Ngāti Kahungunu ki Wairarapa 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 the rohe (tribal area) north of the Remutaka Range in the Wairarapa geographic region.[3]
Ngāti Kahungunu ki Wairarapa is one of six divisions within the tribe. Ngāti Kahungunu ki Tamakinui a Rua is located immediately north. Ngāti Kahungunu ki Heretaunga, Ngāti Kahungunu ki Tamatea, Ngāti Kahungunu ki Te Whanganui-a-Orotu and Ngāti Kahungunu ki Te Wairoa are located further north. The Wairoa, Heretaunga and Wairarapa divisions are traditionally larger than the other three divisions.
