Camping
There are numerous places to camp in New Zealand. In this section I'll be talking mostly about places that you can drive to. If you're interested in walking to a camping area check out the tramping section of this site.
Coromandel Peninsula
There are some great DOC campsites up near the top of the peninsula faintail bay, stoney bay, port jackson and waikawau bay are all great places for a camping trip although they can get quite busy around New Years and Easter.
There are numerous free campsites at road ends around the Kaimanawas.
