History
This time zone was used as standard time in New Zealand and Norfolk Island.
On November 2, 1868, New Zealand officially adopted a standard time to be observed nationally, and was perhaps the first country to do so. It was based on the longitude 172° 30' East of Greenwich, that was 11 hours 30 minutes ahead of Greenwich Mean Time. This standard was known as New Zealand Mean Time (NZMT).[2] New Zealand changed from NZMT to New Zealand Standard Time (NZST) as UTC+12:00 in 1946 (after using this time zone as a daylight saving time since 1928, including permanent daylight saving from 1941).[3] It was officially changed to 12 hours in advance of UTC in 1946.[4]
Norfolk Island's standard time (NFT) was on UTC+11:30 until 4 October 2015, when it was changed to UTC+11:00.[1]
