Te Heuheu Tukino IV (Horonuku, Pataatai) (1821-1888) was paramount chief of the Ngāti Tuwharetoa, a Māori tribe of the central North Island of New Zealand. His birth name was Pataatai but he assumed the name Horonuku - meaning landslide - after the death of his parents in a landslide in 1846. He was placed under house arrest by the Crown and forced to gift the mountains of Ruapehu, Tongariro and Ngauruhoe in 1887 for the creation of Tongariro National Park.
