When the difference changes
Greenwich Mean Time and New Zealand 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 – September 26, 2026New Zealand Time is 12 hours ahead
- September 26, 2026 – April 3, 2027New Zealand Time is 13 hours ahead
- April 3, 2027 – September 25, 2027New Zealand Time is 12 hours ahead
- September 25, 2027 – onwardsNew Zealand Time is 13 hours ahead
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
Greenwich Mean Time
Greenwich Mean Time stays on GMT all year, so its offset from UTC never moves.
New Zealand Time
Clocks go forward one hour at 2am local time, becoming NZDT.

Scheduling between the two
There is no overlap between a nine-to-six working day in Greenwich and one in Auckland — the gap is too wide. A call has to sit early or late for one side. Early morning in Greenwich is the usual compromise, since that is late afternoon or evening in Auckland.
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.
