In reply to LittleJoe: hey, I have rock deluxe, most of the independent crag guides for the South Island and a few of the Alpine Club guides too. they are in a box at a mates in Christchurch, If you don't want to buy then there could be an option to 'borrow' them for your trip.
I'm back in the UK so they aren't getting used.
Off the top of my head, places i'd recommend would be Chinamans Bluff (amazing mixed routes, multi pitch sport and trad). Wye Creek for more sport. Go further past Hospital Flats for more sport (literally hundreds of routes in the Wanaka area).
You can hire bouldering pads in Christchurch if you're thinking of going to Castle Hill (highly recommend)
PM me for details about the guide books etc
