Thank you billhilly. I will look into the DOC campgrounds.
Was the auto-insurance on your credit card insufficient? I checked mine with a couple rental companies and they seemed to say it was okay. This has worked for me in other countries. Thanks
The DOC camps were an absolute revelation. Really magnificent locations, and pretty low fees. No facility's much, but if you're self contained in your camper you are good to go. We alternated between them, and full camp grounds so we could shower/wash.
Don't know anything about insurance on your credit card, maybe a US thing. Interesting it has worked in other countries. We went with Maui, second tier (4-5 yr old?).
Also, that is pretty much the same route we are planning. How many days did you take? Did you feel rushed? We have 10 days.
Thanks.
We flew into Christchurch (from Wellington) and spent 13 days on the road. Rushed, well we drove all except two of the days. We did a total of 2500k's. Depends how many k's you are planning on trying to do I guess. MUCH different driving conditions than the US. Narrow windy two way roads, will mean a much lower average travel speed than you are used to. The Arthurs Pass, West Coast, Queenstown, Milford Sound, Mt Cook loop certainly takes in some pretty spectacular scenery. I guess the bottom line is with ten days on the ground you will have full days regardless!

Let me know if you need any more info.
PS. I uploaded some photo's to an album on here, but never made the trip report! If you have a look in the albums (under my name) you'll see some pictures of the trip. Scroll over them gives you a brief description.
