An increase in the College roll resulted in the addition of another House. Purchased in 1975 from the University of Canterbury, it was initially converted into classrooms and the Clothing Pool and then in 1983, with some more renovations, it began a new life as a dayboy House.  

The name Rolleston House was originally given to it when it was Number 4 Hostel for Canterbury College (the predecessor of the University of Canterbury).   It was most appropriate that this continuation of name should occur when it was acquired by Christ’s College.  Not only is it situated on the  Rolleston Avenue corner but also  William Rolleston, sometime Superintendent of Canterbury and Member of the House of Representatives, was at times an examiner of the sixth form in Latin and Greek, and a Fellow of Christ’s College  from 1860-1903.

Rolleston House adopted the crest of the Rolleston Family Coat of Arms as  its symbol.
