Tauāmanaia, who was sometimes known as Toua, signed the East Coast sheet of the Treaty of Waitangi between 5 and 12 May 1840 at Tūranga (now Gisborne). He was a Rongowhakaata rangatira (chief).
He may have been Hore Tauamanaia, who attended a Pai Mārire (Hauhau) meeting at Whare Whakairo that was called to decide whether to go to war with Henry Potae.
