The islands of New Zealand are the present-day homeland of the Maori. They comprise around 20% of New Zealand’s population.
Archaeologists refer to two branches of Maori: the archaic and the traditional.
The archaic Maori culture dates back to around AD 1000. They are considered as the original inhabitants of New Zealand. They relied on the moa, a large, flightless bird that they hunted into extinction.
The traditional Maori are believed to have migrated to the North Island of New Zealand around the fourteenth century from the Society Islands of Polynesia.
Language: Maori belongs to the Tahitic branch of the Eastern Polynesian language group earlier there were two distinct Maori dialects, North Island Maori and South Island Maori, which is now extinct. Currently, Moari speaks the English language.
Religion: Maori of today are Christian (primarily Anglican, Presbyterian, and Roman Catholic)
