New Zealand has a beautiful coast and plenty of wind most times of the year. In addition to great kiteboarding and windsurfing, it offers countless other outdoor activities like skydiving, ziplining, or rafting to make it worth the trip. Generally, you'll have a chance of wind any time of year, but September to December are the windiest months. If you come during New Zealand's winter, you will need a full wetsuit.
New Zealand offers not just premium coastal kitesurfing but also amazing lake locations with NW wind, particularly on South Island. Lake Coleridge is rather cold, and Lake Clearwater is shallower and warmer, which is perfect for beginner kitesurfers. Wanaka and Wakatipu are also famous lakes, although they can be gusty. Lake Aviemore gets summer thermal winds.
East Coast of the South Island has good east winds. Christchurch area has 15-20 knots during summer. New Brighton Beach and Waikuku beach have great kiting. Ashley river mouth lagoon is good to learn to kitesurf. In the north, Golden Bay has sand flats, vast beaches, and a huge shallow lagoon.
