We just came back from 4 weeks travelling NZ in a campervan/motorhome. We flew into Auckland and flew out of Christchurch. We went in May. Absolutely loved it, kids had a ball. The caravan parks were clean and all had great playgrounds for the kids.

We loved it so much that we can't wait to do it again. We went through Apollo for our camper and got a 6 bedder. We found that we could fit all 3 kids to sleep in the bed above the cabin and then we would sleep in the rear and there was no need to open up the third bed which is handy as you need all the space you can get! Not a lot of room for storage - during the day our bags were in the top bed and we would have to take them down at night. Never used the shower in the camper, too crowded and the shower facilities at the parks were all really good. It did get cold at night and the heaters in the campervans cut out once the outside temp reached a certain degree (for safety reasons apparently which was a bit stupid as that's when you needed it!). So halfway along our journey we stopped at one of the depots and picked up an extra doona.

Hmm can't think of anything else atm but if you have any specific questions I might be able to answer them for you.
