Hako are the original inhabitants of the Hauraki rohe descending from Toi-te-Huatahi. It is through whakapapa and intermarriage that Te Arawa, Tainui and other tribes established their place in this area. Among the descendants of Hako are high ranking women with whom strong political alliances were forged such as Irakau, Hineurunga and Paremoehau (the wives of Marutūahu), Ruawehea (the wife of Tamaterā), Tauhākari and Tukutuku (the wives of Pāoa), Te Uira and Tuhiao (connections to Tokanui and Tara).
