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.

[2] He was disqualified from the Legislative Council in August 1880 over a technicality, which caused bitterness and resentment among Māori.

When appointed by Sir George Grey, Taiaroa held (and continued to hold) a salaried (government) office, hence was not eligible to sit in the council, despite having attended three sessions.

[3] He was drawing a salary as a Native Assessor[4] and it was suggested that a Validation Act would have been passed for a European member in that situation.

[1] Taiaroa then held the electorate from 1881 to 1885 when he was again appointed to the Legislative Council, where he served for 20 years until his death.
