Best Nanny Payroll Service in New Zealand

Hiring a nanny is one of the more personal decisions a family will make. You're not just filling a job vacancy. You're inviting someone into your home to look after the people you care about most. Finding the right person takes time and thought.

But once your nanny has started, there's a second job that a lot of parents don't see coming: payroll.

Between PAYE, KiwiSaver, annual leave, sick leave, public holidays and the eventual final pay, New Zealand employment law has a habit of getting complicated fast, especially if you've never employed anyone before.

Broadly, families end up choosing between three options:

• Letting your nanny agency handle payroll
• Using general payroll software
• Working with a specialist nanny payroll service

Each has its place. But the differences between them matter more than most people expect, both for your day-to-day experience and for staying compliant as an employer.

Option 1: Payroll Through a Nanny Agency

A lot of agencies will offer to handle payroll once they've placed your nanny, and on the surface that's convenient. One provider, one relationship, done.

The catch is that payroll is usually a side offering for an agency whose real business is recruitment. Once your nanny's actually working for you, ongoing payroll needs someone who lives and breathes employment legislation: leave calculations, public holiday entitlements, tax obligations, and whatever's changed in the law since last year. That's a different skill set to sourcing candidates, and it shows.

You're also often paying agency-level fees for what amounts to basic payroll processing, more than you'd pay for the payroll expertise on its own.

Option 2: Payroll Software

Platforms like Smartly, PayHero and Xero Payroll are genuinely good pieces of software, built for businesses of all shapes and sizes across NZ.

But that's exactly what they are: software. You're still the one responsible for:

• Setting your nanny up correctly in the system
• Understanding the relevant employment legislation
• Processing leave correctly, including the finer points of the Holidays Act
• Getting final pay calculations right
• Keeping across legislative changes as they happen
• Troubleshooting when something doesn't look right

If you've got payroll experience already, this can work fine. But for a family employing one nanny, it can feel a bit like being handed enterprise software and told to figure it out, because domestic employment has quirks that most general payroll tools simply weren't built around.

Option 3: A Specialist Nanny Payroll Service

This is where a dedicated provider looks quite different.

Rather than handing you a login and leaving you to become the payroll expert, a specialist service pairs a modern platform with real payroll people who understand domestic employment specifically. Not payroll in general, nanny payroll.

Instead of working out how to process something yourself, you can just ask someone who already knows.

That's a meaningfully different experience when you're dealing with a payday deadline and a question you weren't expecting.

Why the Specialist Knowledge Actually Matters

Paying a nanny isn't the same as running payroll for a retail team or an office. Families come up against questions like:

• How is holiday pay actually calculated?
• What are the annual leave entitlements after 12 months?
• Is my nanny eligible for sick leave yet?
• How do public holidays get paid when they fall on a normal working day?
• What's the difference between casual and permanent for payroll purposes?
• How do I calculate a final pay correctly?
• What are my KiwiSaver obligations as the employer?
• How does PAYE and IRD reporting actually work in my situation?
• What happens if we need to change the employment agreement?

None of these have a one-size-fits-all software answer. They come down to experience, and having a team that deals with nanny payroll every single day, rather than payroll in general, means the advice you get is actually relevant to your situation.

It's a Service, Not Just Software

The biggest difference, arguably, is that specialist nanny payroll is built around service first.

Technology still matters here: an online portal, digital timesheets, self-service access, automated processing. All of that makes life easier. But behind it is an actual team who already understands your setup.
