Ngāti Toa, Ngāti Toarangatira or Ngāti Toa Rangatira, is a Māori iwi (tribe) based in the southern North Island and in the northern South Island of New Zealand. Its rohe extends from Whanganui in the north, Palmerston North in the east, and Kaikōura and Hokitika in the south. Ngāti Toa remains a small iwi with a population of only about 9000. 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 north of the South Island. Ngāti Toa's governing body has the name Te Rūnanga o Toa Rangatira.
