I need advice and recommendations where to go in South Island NZ for 7 days for a family of 5. We begin our journey in Auckland for 4 days and then travel to the South Island for 7 days. What is the best way to travel from Auckland to South Island? Initial plan is to go Queenstown for 3 days and then Wanaka for 4 days. We would love fishing in the Lake (winter?). Also I would greatly appreciate any recommendations on hotel or spa resort with hot springs and great views. Many thanks in anticipation!!
