Yes I know the South Island is on top of the North Island as it appears below, but we fly into Christchurch and travel the South Island, crossing to the North Island by ferry from Picton to Wellington, and finish and fly out of Auckland.  The dots on the route maps represent night stops, check the Itinerary tab for the exact details. Given the November 2016 South Island earthquake the only road affected maybe the Kaikoura to Blenheim coast road.  We hope that this portion will be open again by 2018.
