Climb an Auckland mountain
While we don't necessarily have any mountains, a handful of extinct volcanoes are littered throughout Auckland city. Admission is free and if the kids have a lot of energy, you could try knocking off a few different climbs in one day. Standouts include Mount Eden, One Tree Hill, North Head, Mount Wellington and Mount Albert.
Snowplanet
Pack in your beanies, warm jackets and head up to Snowplanet near Silverdale, only 30 minutes north of Auckland city. Open weekdays from 10am and weekends from 9am, the indoor ski slope offers plenty of skiing, snowboarding or snow tubing fun if you can't head away to a proper mountain slope this winter.
