Hōri Kerei Taiaroa (born 1830s or early 1840s – 4 August 1905), also known as Huriwhenua, was a Māori member of the New Zealand parliament and the paramount chief of the southern iwi of Ngāi Tahu. The son of Ngāi Tahu leader Te Mātenga Taiaroa and Mawera Taiaroa, he was born at Ōtākou on the Otago Peninsula in the 1830s or early 1840s. He represented the Southern Maori electorate from 1871 to February 1879, when he appointed to the Legislative Council. He was disqualified from the Legislative Council in August 1880 over a technicality, which caused bitterness and resentment among Māori.
