Hākiro was the son of Tāreha, and, like his father, was from Kororāreka (Russell). He had contact with both Catholic (Bishop Pompallier) and Protestant (Henry Williams) missionaries before 1840. British Resident James Busby claimed that Hākiro had suggested that he (Busby) might be a king for Māori.
During the debate about the treaty at Waitangi on 5 February 1840, Hākiro spoke on behalf of Tītore, who had signed the Declaration of Independence in 1835 and died in 1837. He argued strongly against the treaty and Governor William Hobson: ‘“To thee, O Governor! this. Who says ”Sit“? Who? Hear me, O Governor! I say, no, no.’ As he shouted these rhetorical questions and answers he ran swiftly backwards and forwards brandishing a taiaha (fighting staff). ’Sit, indeed! Who says, ”Sit”? Go back, go back; do not thou sit here. What wilt thou sit here for? We are not thy people. We are free. We will not have a Governor. Return, return; leave us. The missionaries and Busby are our fathers. We do not want thee; so go back, return, walk away.”’ [1] However, Hākiro did sign the treaty on 6 February.
On 11 Februrary 1858 Hākiro was one of the speakers who welcomed Governor Thomas Gore Browne to Waimate, in the Bay of Islands, noting that he supported Queen Victoria.
