In our time zone, two pieces of legislation govern daylight saving dates and the rules regarding what happens if you are working when the clocks change.
- Time Act
- NZ Daylight Time Order
So what happens you are working when the clocks change?
Working when daylight saving begins or ends
Early Sunday morning was chosen for the changeover because fewer people were working at that time, and this reduced the impact on workers and employers.
If you work when daylight saving begins, and the clocks go forward, you actually work an hour less, but you are entitled to payment for your normal hours. For example, if you were meant to work from midnight to 8 a.m., you will only work 7 hours, but you are entitled to be paid for 8 hours of work.
If you work when daylight saving ends and clocks go back an hour, you are entitled to any extra hours that you work. So, if you were meant to work from midnight to 8 a.m. but actually work 9 hours, you will be paid for 9 hours of work.
