Ngāti Mutunga descends from a number of ancestors who lived in the area occupied today by ngā uri o ngā tūpuna o Ngāti Mutunga. These ancestors include Tokauri, Tokatea, Mihirau, Heruika, Pūrakino, Rakaupounamu, Uenuku (son of Ruawahia), Hineweo, Hineno, Te Hihiotū, Kahukura and Mutunga.
Ngāti Mutunga also descends from ancestors who arrived on the Tokomaru, Tahatuna and Ōkoki waka such as Taitaawaro, Manaia and Ngānganarūrū. Over generations the descendants of these tūpuna inter-married and became generally known as Ngāti Mutunga.
It is difficult to determine how many Ngāti Mutunga people there are. Our Taranaki rohe was once densely populated with many kainga and pā. A number of factors such as warfare and migration, loss of land through wrongful Crown confiscation, and urban migration led to a decline in the population identifying as Ngāti Mutunga during the nineteenth and twentieth centuries.
Today our sole remaining marae is located in Urenui, a small seaside village located approximately 32 km north of New Plymouth and 20 km north of Waitara.
Like most Iwi, Ngāti Mutunga now has members spread far and wide. The main concentrations of Ngāti Mutunga populations are located within Taranaki, Christchurch and Wellington. The majority of Ngāti Mutunga descendants (approximately 73%) live outside Taranaki.
