[3] New Zealand's associated states – the Cook Islands and Niue – and the dependent territory of Tokelau use several different time zones at their own discretion.
On 2 November 1868, New Zealand officially adopted a standard time to be observed nationally, and was the first country to do so, about fifteen years before any other.
[13] Starting in 1909, a member of Parliament, Sir Thomas Kay Sidey annually put forward a bill to advance the clocks an hour from September to the following March and the Summer Time Act 1927 succeeded.
Public attitudes towards NZDT (New Zealand Daylight Time) and its effects on work, recreation and particular groups of people in society were surveyed.
[15] The survey also concluded that opinion on the topic differed little between sexes, and that support for NZDT was generally higher in urban centres.
Daylight saving was famously opposed in the small Northland dairy farming community of Ararua,[16] which refused to adjust its clocks for some years.
This results in the oddity that the Amundsen–Scott South Pole Station sets its clocks an hour further ahead during the southern summer, when the sun is constantly above the horizon, than in the southern winter, when the sun is constantly below the horizon.
However, the arrangement presumably makes real time communications with New Zealand more practical, particularly in dealing with offices.
The other countries in the Realm of New Zealand – Cook Islands, Niue, and Tokelau – do not maintain DST.
[19] There are two associated states of New Zealand in the Pacific Ocean, both on the other side of the International Date Line: The New Zealand dependency of Tokelau is in the UTC+13:00 time zone[20] or Military M' (Mike Prime)[1] and does not observe daylight saving time.
