Ngāti Kahungunu ki Tamatea is a tribal division within the Māori iwi (tribe) of Ngāti Kahungunu in the south-east of New Zealand's North Island.[2] It consists of a number of hapū (sub-tribes) located within a rohe (tribal area) predominantly within the Central Hawke's Bay District.[3]
Ngāti Kahungunu ki Tamatea is one of six divisions within the tribe. Ngāti Kahungunu ki Te Wairoa, Ngāti Kahungunu ki Te Whanganui-a-Orotu and Ngāti Kahungunu ki Heretaunga are located to the north. Ngāti Kahungunu ki Tamakinui a Rua and Ngāti Kahungunu ki Wairarapa are located to the south. The Wairoa, Heretaunga and Wairarapa divisions are traditionally larger than Tamatea and the other two divisions.
