Kī-o-Rahi is a traditional Māori game based on the purākau of Rahitutakahina and the rescue of his wife Tiarakurapakewai, played with a small round ball called a kī. Two teams of eight players, kaioma and taniwha, play on a circular field divided into zones, and score points by touching the pou (boundary markers) and hitting a central tupu, or target. The game is played for 4 quarters, generally 6 minutes long, and teams alternate roles of kīoma and taniwha each quarter.

Rules vary from place to place, and the game can be played as a touch or tackle sport. Kī-o-Rahi is derived from ball games played in circular clearings before Europeans arrived in New Zealand.
