Replying to Spending a Summer in New Zeland

Wondering if anyone has experience with this. I want to head to NZ with a few buddies, and basically work at the slopes, whether it is teaching, lifts, or anything I could do. If anyone has done this, has a suggestion on what Mountain, what the costs are going to be (will a mountain job provide adequate money for me to live) and any general suggestions. I plan on being there from like mid-may or early june to Early-mid august. Let me know, thanks.
