Hey Sali-g,
We found somewhere to rent in both Auckland and Christchurch without any dramas at all. In fact, it took us just two days to find somewhere to live for 8 people (in Auckland), even though they knew we would only be there for a while. We even had a table-tennis table in the garage :icon_eek: icon_exclaim.gif !
As for anything special to recommend - there are too many things!! Nights out in Aucks probably centre around the Viaduct Basin, or for a more chilled atmosphere try Parnell and
Ponsonby, where I lived for a while. Also, Queenstown is a bit of a party town, although you will pay more to drink there than anywhere else...
As for stuff to see and do in general in NZ, I would recommend the Coromandel Peninsula as my all-time favourite spot in the whole of NZ. Awesome, dude.
If there is anything else I can help you with, just ask :icon_biggrin:
Dan-ish :icon_razz: (but you can call me Dan)
