Wiremu Piti Pomare

Wiremu Piti Pōmare (? – 29 January 1851) was a chief of Ngāti Mutunga, a Māori iwi originally of Taranaki, then of the Wellington region, then the Chatham Islands, in New Zealand. He was often known as Pōmare Ngātata, taking the name Wiremu Piti when he was baptised a Christian in 1844.

Pōmare's birth date is not known; he was about 30 in 1834, according to information collected by Percy Smith. and they were already at odds with Te Rauparaha's hapū for other reasons. Pōmare's brother Te Waka Tīwai was killed in the battle. After he was buried, Tawhiti's brothers dug up the grave, enraging Pōmare, who sent his wife back to her tribe, along with their two youngest children, keeping just the eldest child himself. Around this time he married Hera Waitaoro, daughter of Te Manu Toheroa (or Te Manu-tohe-roa) of the Puketapu hapū of Te Āti Awa.

Anxious about relations with Ngāti Toa after the battle of Haowhenua and Pōmare's marriage breakup, Ngāti Mutunga and Ngāti Tama (which had its own quarrels with Ngāti Toa) left Wellington and migrated to the Chatham Islands in 1835. The forced settlement of the archipelago resulted in significant violence, with much of the extant local population (the Moriori) killed or enslaved by the invaders. Pōmare became the leading Ngāti Mutunga chief about 1836–1837. He returned to Wellington in 1842 and was baptised by Octavius Hadfield at Waikanae on 7 April 1844, taking the Christian name Wiremu (Wi) Piti (a transliteration of William Pitt). He returned to the Chatham Islands and died there on 29 January 1851. He was succeeded as leader of Ngāti Mutunga by his nephew Wiremu Naera Pōmare.
