The largest ski resort in New Zealand is Cardrona, near Wanaka, in the South Island. The weather there is much more reliable than in the North Island, in places such as Mount Ruapehu.
In my opinion Cardrona is the best, especially if you are just starting skiing or Snowboarding.
The best ski resort for beginner skiers in New Zealand is Cardrona which is located in Mt. Dobson.
It is the largest indoor ski resort but it is not nearly as big as most outdoor ski resorts.
