St Catherine's College, a Catholic secondary school for girls, operates in the Wellington suburb Kilbirnie in New Zealand. It was founded in 1950 by the Sisters of Mercy. There was formerly a primary school on the site opened by the Sisters of Mercy in 1918. On 30 March 1983, St Catherine's College became an integrated school under the Private Schools Conditional Integration Act of 1975. The Board of Trustees was first elected in 1989 and is responsible for the governance of the College. In recent years a new multi-functional hall, called "Mercy Hall", has been opened as well as a Food Technology Centre, a Music Suite, and a new Design Arts Centre.
