New Zealand's 2 main islands, North Island and South Island, both lie in the same time zone. The Chatham Islands, located about 860 kilometers (534 miles) east of Christchurch, have a separate time zone, which is 45 minutes ahead of mainland New Zealand.
Tokelau, an archipelago in the Pacific and a dependency of New Zealand, brings the total to 3 time zones.
Because Tokelau does not use Daylight Saving Time (DST), there are only 2 corresponding DST time zones.

New Zealand was one of the 1st countries in the world to officially adopt a nationally observed standard time. New Zealand Mean Time, adopted on November 2, 1868, was 11 hours and 30 minutes ahead of Greenwich Mean Time (GMT).
In 1941, during World War II, clocks were set forward 30 minutes, increasing New Zealand's offset from GMT to 12 hours. The time change was made permanent by the Standard Time Act 1945.
