Tamatea Urehaea also known as Tamatea Pōkai-whenua and Tamatea Pōkai-moana was a Māori ariki (chieftain) of the Tākitimu tribal confederation and ancestor of the Ngāti Kahungunu iwi, who probably lived in the fifteenth century. He is famous as an explorer who circumnavigated both islands of New Zealand. After he was expelled from his base at Kaitaia, he settled in Hawke's Bay, but continued to explore the North Island.

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.
