Ngāti Rārua are a Māori tribe (iwi) of the Tainui tribal confederation.
Ngāti Rārua stem from the marriage of Rārua-ioio and Tū-pāhau and, like other Tainui tribes, had their original home in the Waikato, specifically on the west coast of the King Country region, at Kāwhia, Marokopa and Waikawau. In 1821 Ngāti Rārua moved southwards in a series of migrations (heke) led by Te Rauparaha of Ngāti Toa which saw the iwi relocate to Nelson and Marlborough in the upper South Island.
Ngāi Tahu, or Kāi Tahu, is the principal Māori iwi (tribe) of the South Island. Its takiwā (tribal area) is the largest in New Zealand, and extends from the White Bluffs / Te Parinui o Whiti (southeast of Blenheim), Mount Māhanga and Kahurangi Point in the north to Stewart Island / Rakiura in the south. The takiwā comprises 18 rūnanga (governance areas) corresponding to traditional settlements. According to the 2023 census an estimated 84,000 people affiliated with the Kāi Tahu iwi.
Ngāi Tahu originated in the Gisborne District of the North Island, along with Ngāti Porou and Ngāti Kahungunu, who all intermarried amongst the local Ngāti Ira. Over time, all but Ngāti Porou would migrate away from the district. Several iwi were already occupying the South Island prior to Ngāi Tahu's arrival, with Kāti Māmoe only having arrived about a century earlier from the Hastings District, and already having conquered Waitaha, who themselves were a collection of ancient groups. Other iwi that Ngāi Tahu encountered while migrating through the South Island were Ngāi Tara, Rangitāne, Ngāti Tūmatakōkiri, and Ngāti Wairangi – all of which also migrated from the North Island at varying times. During the 19th century, hundreds of thousands of Europeans – mostly British – migrated to New Zealand. After European arrival, Ngāti Toa (allied with Ngāti Tama) and Ngāti Rārua invaded Ngāi Tahu's territory with muskets. Some European settlers intermingled with native iwi populations, and today, most families who descend from Ngāi Tahu also have Ngāti Māmoe and British ancestry.
Te Tau Ihu Māori are a group of Māori iwi in the upper South Island of New Zealand. It includes Ngāti Kuia, Rangitāne, Ngāti Tūmatakōkiri and Ngāti Apa ki te Rā Tō (from the Kurahaupō canoe), Ngāti Koata, Ngāti Rārua and Ngāti Toa (from the Tainui canoe), andNgāti Tama and Te Atiawa o Te Waka-a-Māui (from the Tokomaru canoe of Taranaki).
Ngāti Toa, also called Ngāti Toarangatira or Ngāti Toa Rangatira, is a Māori iwi (tribe) based in the southern North Island and the northern South Island of New Zealand. Ngāti Toa remains a small iwi with a population of about 9,000. The iwi is centred around Porirua, Plimmerton, Kāpiti, Blenheim and Arapaoa Island. It has four marae: Takapūwāhia and Hongoeka in Porirua City, and Whakatū and Wairau in the South Island. Ngāti Toa's governing body has the name Te Rūnanga o Toa Rangatira.
The iwi traces its descent from the eponymous ancestor Toarangatira. Ngāti Toa lived in the Kāwhia region of the North Island until the 1820s, when forced out by conflict with other Tainui iwi, led by Pōtatau Te Wherowhero (c. 1785 – 1860), who later became the first Māori King (r. 1858–1860). Ngāti Toa, Ngāti Rārua and Ngāti Koata, led by Te Rauparaha (c. 1765 – 1849), escaped south and invaded Taranaki and the Wellington regions together with three north Taranaki iwi, Te Āti Awa, Ngāti Tama and Ngāti Mutunga. Together they fought and conquered the people of Wellington, Ngāti Ira, who practically ceased to exist as an independent iwi.After the 1820s, the region conquered by Ngāti Toa extended from Miria-te-kakara at Rangitikei to Wellington, and across Cook Strait to Wairau and Nelson.
Tainui is a tribal waka confederation of New Zealand Māori iwi. The Tainui confederation comprises four principal related Māori iwi of the central North Island of New Zealand: Hauraki, Ngāti Maniapoto, Ngāti Raukawa and Waikato.There are other Tainui iwi whose tribal areas lay outside the traditional Tainui boundaries – Ngāi Tai in the Auckland area, Ngāti Raukawa ki Te Tonga and Ngāti Toa in the Horowhenua, Kāpiti region, and Ngāti Rārua and Ngāti Koata in the northern South Island.
