By 1913 the roll at Canterbury College had increased to 354 students in total. Demands on space for teaching were matched by demands for administration as the College became an increasingly complex institution. It is useful to remember that administration for the Board and the Registrar meant not only managing the College but also the Public Library, the Girls' and Boys' High Schools, the School of Art and the Museum.
A separate Registry building was completed in 1916, having been designed by Collins and Harman at a cost of £2,944. Built on corner of Worcester and Montreal Streets at some distance from rest of College, the Registry was a relatively plain building, which begins to hint that the reign of Gothic Revival was coming to an end. Professor of Classics Hugh Stewart commented of the building in 1923 that “… it need only be said that the College is fortunate in its detachment.”
