What is NZST in BST?
British Time is 11 hours behind
New Zealand Time is on UTC+12:00 and British Time is on UTC+1:00 right now. British Time is on daylight saving, so its clocks read BST. The gap changes during the year — see below.

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 – September 26, 2026British Time is 11 hours behind
- September 26, 2026 – October 25, 2026British Time is 12 hours behind
- October 25, 2026 – March 28, 2027British Time is 13 hours behind
- March 28, 2027 – April 3, 2027British Time is 12 hours behind
- April 3, 2027 – September 25, 2027British Time is 11 hours behind
- September 25, 2027 – onwardsBritish Time is 12 hours behind
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
New Zealand Time

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 (BST) 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.
