We are driving from Greymouth 10th November. We are staying overnight at Franz Joseph then on to Wanaka for another night. We are booked in Te Anau for 2 nights where we intend to do a day trip to Milford Sound from. We then spend 3 nights in Queenstown before flying to Christchurch. Does anyone have any suggestions of places not to miss on this drive please? This is our first visit to NZ and are not sure what weather/temperatures to expect. Any advice would be most helpful.
