New Zealand 2007 Daylight Saving Changes

Updated 19th September 2007

New Zealand 2007 Daylight Saving Changes In April 2007 the New Zealand Government announced an update to the Time Act of 1974. This update changes the dates of both the start and end of daylight saving time (DST). When this law goes into effect in 2007, daylight savings time will start one week earlier (2:00 A.M. on the 30th September 2007) and will end two weeks later (3:00 A.M. on 6th April 2008) than past years.

Unless certain updates are applied to software, the time zone settings for a computer's system clock and any calendar and scheduling applications may be incorrect during the three week transition period.

Updates are available for a number of Microsoft® products to include the new daylight saving times. Information on these product updates appears below. This web site is updated regularly as updates become available.
