Whether you have a team of 5 or 500, payroll isn’t something to take lightly. It’s not just about making sure everyone gets paid on time—it’s about getting every detail right, staying compliant with employment legislation, and protecting your business from costly mistakes.
At Red Office, we work with businesses across New Zealand, and we see it all—from savvy in-house teams to busy business owners juggling payroll on top of everything else. If you’re managing payroll yourself or have an internal team doing it, here are a few key things worth considering.
1. Compliance isn't optional
New Zealand’s payroll landscape is complex and constantly evolving. Between the Holidays Act, Minimum Wage updates, and KiwiSaver obligations, there’s a lot to stay on top of. Misinterpreting legislation (or missing changes altogether) can lead to underpayments, overpayments, and penalties from the IRD or MBIE.
Common compliance challenges include:
- Miscalculating annual leave under the Holidays Act
- Incorrectly applying public holiday entitlements
- Failing to keep compliant payroll records
- Not understanding employee classifications (e.g. casual vs part-time)
Even small errors can add up—especially if they go unnoticed for months or years.
2. Don't rely on software alone
Yes, payroll software is a lifesaver. It automates the process, calculates deductions, and files directly with the IRD. But it’s only as good as the data you feed into it.
If leave is entered incorrectly, hours are misclassified, or employment agreements aren’t reflected accurately in the system, the software will still process it—just wrong.
Tip: Regularly audit your system inputs, check that settings match your employees’ current agreements, and make sure whoever is managing payroll understands the “why” behind each rule or calculation.
3. Do you have backup and oversight?
What happens if your payroll person is away or suddenly leaves? Can someone else step in confidently? Is there oversight to catch mistakes or review approvals?
Payroll often gets handed to one person who becomes the “go-to” – but without cross-training, clear documentation, or checks and balances, that creates a risk. Internal fraud, accidental overpayments, or missed deadlines can and do happen.
A few questions to ask yourself:
- Is there always cover for payroll if someone’s away?
- Do we have a monthly checklist or internal audit process?
- Who reviews payroll before it’s finalised?

4. The hidden time cost of DIY payroll
Time spent fixing leave balances, chasing timesheets, or navigating legislation is time not spent growing your business or supporting your team. While in-house payroll may seem more cost-effective at first, it can come with hidden costs—especially if things go wrong.
Outsourcing part (or all) of your payroll doesn’t mean losing control. It’s about gaining peace of mind, saving time, and knowing experts are keeping you compliant behind the scenes.
