (peruperu) were originally performed by warriors before a battle, proclaiming their strength and prowess in order to intimidate the opposition. Today, haka constitute an integral part of formal or official welcome ceremonies for distinguished visitors or foreign dignitaries, serving to impart a sense of the importance of the occasion.
