The Proscenium arch was also widened by 1.5m and the stage and fly tower were made wider and deeper.

The 1908 auditorium and foyer sustained considerable damage during the February 2011 Christchurch earthquake and the June aftershock.

At a cost of $40 million the Theatre was completely restored and brought up to current building code requirements.

[8] All of the significant architectural elements were rescued and restored by skilled craftsmen; including a completely rebuilt auditorium dome made from carbon fibre using the original 1908 painted mural by Studio Carolina Izzo.
