TempusSleepovers are the single most commonly mis-paid item in New Zealand care payroll. The rules are not especially complicated — but they interact with minimum wage and leave in ways that most payroll setups rarely account for.
If you run a residential disability service, a rest home or a supported living provider, you already know that overnight cover is where payroll gets hard. What is less obvious is that the errors rarely show up as an obvious wrong number. They show up as a slow drift that only becomes visible when someone leaves, or when a balance is finally checked properly. That timing is the awkward part: by the point a final pay makes the problem visible, it has usually been running for a while, and rarely for just one person. Knowing where the drift starts is most of the work.
The Starting Point: Sleepover Time Is Work
New Zealand settled this a long time ago. Time an employee spends sleeping over at a workplace, required to be there and available to respond, is work time. It is not a standby arrangement sitting outside the employment relationship, and it cannot be treated as unpaid time with a small allowance attached.
In practice that means two things. The sleepover hours count when you test whether someone has been paid at least the minimum wage, and they count as hours worked for the purposes that flow from that.
Where It Goes Wrong: The Minimum Wage Test
The most common error is paying a flat sleepover allowance and stopping there. An allowance on its own is fine — plenty of agreements use one — but you still have to check that total pay divided by total hours worked clears the minimum wage for the period.
Take a support worker who does a nine-hour sleepover and is paid a flat allowance for it, on top of their daytime working hours. If you divide their total pay for the pay period by their total hours including the sleepover, and the result sits below the minimum wage, you owe a top-up. That top-up is not optional and it is not something your payroll system will necessarily work out for you.
A sleepover allowance is a payment method. It is not a substitute for the minimum wage calculation.
Disturbed Nights
If the employee is woken and has to work — a call-out, a medication event, a resident needing support — that active time is working time in the ordinary sense and is paid accordingly. Most collective and individual agreements in the sector deal with this specifically, and the rate for disturbed time is often different from both the sleepover allowance and the ordinary daytime rate.
The practical problem is capture, not calculation. If disturbed time is recorded on a paper sheet in a house and typed up later — or worse, remembered — it will be wrong sometimes. Get it recorded at the point it happens.
The Part Almost Everyone Misses: Leave
Here is where sleepovers can quietly become expensive. Under the Holidays Act, annual holidays are paid at the greater of ordinary weekly pay and average weekly earnings. Average weekly earnings is based on gross earnings over the previous twelve months — and sleepover payments and disturbed-night payments are part of gross earnings.
So if your system is computing leave from a base hourly rate and treating sleepover payments as something separate that sits outside the calculation, every holiday that person takes is underpaid. Multiply that by a workforce doing regular overnights, across several years, and you have a remediation project.
Final pay works the same way, because the annual holiday component of it is calculated on the same weekly basis.
Alternative holidays are different, and this is where the error usually creeps in. An alternative holiday is a days entitlement, not a weeks one, so it is paid using relevant daily pay — or average daily pay where relevant daily pay cannot reasonably be determined. Sick leave and bereavement leave work on that same daily basis. If a sleepover has inflated someone’s weekly earnings, do not assume the same uplift flows through to these. The unit is different, so the calculation is different.
For care providers this is worth watching closely now, rather than waiting until the new Employment Leave Act rules apply in 2028, because the new framework draws a hard line between standard hours, additional hours and casual hours — and working patterns in this sector move between all three constantly. How your sleepovers are classified under that framework will matter.
A Five-Minute Self-Check
If any of those make you uncomfortable, the issue is almost certainly systemic rather than a one-off.
Why This Matters
Care providers are, in our experience, among the most conscientious employers in the country. The errors we find in this sector are almost never anyone cutting corners. They are configuration decisions made years ago by someone who did not know how sleepover payments would flow into a leave calculation, and which have quietly compounded ever since.
That is a fixable problem. It is just not one that fixes itself.
