Daylight saving 2026: When it ends, why we observe it and how to change the time on your phone

Enjoy your evening walks while you can – daylight saving will soon come to an end for another year, which means we all get an extra hour of sleep.

But when do the clocks switch over? Why do we observe daylight saving? And how do you change it on your phone?

Here’s what you need to know.

When does daylight saving end in New Zealand?

Daylight saving time ends every year at 3am on the first Sunday in April – which this year will be at 3am on Sunday 5 April.

Do the clocks go forward or back?

To quote the immortal Doc Brown, great scott! We’ve got to go back to the future.

That’s right: Clocks go back for the winter, from 3am to 2am.

That means you get an extra hour’s sleep-in and it won’t be as dark when you wake up in the morning – at least for a while.

It also means the sun will go down an hour earlier in the evening, so if you’ve got outside chores to complete, get them done faster.

Why do we have daylight saving time?

Because the Earth is on a tilt (of about 23 degrees, for those curious), we are exposed to more sun during summer and less during winter.

That means the days are longer during the warmer months and shorter in the colder months.

Daylight saving is intended to make the most of those long daylight hours. It means an extra hour of light on summer evenings.

How long have we been doing this?

New Zealand first observed daylight saving in 1927.

However, the dates that clocks went forward and back, and the amount of time they were changed, varied over the following years.

In 1941, daylight saving was extended year-round under emergency regulations to help save energy during World War II.

Five years later, daylight saving time (or summer time as it was then known) was adopted as standard time, effectively discontinuing daylight saving.

In 1975, daylight saving was introduced again.

It was extended to its current dates – from the last Sunday in September to the first Sunday in April – in 2007.

How do I change the time on my phone?

Most smartphones will adjust to time zones automatically.

Here’s how to check if your smartphone does that:

• Android: Go into the clock app, tap more and then go into settings. Then go into change date and time, select set time zone automatically and then select use location to set time zone.
• iPhone: Open settings, select general, to go date & time and make sure set automatically is turned on.
• Samsung: Open settings, go to general management, select date and time and then make sure automatic date and time is turned on. This should mean your phone will automatically reflect the time depending on where you are.

When will daylight saving time start again?

Clocks will go forward one hour at 2am on Sunday 27 September.

What if I’m working when the time changes?

The rules around getting paid for working during daylight saving time are set out in the Time Act 1974.

It says that if you’re working when clocks go back an hour, you are entitled to be paid for that extra hour.

For example, if your shift started at 10pm and finishes at 6am, you will have actually worked nine hours and must be paid for nine hours of work.

If you’re working on 27 September when the clocks go forward, you are still entitled to be paid for your normal hours. In this instance, a 10pm-6am shift will only mean seven hours of work, but you must be paid for eight.

I’ve changed the wall clock – what’s next?

Emergency officials say that daylight saving is a good time to check the batteries on your smoke alarm by pushing the test button to sound the alarm.

Check the alarm’s expiry date too – most last a maximum of 10 years – and give the cover a clean to avoid false alarms from dust buildup.
