The amount of time to spend in New Zealand to see the major highlights depends on your interests and the activities you wish to experience. Ideally, a trip of at least two to three weeks would allow you to cover the major highlights of both the North and South Islands. However, if you have limited time, it’s still possible to see some of the highlights in a shorter period. Focus on specific regions or cities that align with your interests, such as exploring the geothermal wonders of Rotorua or hiking in the Southern Alps around Queenstown. Ultimately, the longer you can spend in New Zealand, the more you can immerse yourself in its stunning landscapes, diverse culture, and unique experiences.
