Probably not as will be mostly rock in the steeper section down low...it does get climbed when out of condition but needs a few scary wire placements i nthe lovely NZ rock and a confident leader. I'd just run up the standard NW Ridge in Feb. I have climbed Zurbriggen's Ridge on Cook in mid March which was quite good conditions, no new snow avalanche risks and the old snow base was nice and firm. Most people tend to solo the 1000 metres or so of constant 50 degree snow until you hit the flat spot on the ridge to the right and then follow the crest for about 4 - 5 pitches of nice mixed climbing over rocks and snow to reach the base of the Summit Rocks (this is where the standard Linda Glacier route comes in from the right as well so the usual fast decsent route). Summit Rocks have wire cables for speedy belays/raps every 25m or so and are usually 4 pitches in total. Once you see the summit it is about another hour or so to the Chandeleir and the crest of the summit ridge. Airy balancing act walk for 30 - 40 metres will see you just below the final few metres of Aoraki's summit. Try not to stand on top of the last few metres as you want as much good juju for the descent!!!
