While 10 days is not enough to see the entire country, it is sufficient to experience the highlights of one island or a very fast-paced "top hits" tour of both. In 2026, a popular 10-day South Island itinerary includes Christchurch, Lake Tekapo, Mount Cook, and the adventure hub of Queenstown, including a day trip to Milford Sound. If you attempt both islands, you will spend a significant portion of your time in transit, typically requiring at least one domestic flight (e.g., Rotorua to Christchurch) to bridge the gap. For a more meaningful experience, many experts recommend dedicating the full 10 days to the South Island’s dramatic alpine scenery or the North Island’s geothermal wonders and cultural sites. To maximize your time, consider renting a campervan, which allows for flexible overnighting in the country's breathtaking "freedom camping" zones and national parks.
