When the difference changes
New Zealand Time and Greenwich Mean Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – April 4, 2027Greenwich Mean Time is 13 hours behind
- April 4, 2027 – September 26, 2027Greenwich Mean Time is 12 hours behind
- September 26, 2027 – onwardsGreenwich Mean Time is 13 hours behind
Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.
Daylight saving
New Zealand Time
Clocks go back one hour — 3:00 am becomes 2:00 am local time, and the zone is on NZST after that.
Greenwich Mean Time
Greenwich Mean Time stays on GMT all year, so its offset from UTC never moves.

Scheduling between the two
There is no overlap between a nine-to-six working day in Auckland and one in Greenwich — the gap is too wide. A call has to sit early or late for one side. Early morning in Auckland is the usual compromise, since that is late afternoon or evening in Greenwich.
Greenwich Mean Time (GMT) is used in as a fixed UTC+0 offset. Note that the UK itself leaves GMT every summer — see British Time below.
