We will be in NZ from Sep 30 - Oct 15. Flying into Queenstown, and plan to head to the North Island on the 7th. I originally was planning to fly from Christchurch to Rotorura, then take the coach to Auckland via the Waitomo caves. Want to do a one day tour up to the Bay of Islands from Auckland. Am wondering if we should consider taking the train from Christchurch to Picton, then the ferry to Wellington for a couple of days instead? We are active retirees--
Thanks for any input.
