Employing staff in New Zealand: what it's really like as a small employer

For a long time, the only person I let down by missing a deadline was myself. Then the business grew enough to need another pair of hands, and the maths in my head changed overnight. It wasn’t really the extra line in the accounts. It was realising that somewhere in a spreadsheet on my screen sat a number that, in a roundabout way, helped keep a roof over someone else’s head too.

I ran 3WhiteHats NZ, now 3WH, as a company director for years, which meant learning to pay a team’s PAYE, KiwiSaver and ACC levies properly, on time, every payday. Dawn now runs operations and accounts at 3WH, and knows exactly how the numbers behave when a KiwiSaver rate changes or a new hire starts mid-month. This guide is built from that, checked against current Employment New Zealand, Inland Revenue, ACC and Immigration New Zealand settings for 2026. If you’ve read our guide to going self-employed in New Zealand, this picks up where that leaves off: it covers sole trader versus company and GST, so we won’t repeat that. This one is about what happens once you’re the employer, not just the business owner.

In this article we discuss:

• The real shift from invoicing to running payroll
• Why written employment agreements aren’t optional
• Minimum wage and getting pay right
• The 90-day trial period, used properly
• Payday filing, and what it actually feels like
• KiwiSaver as an employer, beyond the headline rate
• ACC levies: what you’re actually paying for
• Annual leave, sick leave and the bill that might change it all
• Health and safety: you’re the PCBU now
• Hiring migrant staff and employer accreditation
• Contractors vs employees, and the new gateway test
• Payroll software, honestly assessed

From invoicing to payroll: what actually changes

As a sole trader or a company of one, every financial decision only ever lands on you. Take someone else on, and that stops being true. You’re now responsible for their pay landing correctly and on time, their leave building up properly, their KiwiSaver paid across in full, and a working environment that doesn’t put them at risk. None of it can be quietly deferred to next month the way you might let your own invoicing slide.

Our self-employed guide covers actually registering as an employer with Inland Revenue and getting your employer number sorted before a new hire’s first payday, so we won’t repeat that here. This piece covers what that guide only touches on: what the ongoing obligations actually require, and what they genuinely feel like to run week to week, once someone is depending on you for their pay.

Written employment agreements aren’t optional

Every employee, full time, part time or casual, is legally entitled to a written employment agreement, provided before they start. Skip it, and you’re exposed to an infringement fee of NZD $1,000 (about £427 or US$585 at rates in mid-July 2026), and the Employment Relations Authority can order penalties of up to NZD $10,000 for an individual employer or NZD $20,000 for a company.

We wrote proper agreements for every person we took on, using Employment New Zealand’s own Employment Agreement Builder rather than reinventing the wheel. What surprised me was how much clarity a well-written agreement adds beyond the legal minimum. Pay, hours and leave are the legal skeleton, but the plain-English bits, what the role covers, how performance gets discussed, what happens if either side wants to change something, are what actually saved relationships down the line. A vague agreement doesn’t just risk a penalty; it sets you up for a misunderstanding months in, right when everyone’s memory of “what we agreed” has quietly diverged. If any agreements are old, or someone’s working without one, fix it now.

Minimum wage and getting pay right

From 1 April 2026, the adult minimum wage rises to NZD $23.95 an hour (about £10.24 or US$14.01), up from $23.50. The starting-out and training minimum wage rises to $19.16, up from $18.80. Both are before tax, and apply to all hours worked unless your agreement sets a higher rate, including staff paid by salary, piece rate or commission rather than a straight hourly wage.

Two groups sit outside minimum wage: employees under 16, and disabled employees holding a specific exemption permit issued by a Labour Inspector, a narrow exception rather than something an employer decides alone. Getting the rate right on paper is only half of it. If staff sit close to minimum wage, an increase like this is also a moment to think about pay relativity, because someone who was fifty cents above it last year and is now sitting on it can reasonably expect a conversation, not silence.

The 90-day trial period, used properly

Ninety-day trials used to be limited to employers with fewer than twenty staff. That restriction has gone, and any employer can now offer a new hire a trial covering their first ninety calendar days. The rules are stricter than the pitch sounds: it must be agreed in writing, as part of the employment agreement, before the employee starts, not added retrospectively. It only applies if this is genuinely their first time working for you. It doesn’t touch anything else: you still owe good faith, correct pay, proper conditions, leave and a safe workplace throughout. And Immigration New Zealand doesn’t allow a trial at all for anyone hired on an Accredited Employer Work Visa, whatever the agreement says.

We used trial periods sparingly and treated them exactly as intended: a genuine two-way check that a role was the right fit, not a loophole to avoid a difficult conversation later.

Payday filing: what it actually feels like

Payday filing means exactly what it says: every time you pay staff, you file employment information with Inland Revenue for that pay run, within two working days, rather than one tidy monthly return. In practice, once decent payroll software is set up, this becomes routine: run the pay, the software calculates PAYE, KiwiSaver, student loan deductions and ACC earners’ levy, and the filing goes across automatically. What takes getting used to is the discipline underneath it. Deductions still have to be paid across, typically by the 20th of the following month if your total annual PAYE and ESCT is under NZD $500,000, or twice monthly above that, and the two-day window doesn’t forgive a holiday or a bad week. It’s less like invoicing, where a delay is annoying but recoverable, and more like a standing appointment you can’t quietly move. Get the routine right early and it’s background noise. Leave it manual too long and it eats your Friday afternoons every fortnight.

KiwiSaver as an employer, beyond the headline rate

Our self-employed guide and our pros and cons of KiwiSaver both cover the headline number: the employer minimum rose from 3% to 3.5% of gross pay from 1 April 2026, rising again to 4% from 1 April 2028. Worth adding, from actually running it: that contribution isn’t simply added on top and left alone. It’s subject to employer superannuation contribution tax, ESCT, deducted from the contribution before it reaches the employee’s account, at a rate set by that individual’s earnings, not a flat figure across your team. Two staff on different pay can have different ESCT rates applied to what looks like the same contribution, and getting that wrong is a common payroll error among smaller employers, usually from treating KiwiSaver as one flat line rather than something calculated per person, per pay run.

Employees can apply to temporarily reduce their own rate back to 3% if the increase is a genuine stretch, and your contribution matches it. Worth knowing that exists before a staff member raises it mid-conversation.

ACC levies: what you’re actually paying for

ACC touches your payroll two separate ways. Your employees’ earners’ levy, currently $1.75 per $100 of earnings for the year running 1 April 2026 to 31 March 2027, capped at $156,641, comes off their own pay through PAYE; that isn’t really your cost, you’re just collecting and passing it on. What is genuinely your cost is the Work Levy, invoiced separately based on your total payroll and your classification unit, the industry and risk category ACC has assigned you. Low-risk office work sits at the cheap end, higher-risk trades well above it, and the average Work Levy for 2026/27 moved during consultation, so rather than quote a figure that might already be stale, check ACC’s levy calculator against your own classification. A smaller Workplace Safety Levy, flat across all industries, sits on top.

Your invoice typically lands a few months after your return is filed, and once you’ve paid at least three Work Levy invoices, ACC can move you onto its Experience Rating programme, adjusting your rate on actual claims history and safety performance.

Annual leave, sick leave and the bill that might change it all

Under the current Holidays Act 2003, every employee becomes entitled to four weeks of annual leave after twelve months’ continuous employment, and eligible employees get ten days of paid sick leave a year to look after themselves, a partner or a dependant. Those are the numbers to budget around today.

Worth flagging honestly, because it’s genuinely moving as we write this: the Employment Leave Bill, intended to replace the Holidays Act, was reported back by the Education and Workforce Committee on 15 July 2026 recommending it pass, with the core proposal broadly intact: annual and sick leave accruing from day one in hours rather than as annual entitlements, plus a new “otherwise working day” test for public holidays. It hasn’t passed yet, and if it does, there’s a proposed implementation period of around two years to give employers and payroll providers time to adjust. Until then, the current Holidays Act rules apply in full. Know this is coming, but don’t build today’s system around a bill that hasn’t had its final readings.

Health and safety: you’re the PCBU now

Under the Health and Safety at Work Act 2015, every business is a PCBU, a person conducting a business or undertaking, and as the employer, that’s you. The primary duty of care means ensuring, so far as is reasonably practicable, the health and safety of everyone who works for you, and that your work doesn’t put anyone else at risk.

For a small, office or desk-based business, “reasonably practicable” doesn’t mean elaborate policy documents nobody reads. It means thinking through what could realistically go wrong for people working for you, from a poor workstation to the mental load of an unreasonable deadline, and doing something sensible about it: adequate facilities, the training people actually need, and taking it seriously if someone raises a concern. If your work involves any physical risk, tools, vehicles, client sites, that duty gets correspondingly more hands-on. This isn’t box-ticking. It’s about being the person responsible if something goes wrong, because legally, you are.

Hiring migrant staff and employer accreditation

To hire someone who needs a work visa, you generally need to become an accredited employer under the Accredited Employer Work Visa, AEWV, scheme before offering them the job. Standard accreditation covers hiring up to five migrant workers; high-volume accreditation is for six or more. Immigration New Zealand assesses whether your business is genuine, financially sound, and has a clean history of meeting employment and immigration obligations, and there are currently more than 29,000 accredited employers and over 79,000 AEWV holders, a well-worn path rather than an obscure one.

Two details catch small employers out. Accreditation must be approved before you can support a job offer, not sorted retrospectively once a candidate has accepted. And, as above, a 90-day trial simply isn’t available for AEWV holders. If hiring from overseas is part of your growth plan, our guide to finding a job in New Zealand covers the jobseeker side, useful for understanding what your future hires are already navigating.

Contractors vs employees, and the new gateway test

Getting this distinction wrong is one of the more expensive mistakes a small employer can make: a worker treated as a contractor who’s actually functioning as an employee can bring a personal grievance, claim back pay and holiday pay never paid, and expose you to ERA penalties on top.

The law shifted this year. A new “gateway test” came into force on 21 February 2026, not retrospective, so arrangements that started before that date are assessed under the old common law test only, while anything current is assessed under both. A worker counts as a specified contractor, sitting outside employment law protections, if all of the following hold: a written agreement states they’re an independent contractor (or not an employee), they’re free to work for someone else (just not at the same time as working for you), they can choose when to work or can subcontract the work to someone else, the arrangement doesn’t end simply because they turned down extra work, and they had a reasonable chance to get independent advice before signing. Meet all five, and the classification is settled cleanly. Miss any one element, and it falls back to the existing common law test, looking at control, integration and economic reality, considerably less predictable and one that’s caught plenty of well-meaning employers out.

Our practical rule: if someone works set hours, uses your equipment, takes direction on how (not just what) to do the job, and effectively can’t say no to extra work without it affecting the relationship, treat them as an employee, whatever the invoice says. Legal advice on a genuinely borderline case, before you sign anything, is far cheaper than untangling it afterwards.

Payroll software, honestly assessed

Nobody sensible runs payroll for more than one person on a spreadsheet for long. Xero, which is what we used and still recommend, handles PAYE calculation, payday filing, KiwiSaver deductions and ESCT automatically once configured, and there are several other solid New Zealand-specific options built around the same requirements. What software can’t do is replace judgement: it files the numbers correctly and on time, but it won’t catch a wrongly classified contractor, spot someone’s still on last year’s minimum wage, or notice an agreement is quietly out of date. It runs the mechanics. You’re still responsible for the decisions feeding into it.

Your questions answered

Do I need to provide a written employment agreement to a casual staff member who only works a few shifts a month? Yes. The requirement applies to every employee, including genuinely casual and part-time staff. There’s no minimum hours threshold that exempts you.

Can I use a 90-day trial on someone who worked for me casually two years ago and is now coming back full time? No. The trial only applies if the person hasn’t previously worked for you in any capacity, whatever the new role looks like.

What happens if I genuinely can’t afford the KiwiSaver contribution increase to 3.5%? There’s no employer-side exemption from the minimum rate. Employees facing genuine affordability pressure can apply for a temporary reduction back to 3%, which your contribution then matches, but the decision sits with the employee, not you.

Do I still owe ACC’s Work Levy if none of my staff have ever made a claim? Yes. It’s calculated on your payroll and industry classification regardless of claims history, though a clean record over time can move you onto ACC’s Experience Rating programme, which can reduce what you pay.

If someone works for me under a genuine, correctly structured contracting arrangement, do I still owe them KiwiSaver or ACC earners’ levy? No, not through you. A correctly classified independent contractor manages their own ACC cover (typically CoverPlus) and KiwiSaver directly, because they aren’t your employee. Getting the classification wrong is exactly what turns this answer around.

Does the 90-day trial let me avoid paying someone if I decide not to keep them? No. You still have to pay them correctly for every hour worked, at or above minimum wage and in line with their agreement. The trial only affects their ability to bring a personal grievance about the dismissal itself, not their pay for time already worked.

Is there a minimum number of staff before health and safety duties under HSWA apply to me? No. The PCBU duty applies from your first employee, and from the moment your business could put anyone at risk through its work. There’s no small-business exemption.

The bit we can’t write for you

Everything above is how the system works and how we’ve navigated it ourselves, across years of being an employer rather than just self-employed. It isn’t legal or employment advice, and some of what’s covered here, the Employment Leave Bill especially, and the new contractor gateway test, is actively moving or new enough that the detail is still settling in practice. For anything that matters to your own situation, check the current position directly on employment.govt.nz, with Inland Revenue, ACC or Immigration New Zealand, or with an employment lawyer for anything genuinely borderline, rather than relying on a blog post, including this one.

We’re working on a fuller, paid guide that goes deeper into actually running a small team here: recruitment, performance conversations, restructuring done properly, and what we’d genuinely do differently a second time round.
