St Peter's College is a Catholic secondary school for boys, located in Auckland, New Zealand, in the central city suburb of Grafton. With a roll of over 1300, the school is one of the largest Catholic schools in New Zealand. St Peter's College was established in 1939 as a successor of Auckland's earliest school (1841) and of St Peter's School, founded in 1857. The Outhwaite family, who acquired the land around 1841, donated the site of the college. The Christian Brothers provided staff for the college for 70 years. St Peter's College is the oldest Catholic boys' school in Auckland still on its original site, and with its original name.
