A group of young Maori teenagers doing a Haka for their pastor's 61 birthday.

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.

In this video they celebrate their youth leader's birthday and honor him with a haka
