Te Uri-o-Hau is a Māori iwi (tribe) of the greater Ngāti Whātua confederation. While some have considered it to be merely a hapū (subtribe) of Ngāti Whātua, Te Uri-o-Hau can act independently of the other 3 principle iwi of the Ngāti Whātua Confederation (Ngāti Whātua-o-Ōrākei, Te Roroa and Te Taoū). Te Uri-o-Hau itself has hapū within it. Its rohe (area) includes Dargaville, Maungaturoto, Mangawhai, Kaiwaka, Wellsford and the Kaipara Harbour. In 2018 it was estimated 1,314 people were affiliated to the iwi, based on 2018 New Zealand Census data.
