The haka (plural haka, as in Māori, so in English) is a traditional 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.
The New Zealand sports teams' practice of performing a haka before their international matches has made the haka more widely known around the world. This tradition began with the 1888–89 New Zealand Native football team tour and has been carried on by the New Zealand rugby team since 1905, and rugby league team since 1907.
Although the use of haka by the All Blacks rugby union team and the New Zealand rugby league team has made one type of haka familiar, it has led to misconceptions.
Most haka are performed by men. There are however some haka which are performed predominantly by women – one of the most well-known being the Ngāti Porou haka "Ka Panapana".
In modern times, various haka have been composed to be performed by women and even children. Haka are performed for various reasons: for welcoming distinguished guests, or to acknowledge great achievements, occasions or funerals.
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.
