It has been several years since we did this trip. We rented a 19ft right hand drive class B. I had lived in Japan so I was used to driving in the left lane. My only problem was turning on the windshield wipers when I meant to use the turn signals. All kidding aside, it is a wonderful place to RV..aka caravan. We started on the south island and worked our way north. Taking your time is important. The people are friendly and helpful and the fishing is out of this world.
