I am in Christchurch as a base for dumping the rental car and taking the TranzAlpine to Greymouth...
It appears to be a bit of a shit hole (largely as a result of the mahoosive earthquake)...
The six 'MUST DO' (still standing) attractions are: -
1) A tram ride
2) A gondola ride
3) A wildlife reserve
4) A whale watching cruise
5) The International Antarctic Centre
6) Punting on the River Avon

Given that rain is forecast for tomoz I might stay in bed. Or drop the rental car (a KIA Sportage, I love it) off and go back to bed...
