We spent a few weeks driving a car around NZ a couple years ago. As others mentioned, the roads are pretty narrow, but the RV's are also small, so it's a challenge, but doable. Outside the major cities, it's a very rural,country lIke setting. I did not check any of the RV parks in NZ like I normally do on our travels. We've been to AU a couple times and found the RV parks to be very nice and in great locations. Many city/town operated parks. Maybe the same in NZ ? Good luck and have fun !
