Polynesians are an ethnolinguistic group of closely related ethnic groups who are native to Polynesia, an expansive region of Oceania in the Pacific Ocean. They trace their early prehistoric origins to Island Southeast Asia and form part of the larger Austronesian ethnolinguistic group with an Urheimat in Taiwan. They speak the Polynesian languages, a branch of the Oceanic subfamily of the Austronesian language family. The Indigenous Māori people constitute the largest Polynesian population, followed by Samoans, Native Hawaiians, Tahitians, Tongans and Cook Islands Māori.

Māori are the indigenous Polynesian people of mainland New Zealand. Māori originated with settlers from East Polynesia, who arrived in New Zealand in several waves of canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed their own distinctive culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some early Māori moved to the Chatham Islands, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori.
