if it where I think it is, I visited it in 2004 on the way to The Routeburn. The quake was Feb 2011. I think it unrepairable so will be torn down the rest of the way.
I may be wrong. Wonder if part of the cathedral design is a rubber stamp and CXV 115 is somewhere else? The origins of Christchurch Cathedral date back to the plans of the Canterbury Association who aimed to build a city around a central cathedral and college in the Canterbury Region based on the English model of Christ Church, Oxford.
