My partner and I are planning a trip to NZ in March 2018 for 2 weeks. We are going to Airbnb most of our accommodation in advance and will stay two nights in each location and day trip out. I am planning on getting places with kitchens to reduce eating out costs. We are hiring a car and plan to spend 2-3 days in the North Idland before catching the ferry to the South Island and touring down for the rest of the time. We are planning a few pricey things (jet boat ride, guided day hike into Routeburn Track) but mostly site seeing. How much money would people recommend we take?
