We visited Snowplanet today. It is located in Silverdale, Auckland. It was packed full of kids and families having a fun time. I must say snow is not my thing, but it was lovely to take our kids there even though they are too small still.
You can rent boots, jackets and mittens at Snowplanet. There are also a Restaurant there where you can have something to eat.
Kids under 2 are free. For 1 hour and all four of us it was $160, for Winter Wonderland. My husband went down the sleigh with our toddler once. It is a bit pricey for what you get, but it was nice to explore the things in Auckland.
