Henry William Petre (1820 – 3 December 1889) was colonial treasurer of New Munster Province.
He was a member of the New Zealand Legislative Council from 31 December 1853 to 6 November 1860, when he was disqualified for absence.
His father sent for Mary Ann Eleanor Walmsley, then 15 years old and brought up in a convent, and the wedding happened in 1842.
[5] Petre lived in the Hutt Valley, and with Vavasour and Charles Clifford established a sheep station in the Wairarapa.
[8] He seems to have been a man of strange appearance, from the description by his contemporary, the New Zealand social commentator Charlotte Godley: "He is immensely tall and thin and looks like a set of fire irons badly hung together".
