Because of the consistent warmth and long daylight hours, New Zealand in December is a delightful time to explore coastal areas, lakes, and picturesque hiking trails. To make the most of it, dive into some of the best things to do in New Zealand this month:
With warm summer air and calm seas, December is an excellent time to explore the network of waterways, bush-covered hills, and peaceful bays in the Marlborough Sounds. You can rent a kayak and go it alone, or take a scenic boat tour that departs from Picton, which provides the opportunity to spot dolphins and visit remote beaches.
Towering above Queenstown, the Ben Lomond Track offers panoramic vistas over Lake Wakatipu and the Remarkables mountain range. The summit is about 5,700 feet (1,748 meters) above sea level, which means the full-day trek is challenging but rewarding; start early to avoid the midday heat. Wildflowers dot the landscape in December, and the extended daylight hours allow for a more relaxed pace.
With its subtropical climate, the Bay of Islands is one of the best places to soak up the summer sun. Swim, sail, and snorkel around the 140 islands, or simply relax on white-sand beaches. Boat tours offer dolphin-watching and access to secluded spots like Urupukapuka Island.

Castle Hill, located in Canterbury, is known for its dramatic limestone formations scattered across high-country grasslands. The area is a favorite with rock climbers, photographers, and hikers. In December, it's cooler than in lowland regions, making it a comfortable stop for walking, picnicking, or enjoying the majesty of the landscape.
The Mackenzie Basin delivers wide-open landscapes, turquoise lakes, and unforgettable views of the Southern Alps. The lupins that bloom around the lake in early summer add extra color to an already striking landscape. Take a road trip between Lake Tekapo, Twizel, and Mount Cook Village, stopping at scenic lookouts, or book a short glacier flight.
The summer weather in New Zealand in December creates a platform for outdoor events focused on music, culture, and community spirit, all with a festive energy.
