Work Trials in New Zealand

Hiring your next team member is exciting - but it can also feel like a big leap, especially if you're a small business and every hire counts.

That's where a work trial can seem like the perfect middle ground. You get to see how someone actually performs in your workplace, and they get to see whether the role (and your business) is the right fit.

But before you bring someone in "just to try it out", it's important to understand how work trials are treated in New Zealand. If you get it wrong, a trial can quickly turn into a legal headache - from wage claims to disputes about employment status.

Below, we break down how a work trial can work in practice, what the legal risks are, and the practical steps you can take to protect your business from day one.

What Is A Work Trial (And Why Do Employers Use Them)?

A work trial is when you ask a candidate to perform tasks (usually for a short period) so you can assess whether they can do the job and whether they're a good fit for your team.

For small businesses, the appeal is obvious. A CV and interview can only tell you so much. A trial can help you assess things like:

their technical ability (can they actually do what they said they can?)
their communication style with customers and staff
how they handle pressure during busy periods
whether they follow your systems and processes
cultural fit and attitude

Done properly, work trials can reduce the risk of a "bad hire" and save time and cost long-term.

Done poorly, they can expose you to claims that you've engaged someone as an employee without meeting your legal obligations (like paying wages and meeting minimum employment standards).

Are Work Trials Legal In New Zealand?

Work trials can be legal in New Zealand, but the key issue isn't what you call something. The key issue is what actually happens in practice.

In many situations, a work trial will look and feel like "work". If someone is performing work for your business, you can be exposed to obligations under New Zealand employment law (including minimum pay requirements) if the arrangement is, in substance, an employment relationship. Minimum standards generally can't be waived just because someone agrees to them.

As a practical way to approach it:

If the person is doing productive work that benefits your business (especially if it resembles an ordinary shift, or you're relying on them as part of your staffing), it's safest to assume they should be paid at least the minimum wage.
If you're running a genuine skills assessment (limited, controlled, closely supervised, and primarily for evaluation rather than output), you may be able to structure it as a brief assessment. Even then, paying for the time is often the lowest-risk approach.

There isn't a one-size-fits-all rule, because the legal risk depends on the reality of the arrangement: the tasks, the supervision, the length of the trial, and whether the person is effectively filling a normal role. Where disputes arise, the question is often whether the person was really an "employee" (based on the real nature of the relationship, not just labels).

It's also worth remembering that even if someone agrees to an unpaid trial, that doesn't automatically make it lawful. For example, minimum employment standards under the Employment Relations Act 2000, Minimum Wage Act 1983, and the Holidays Act 2003 generally can't be "contracted out of".

The Key Legal Risks If You Get A Work Trial Wrong

If a work trial is treated as unpaid labour (even unintentionally), you can expose your business to:

wage claims for unpaid work (including minimum wage and, depending on whether an employment relationship existed and the circumstances, potential entitlements under the Holidays Act)
penalties for failing to meet minimum employment standards
disputes about employment status (for example, a claim that they were actually an employee from day one)
health and safety liability if they're injured on-site while trialling
reputational damage (particularly if the person posts publicly about "unpaid trials")

So even though work trials are common, it's important to set them up carefully and document the arrangement clearly.

Work Trial Vs Trial Period: What's The Difference?

This is one of the biggest sources of confusion for employers.

A work trial is usually something you do before you formally hire someone, to assess them in practice.

A trial period is a specific concept under New Zealand employment law that applies after someone becomes your employee. The most well-known version is the "90-day trial period", which (if you're eligible to use it and you set it up correctly) can limit an employee's ability to bring a personal grievance for unjustified dismissal during the trial period.

However, trial periods are technical and can be invalid if they're not implemented correctly. For example, if a trial period clause is missing key requirements, isn't agreed in writing, or isn't in place before the employee starts work, you may not be able to rely on it.

That's why it's important to have a properly drafted Employment Contract in place before your employee starts, including any relevant trial period terms if you intend to use them.

In other words:

A work trial is about assessing a candidate before hiring (but you still need to be careful about payment and obligations).
A trial period is an employment relationship tool after hiring (and it needs correct drafting and process).

How To Run A Work Trial The Right Way (Practical Steps For Employers)

If you want to use a work trial as part of your recruitment process, the goal is to structure it so it's fair, lawful, and clearly documented.

Below is a practical approach many small businesses take to reduce risk.

1. Be Clear About The Purpose Of The Work Trial

Before you invite a candidate in, ask yourself: what are you actually trying to test?

For example:

Are you testing a barista's coffee-making skills?
Are you testing a receptionist's phone manner and ability to use a booking system?
Are you testing a tradesperson's approach to safety, measurements, and workmanship?

The clearer the purpose, the easier it is to keep the trial short, controlled, and focused (instead of becoming a full shift of unpaid work).

2. Keep The Trial Short And Structured

The longer the work trial goes, the harder it is to argue it's just an assessment.

In many cases, a practical skills assessment can be done in a short block (for example, 1?3 hours depending on the role). If you need longer than that, it's often safer to treat it as a paid shift (or proceed to employment with a properly drafted contract and trial period, if applicable).

Also, make it structured. A good work trial is more like an "on-the-job test" than normal staffing coverage. That means you should:

assign specific tasks that demonstrate the skills you're assessing
supervise the person closely
avoid relying on them to "keep the business running"

3. Put The Work Trial Terms In Writing

Even for a short trial, writing down the basics can save you a lot of confusion later.

Your work trial document (or email confirmation) should ideally cover:

the date, start time, and end time
the location of the trial
what tasks they will be doing (and what they won't be doing)
who will supervise them
whether it is paid, and if so, the rate and how it will be paid
that it is an assessment and does not guarantee employment
confidentiality expectations (especially if they will see customer lists, pricing, or internal systems)

If you're also sharing sensitive business information during recruitment, it may be worth using an Non-disclosure agreement for added protection.

4. Don't Forget Health And Safety

Even if you consider the person to be "just trialling", they're still in your workplace - and that triggers real health and safety responsibilities.

Under the Health and Safety at Work Act 2015, you must take reasonably practicable steps to ensure people are not put at risk while at your workplace. That can include candidates, visitors, contractors, and others who may be affected by your work.

So for a work trial, make sure you:

provide a quick safety induction before they start
explain any hazards relevant to the tasks
provide any required PPE (if applicable)
don't let them use equipment unless you're satisfied they're trained/supervised

This is one of those areas where "keeping it informal" can backfire - because an injury during a work trial can be very serious for everyone involved.

5. Make Sure The Trial Doesn't Become A Substitute For Proper Hiring

A work trial is best used as the final step after you've already assessed the candidate through your normal recruitment process.

If you find yourself running repeated trials with multiple candidates to cover shifts, it's a sign the process is drifting into risky territory. At that point, you may want to tighten your hiring process and documentation.

Having strong systems in place - including clear role descriptions, consistent onboarding, and the right employment documentation - can help you hire with confidence. For example, many small businesses benefit from having a broader Staff Handbook to set expectations about conduct, rosters, policies, and workplace rules.

Should You Pay Someone For A Work Trial?

As a practical risk-management approach, many employers choose to pay for a work trial - especially where the trial involves:

doing real work that benefits the business
interacting with customers
covering a role that would otherwise require a paid staff member
working for more than a brief "skills test" period

Paying for a trial can feel frustrating if you're worried about paying someone who isn't ultimately hired. But it often costs far less than dealing with a dispute later.

If you do pay a work trial, you'll want to be clear on:

what the pay rate is (at least minimum wage, and sometimes higher depending on the role)
how you'll record time worked
when it will be paid (for example, in the next payroll cycle)
whether you will reimburse any expenses (if relevant)

If you're unsure whether your planned trial should be paid, it's worth getting advice upfront. This is exactly the kind of issue where a small tweak in structure and wording can prevent bigger problems later.

What Other Legal Documents Should You Have In Place When Hiring?

A work trial is only one piece of the hiring puzzle. If the trial goes well and you want to hire the candidate, the next step is making sure your legal foundations are solid.

Here are a few documents and legal areas that commonly matter for small businesses hiring in New Zealand.

Employment Agreements

Once you decide to hire, you'll want the right agreement in place before they start. This is where you set expectations around pay, hours, duties, confidentiality, IP ownership (if relevant), and termination.

Depending on the role, you might need a full-time, part-time, or casual arrangement - and the terms should match what you're actually offering.

If you're engaging someone as an employee, a tailored Employment Contract is the starting point.

Contractor Agreements (If They're Not An Employee)

Sometimes business owners use work trials when they're planning to engage a contractor rather than an employee. This can happen in trades, marketing, IT, admin support, or seasonal work.

Be careful here. Whether someone is a contractor or an employee isn't just about what you call them - it's about the real nature of the relationship.

If you're engaging an independent contractor, it's still important to document the arrangement properly with a Contractor Agreement (including scope, payment, ownership of work product, and liability settings).

Privacy And Candidate Information

Recruitment involves collecting personal information - CVs, reference details, interview notes, and sometimes IDs or background checks.

If your business collects and stores personal information, you should make sure your practices align with the Privacy Act 2020. For many businesses, this also means having a clear Privacy Policy (particularly if you recruit through your website or keep digital records).

Confidentiality And Protecting Your Business Information

During a work trial, candidates can see sensitive information like:

supplier pricing
customer databases
internal processes and templates
commercial terms and quoting methods

Confidentiality clauses in employment agreements help, but for pre-employment stages (including work trials), a separate confidentiality document can be useful. In some cases, a Non-disclosure agreement is a practical way to set expectations clearly.

Common Mistakes Employers Make With Work Trials (And How To Avoid Them)

Work trials usually go wrong for one reason: they're treated too casually.

Here are some common pitfalls we see, and what you can do instead.

Running A "Trial Shift" During Your Busiest Service

If the candidate is thrown into a peak lunch rush and expected to keep up like a paid staff member, it looks much less like an assessment and much more like unpaid labour.

What to do instead: schedule a structured trial during a quieter period, or make it a paid trial shift with proper payroll processes.

Not Documenting Anything

If there's a dispute later, a lack of written terms makes it harder to show what was agreed.

What to do instead: confirm the trial details in writing (even an email can help), including hours, duties, and whether it's paid.

Letting Trials Run Too Long

A one-hour practical assessment is easier to justify than an unpaid week "to see how it goes".

What to do instead: keep the work trial short and focused. If you need a longer period to assess performance, consider hiring under an employment agreement with a compliant trial period clause (where applicable).

Using A Template That Doesn't Match Your Situation

It can be tempting to grab a generic letter or clause online. But recruitment and employment documents need to reflect how your business actually operates.

What to do instead: get your documents tailored - it's one of the simplest ways to protect your business and reduce disputes later.

Key Takeaways

A work trial can be a useful way to assess candidates in real conditions, but it needs to be structured carefully so it doesn't become unpaid productive work.
Whether a work trial is lawful depends on what happens in practice - not what you call it - so keep trials short, supervised, and assessment-focused (and consider paying as a low-risk option).
A work trial is different from a trial period, which applies after hiring and needs to be set up correctly in an employment agreement.
To reduce risk, confirm the work trial terms in writing, including tasks, timeframes, supervision, and whether the trial is paid.
Health and safety still applies during a work trial, so make sure you provide an induction and manage workplace risks.
Once you hire, protect your business with the right legal documents, such as an Employment Contract, and consider confidentiality and privacy protections as part of your hiring process.
