Ki-o-rahi is a ball sport played in New Zealand with a small round ball called a 'ki'. The game is widely known in Māori communities and in scattered mainstream locations throughout the country. It is a fast-paced sport incorporating skills similar to Australian Rules, rugby union, netball and touch. Two teams of seven players play on a circular field divided into zones, and score points by touching the 'pou' (boundary markers) and hitting a central 'tupu' or target.

In 2005 Ki-o-rahi was chosen to represent New Zealand by global fast-food chain McDonald's as part of its 'Passport to Play' programme to teach physical play activities in 31,000 American schools. The programme will give instruction in 15 ethnic games to seven million primary school children.

The New Zealand Ki-o-rahi representative organisation, Ki-o-Rahi Akotanga Iho, formed with men's and women's national teams, completed a 14 match tour of Europe in September and October 2010. The men's team included 22-test All Black veteran Wayne Shelford who led the team to a 57-10 test win against Ki-o-Rahi Dieppe Organisation, the French Ki-o-Rahi federation. Shelfords ki-o-rahi test jersey made him the first Ki-o-rahi / Rugby double international for NZ. The women's team also won by 33-0. These were the first historic test matches between NZ and France.
