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 and there was also some cooperation with Shirley Boys' High School which is 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 for a period expected to be between two and four years. On 15 March 2019, Marian College announced the site for a new location on Lydia Street in Northcote, to be opened in 2023.
