Tama-i-hara-nui (17?? c. 1830/1831), also known as Te Maiharanui and Tamaiharanui, was a New Zealand Māori chief of Ngāi Tahu.[1] He was described as "strong and ruthless" and was a central figure in the 1820s "kai huanga" feud, meaning "eat relatives".[2] Tama-i-hara-nui angered Ngāti Toa by letting a group of their chiefs into Kaiapoi pā and then killing them. Te Rauparaha, one of the Ngāti Toa chiefs who stayed outside of the , returned to Banks Peninsula in November 1830 and captured Tama-i-hara-nui. He was taken to Ōtaki, where he was tortured by the wives of the chiefs who had been killed at Kaiapoi pā, and then killed himself.[1]
