Hi - we arrive in Chch late on the 9/4 spend 2 nights then want to spend the next 9 nights seeing as much as we can in a rental car. General advice seems to head straight to the west coast via Arthurs Pass,south to Haast, inland to Wannaka and Queenstown. Finishing off back in Chch. Where should we stop and spend nights and for how long. We are in our 40s so no children to consider. Should we try and cram Dunedin in as well?
