Been 14 years but I was there with a tour group in 2004. We rented Maui Class C's, which are similar to Sprinter based Class C's in the US. Some had auto trannys, others manual. Manual is a real challenge as ours were 6 speed and if you missed 3rd and hit 5th the engine died and you had to go to park to restart! Driving on the wrong side of the road, and in roundabouts, added to the challenge of left handed shifting, but we all survived. There was also a large number of van type RV's labeled as "Wicked Campers" that had racy graphics and were mostly occupied by young folks. Campgrounds were plentiful and good. Not sure what advance reservations may be required as the tour made them. Met lots of interesting Kiwi's in the CG's, and had great sport asking them to show us the Southern Cross constellation as most could not.
Be aware that a Kiwi interstate highway is only two lanes, and most bridges are one way. One day we encountered 57 one lane bridges on the drive. The longer ones have pullouts at one or more points.
It was a memorable, and fun trip. Our Fall is their Spring. All the baby lambs on the green pastures are real eye candy.
