The history of DST in New Zealand started more than 20 years earlier. In 1895, the scientist George Vernon Hudson presented a paper to the Wellington Philosophical Society advocating seasonal time adjustments. The society members ridiculed his idea. However, in 1909, the parliamentarian Thomas Sidey proposed to move the clocks 1 hour forward in New Zealand’s summer period to allow for an extra hour of daylight in the evenings.
The Summer Time Act 1927, set the clocks forward 1 hour, but the measure was unpopular. The Summer Time Act 1928 reduced the time change to 30-minutes instead. After the Summer Time Act 1929 went into effect, the DST period lasted from the 2nd Sunday in October to the 3rd Sunday in March. In 1933, it was extended to run from the 1st Sunday in September to the last Sunday of April.
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.
New Zealand's current DST schedule was established by the Time Act 1974. The measure proved so popular that the start and end dates of the DST period were extended several times. Following the Daylight Time Order 1990, DST ran from the 1st Sunday in October to the 3rd Sunday in March.
In 2007, New Zealand’s Minister of Internal Affairs, Rick Barker, announced that the DST schedule was to be extended further. The decision was made after a survey and petition found that people favored an extended DST period. DST in New Zealand is today observed from the last Sunday in September to the 1st Sunday in April.
