Marian College, Christchurch

It was decided to merge these schools into a larger Catholic secondary day school for girls which would be an integrated school under the Private Schools Conditional Integration Act 1975 and to develop it on the McKillop College site in North Parade.

Marian College was officially opened on 25 March 1982, the feast of the Annunciation of the Lord.[3] The first principal was Sister Eleanor Capper RSJ who left in 1996.[4] In the subsequent 30 years, Marian College extended its facilities to include an assembly hall/gymnasium, a music suite, library, technology rooms’ and new classrooms. The oldest building was the administration block, which was built in 1914 by a Doctor Louisson and used as a family residence, until it was sold to the Sisters of St Joseph in 1949.[3]

Because of the effects of the 2010 Canterbury earthquake and the 2011 Christchurch earthquake, the school was relocated for the 2011 school year to St Bede's College, Christchurch. There was also some cooperation with Shirley Boys' High School which was near the school.

As a result of the February earthquake and the June 2011 Christchurch earthquake significant liquefaction occurred on the College site resulting in most buildings suffering differential settlement in many areas of up to 215mm. It was therefore decided to relocate the school to the site of Catholic Cathedral College (where there was sufficient surplus capacity to accommodate the school) at 122 Barbadoes Street at the beginning of the 2012 school year. Initially, the College was expected to be accommodated for a period of two to four years.[5] On 15 March 2019, Marian College announced the site for a new location on Lydia Street in Northcote, to be opened in 2023.[6]
