Discover the best of New Zealand in 2 weeks! For this itinerary, you'll need to fly into Queenstown first. Rent a campervan or car from there and explore the South Island first. Then drop the vehicle in Queenstown and fly to Auckland. Rent another vehicle to explore the best of the North Island. We highly recommend doing it this way as it will eliminate lots of hours driving so you can optimize your time exploring!
Note that some days are populated with multiple options/hikes in one area because based on your preferences or activity level, you can pick and choose.
