WORST WINTER?!?!?!?!? Yo uhave got to be kidding. THis has been their best winter in over 15 years. So, I don't know where you went, but it sure wasn't new zealand.
Plus, in New Zealand, if you get hurt, all the costs are covered under ACC. Pretty much like Canada.
If you come to NZ, you will want to stay in Wanaka, and hit up Snowpark with all the best pros in the world, and then Trebble Cone. Both of them are sweet as. Cadrona is also cool, but not nearly as fun as Treble Cone and Snowpark.
