The best time to visit New Zealand is during the months from December to February are New Zealand's summer months, unlike other countries where it's vice versa. Relaxing at the beach, hiking and other adventure activities are best enjoyed during these months. There are also a lot of concerts and festivals that take place during this period, so you can make the most of your journey. The rest of the year it gets really cold and a lot of the natural landscape is inaccessible due to heavy snow.
