An introduction to becoming an employer in New Zealand

First, the good bit

Hiring your first employee is a milestone. It means your business has grown beyond what you can do alone, and that's worth acknowledging before we get into the rest.

The rest is admittedly less exciting. Employing people in New Zealand comes with a set of obligations: some to the employee, some to Inland Revenue, some to employment law and other legislation requirements more broadly. None of them are individually complicated, but together they can feel like a lot when you're new to it.

The good news: you don't need to become a payroll or employment expert. You need a working understanding of what applies to you, the right systems to handle the mechanics, and the judgement to know when to ask for help. This course is here to give you the first two. The third you already have - you wouldn't be reading this otherwise.

What changes when you hire

Many small NZ businesses have operated as sole traders or worked with contractors for years before hiring their first employee. On the surface, it feels like a small addition: one more person, one more set of hands.

Legally, it's a bigger shift. The moment you have an employee, you're operating under a body of law that didn't apply before. You'll be deducting tax on someone else's behalf, you'll be tracking leave entitlements, you'll be obliged to act in good faith, and you'll be expected to keep records that hold up to scrutiny.

You don't need to read every Act cover to cover. You do need to know they exist, so you know where to look when a question comes up.

Worth knowing The most common mistake new employers make is finding out about an obligation only after something has gone wrong.

The legislation that applies to you

Once you have employees, the following pieces of legislation become directly relevant. We'll cover the practical implications throughout the course — this is just the landscape.

Employment Relations Act 2000 Governs the employment relationship itself - good faith obligations, employment agreements, personal grievances, and the rights of both parties. Read more at employment.govt.nz.

Holidays Act 2003 Covers annual leave, public holidays, sick leave, and bereavement leave. The incoming Employment Leave Bill will update key provisions.

Minimum Wage Act 1983 Sets the legal floor for what you can pay any employee, regardless of what's in their agreement. Current rates are at employment.govt.nz/pay-and-hours.

Wages Protection Act 1983 Governs what deductions you can make from an employee's pay, and what is off-limits.

Health and Safety at Work Act 2015 Requires you to provide and maintain a safe working environment. Applies to every workplace, regardless of size or industry. WorkSafe's guidance is a sensible starting point.

KiwiSaver Act 2006 Sets out your obligations around enrolling employees in KiwiSaver and making employer contributions.

Income Tax Act 2007 Requires you to deduct PAYE (Pay As You Earn) from each employee's wages and pay it to Inland Revenue on their behalf, as well as other tax requirements. 

Privacy Act 2020 Governs how you collect, store, use, and share personal information about your employees - from IRD numbers to medical certificates. The Office of the Privacy Commissioner has practical guidance for employers.

What happens if it goes wrong

Most employers who get things wrong didn't mean to. They missed a deadline, miscalculated a leave entitlement, didn't realise an obligation applied to them. The system isn't designed to punish employers acting in good faith, and the bar for actually being penalised is higher than people often assume.

That said, the consequences for getting things wrong are real. Depending on the breach, they can include IRD penalties and interest, backpay orders, fines from labour inspectors, and compensation awarded to employees through the Employment Relations Authority.

In serious cases, criminal liability now applies. From March 2025, deliberately withholding wages or entitlements is a criminal offence under the Crimes (Theft by Employer) Amendment Act 2025. That law is aimed at employers who knowingly don't pay what's owed - not at anyone trying to do the right thing.

The point The best protection against any of this is understanding what's required. That's what the rest of this course is for.

Setting up

What you need

The complexity of employment law isn't designed to make life difficult for small employers (thought it can feel that way at times) Most of it is well-handled by good systems and reasonable judgement. Here's the shape of what you'll need:

A payroll system that handles the mechanics PAYE, KiwiSaver, leave calculations, minimum wage checks, payday filing. You need to be able to show what leave each employee has taken, what they have left, and how any payments were calculated. A payroll system will do this for you. These should be automated, not done by hand. Doing payroll manually in 2026 is how mistakes happen. 

Written employment agreements Every employee must have one. The Employment Agreement Builder on business.govt.nz is a free, government-provided tool that walks you through what's required.

‍A good day-to-day relationship This is the part no software handles. How you treat your employees - communicating clearly, acting in good faith, dealing with problems early - is what makes employment work or not. We'll come back to this throughout the course.

The takeaway

You've got this

The employers who do well by their teams aren't necessarily the ones who can quote employment law back to you. They're the ones who pay people correctly and on time, treat people fairly, communicate clearly, and deal with problems early.

Everything else - the mechanics of payroll, the specifics of leave entitlements, the right way to draft an agreement - is learnable. That's what the rest of this course is for.
