Whatihua was a Māori rangatira (chief) in the Tainui confederation of tribes, based at Kāwhia, New Zealand. He quarrelled with his brother, Tūrongo, and as a result Tainui was split between them, with Whatihua receiving the northern Waikato region, including Kāwhia. He probably lived in the early sixteenth century.

Tūrongo was a Māori rangatira (chief) in the Tainui confederation of tribes, based at Rangiātea, near Waikeria, New Zealand. He quarrelled with his brother, Whatihua, and as a result Tainui was split between them, with Tūrongo receiving the southern Waikato region. His marriage to Māhina-o-rangi created a genealogical link between Tainui and Ngāti Kahungunu of the East Coast, which is still commemorated. He probably lived in the early sixteenth century.
