When the difference changes
New Zealand Time and British 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 – March 28, 2027British Time is 13 hours behind
- March 28, 2027 – April 4, 2027British Time is 12 hours behind
- April 4, 2027 – September 26, 2027British Time is 11 hours behind
- September 26, 2027 – October 31, 2027British Time is 12 hours behind
- October 31, 2027 – onwardsBritish 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.
British Time
Clocks go forward one hour — 1:00 am becomes 2:00 am local time, and the zone is on BST after that.

Scheduling between the two
There is no overlap between a nine-to-six working day in Auckland and one in London — 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 London.
A note on BST: it can also mean Bangladesh Standard Time (UTC+6). This page means British Summer Time.
British Time (GMT) is used in the whole United Kingdom. In winter the UK is on GMT; from late March to late October it is on BST, an hour ahead.
