Ngāti Whātua is a Māori iwi (tribe) of the lower Northland Peninsula of New Zealand's North Island. It comprises a confederation of four hapū (subtribes) interconnected both by ancestry and by association over time: Te Uri-o-Hau, Te Roroa, Te Taoū, and Ngāti Whātua-o-Ōrākei. The four hapū can act together or separately as independent tribes.

Te Uri-o-Hau is a Māori iwi (tribe) based around New Zealand's Kaipara Harbour. It is both an independent iwi and a hapū (sub-tribe) of the larger Ngāti Whātua iwi, alongside Ngāti Whātua-o-Ōrākei, Te Roroa and Te Taoū. Its rohe includes Dargaville, Maungaturoto, Mangawhai, Kaiwaka and Wellsford.
