Kuranui College is a state co-educational secondary school in Greytown, New Zealand. It is the only secondary school in the South Wairarapa District, and serves the towns of Greytown, Featherston, Martinborough, and the majority of Carterton. The college was opened in February 1960, replacing three district high schools in Greytown, Featherston, and Martinborough. Built to the Nelson plan, it was designed to take up to 900 students in the midst of the post-World War II baby boom. It has been said to have as many as 1000 students in the mid-1970's, but since the end of the baby boom, has since dropped back to around the present level of 482. The name Kuranui in the Maori language means "'large school" (kura = school of education + nui = big, large), describing the aspect it was formed from three former high schools, and also being a secondary school ("bigger" than a primary school.). The school has had four principals - O. Sam Meads (1960-); Peter Werry; Joye Halford; and R. Grey Tuck (1998-2008). Geoff Shepherd, the then deputy principal, superseded Grey Tuck as principal of Kuranui in May 2008.
