NZST to AEST

About New Zealand Time

New Zealand is UTC+12 as NZST and UTC+13 as NZDT, which makes it the first populated place to reach any given date. Its clock changes in late September and early April — the opposite half of the year to the northern zones on this site, so a gap to Europe or North America can swing by two hours rather than one.

Cities on this clock: Auckland, Wellington.

About Australian Eastern Time

Sydney, Melbourne and Canberra run at UTC+10 as AEST and UTC+11 as AEDT, changing on the first Sunday in October and the first Sunday in April. Queensland does not change at all, so Brisbane matches Sydney for about half the year and sits an hour behind it for the rest — on the same "Eastern" label.

How the difference is worked out

The gap between New Zealand Time and Australian Eastern Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 2 hours and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.

With both zones on their own standard time — daylight saving not in force anywhere — Australian Eastern Time is 2 hours behind New Zealand Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.

Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids Pacific/Auckland and Australia/Sydney. Nothing is looked up on a server and nothing about your visit is recorded.
