Ngāti Apa is a Māori iwi (tribe) in Rangitikei District of New Zealand.

[1] Its rohe (traditional tribal lands) extend between the Mangawhero, Whangaehu, Turakina and Rangitīkei rivers.

The marae in this district include Tini wai tara, Whangaehu, Kauangaroa, and Parewanui.

To the west of Pūtauaki mountain is a place known to Māori as Te Takanga-a-Apa (the place where Apa fell), so named because, according to one account, it was where Apa was kicked to the ground by the pet moa of a man called Te Awatope.

Apa started sending parts of his tribe south to cultivate the land and have settlements ready before the whole party travelled down.
