Walked in and climbed it a couple of times by NW and SW ridges. Both times in November. Up FR and over quarterdeck each time on the way in. Stayed at Colin Todd for NW (up/down Ramp) and camped at base of SW for that trip. Exited by Bevan col for NW and back via FR for SW.
Definitely take stake and screw each. I'd take two screws each.
We pitched sections of the ridge above the ramp on the first trip because of blue ice. Two years later in November I plunged down the same section practically with my hands in my pockets.
NZ climbing is about preparing for the worst conditions and enjoying it when they aren't.
Get fit - vertical gain is what it's all about and is something that most Aussies don't get access to.
