Poi is a form of juggling, or object manipulation with balls on ropes, hel in the hands and swung in various circular patterns, comparable to club-twirling. It originated with the Māori people of New Zealand (the word poi means "ball" in Māori). Women and men used it to increase flexibility, strength, and coordination. It developed into a traditional performance art practiced mostly by women. This art, in conjunction with others including waiata a ringa, haka and titi torea, make up the performance of kapa haka (Māori culture groups).
