In reply to Brandon Copley:
www.freeclimb.co.nz has free topos for some of the sport, trad and bouldering in the north.
www.mojozone.co.nz has good forum for getting info.
Also I have a topo for the Airstrip (bouldering) at Waitomo, if you want it email me.
Cool, I'm really jealous especially if you go south and visit Castle Hill!
