Fiordland! If you want climbing in NZ that is big and good fiordland fits that bill. You can base yourself at Homer hut along the Milford road where there is a huge array of big mulipitch granite walls on good rock in a great setting. The Nzac guidebooks are good if you know your going to spend time a lot of time in a certain area. Then queenstown and Wanaka have lots of shist sport climbing ranging from some single pitch to some great mulitpitch in some areas. They all have local guidebooks. The South Island Rock is ok but nothing special.
