Stayed at the Pine Beach Campground - fantastic area for families and children.
Huge sandshelf in the lake means warm knee high water for about 50 metres, before a relatively steep drop off to about 30m deep.
Only complaints would be the need for cold water showers rather than just the $2 paid hot ones; and the surrounding landscape needs some years to recover from the pine forest removal as it's a bit barren at present.
Close to drive to Tane Mahuta and walks in the Waipoua forest mean there's heaps to do - at least in the connecting to nature kind of way.
