Except for minor damage, the college was spared by the Christchurch earthquakes. As a result of the 22 February earthquake in 2011, Catholic Cathedral College relocated to St Thomas of Canterbury College and "site shared". The reason for this was that although it was not significantly damaged, parts of Catholic Cathedral College were under the unstable 400-ton dome of the Christchurch Catholic Cathedral. Because the dome was in imminent danger of collapse, the college had to move. St Thomas' restricted its own use of the school to the morning and Catholic Cathedral College took over the school in the afternoon. The dome was removed on 26 July and Catholic Cathedral College moved back to its own site on 1 August 2011.
