For those interested in another look at what has been wrought in Christchurch: Land Information New Zealand has released aerial imagery (links here) of Christchurch post-quake.
The part I went looking for first was Coker's Hotel on Manchester Street (dating from 1879). It's a backpackers now, and that's where I stayed in 2007 for a couple of nights.
Now, it is in a sad state, going by the aerial. It was already closed after the September 2010 quake.
