Tawarau signed the East Coast sheet of the Treaty of Waitangi between 5 and 12 May 1840 at Tūranga (now Gisborne). He was a rangatira (chief) of the Te Whānau-a-Taupara and Te Whānau-a-Kai hapū (subtribes) of Te Aitanga-a-Māhaki.
This may have been Marae Tawarau, a signatory to the sale of the Poverty Bay Blocks in 1868.
