Manunui (Māori manu nui or "big bird") is a small Whanganui River settlement, about 6 kilometres (3.7 mi) east of Taumarunui on State Highway 4, in New Zealand's King Country. It was once known as Waimarino, but John Burnand of the Ellis and Burnand sawmilling firm renamed it Manunui around 1905. Manunui is the home of the Ngāti Hinemihi and Ngāti Manunui hapū of the iwi Ngāti Tūwharetoa. Their Maniaiti Marae and Te Aroha o Ngā Mātua Tūpuna meeting house also have affiliations with the Ngāti Hāua hapū of Ngāti Hekeāwai and Ngāti Hāua, and with the Ngāti Tūwharetoa.
