Ngāti Kahungunu ki Heretaunga is a tribal division within the Māori iwi (tribe) of Ngāti Kahungunu in New Zealand's Hawke's Bay Region.[2] It consists of a number of hapū (sub-tribes) located within the rohe (tribal area) east of Hawke Bay, mostly within the modern day Hastings District.[3]
Ngāti Kahungunu ki Heretaunga is one of six divisions within the tribe. Ngāti Kahungunu ki Te Wairoa, Ngāti Kahungunu ki Te Whanganui-a-Orotu are located to the north. Ngāti Kahungunu ki Tamatea, 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 the other three divisions.
