Marcellin College is an integrated, co-educational college in Royal Oak, Auckland, New Zealand for students in Year 7 to Year 13. Marcellin College was founded by the Marist Brothers in 1958 as a secondary school for boys only. The school is located on spacious grounds which were formerly part of the Pah estate. Most of the former Pah estate contiguous with Marcellin College is now owned by the Auckland City Council and is maintained as a park known as "Monte Cecilia Park" (largely located in the suburb of Hillsborough). In 1982 the proprietor of Marcellin College signed an integration Agreement with the Minister of Education and the college entered the State education system. However, it entered the state system as a co-educational secondary school because in 1980 the school had incorporated the secondary department of a school for girls, St Benedict's College, Newton, which closed in that year. St Benedict's College had its origins in 1884 when the Sisters of St Joseph of the Sacred Heart, at the behest of their founder, Mary MacKillop (St Mary of the Cross), arrived in Auckland from Adelaide and opened their first school in a converted shop in Karangahape Road.
