How To Lawfully Dismiss An Employee In New Zealand

Letting someone go is one of the hardest parts of running a small business. It’s also one of the quickest ways to end up in an expensive dispute if you don’t follow a fair and lawful dismissal process.

In New Zealand, you generally can fire someone - but you can’t do it casually, on the spot, or “just because it’s not working out” without taking the right steps. The law expects employers to act fairly, communicate properly, and make decisions that a fair and reasonable employer could make in the circumstances.

This guide breaks down what a good dismissal process looks like in practice, so you can protect your business while treating your employee with basic fairness and respect.

Can You Fire Someone In NZ? (And What The Law Expects From Employers)

Yes, employers can dismiss employees in New Zealand. But it must be done lawfully and fairly.

The core rules come from the Employment Relations Act 2000, which requires employment relationships to be conducted in good faith. In plain terms, that means you should be honest, communicative, and genuinely consider the employee’s response before making a final decision.

A lawful dismissal process is usually built on two pillars:

• Substantive justification: you need a valid reason (for example, misconduct, poor performance, or redundancy).
• Procedural fairness: you need to follow a fair process (for example, investigate, raise concerns, allow a response, and consider alternatives).

If either pillar is missing, you can face a personal grievance claim (for example, unjustified dismissal), even if you feel the decision was “obvious”.

It’s also important to check your starting point: the employee’s Employment Contract. A well-drafted agreement usually sets expectations around conduct, performance, notice periods, and disciplinary steps, which helps make the dismissal process clearer and more defensible.

What Are The Common Reasons For Dismissal?

Most dismissals fall into a few common categories. The reason matters because it shapes the dismissal process you need to follow.

1) Misconduct And Serious Misconduct

Misconduct is behaviour that falls below expected standards (for example, repeated lateness, failure to follow reasonable instructions, or inappropriate conduct).

Serious misconduct is more severe behaviour that can justify dismissal without notice in some cases (for example, theft, violence, serious dishonesty, or serious breaches of health and safety).

Even with serious misconduct, you usually still need a fair process. “Serious” doesn’t always mean “instant”. In some situations you may need to require an employee to leave the workplace immediately (for example, to manage safety, protect evidence, or prevent disruption), but you should still follow a fair process before reaching a final decision.

2) Poor Performance (Including Not Being The Right Fit)

“They’re not the right fit” often translates to performance issues, capability issues, or a mismatch between role expectations and the employee’s output.

Poor performance dismissals usually require the most careful process because you’ll generally need to show you:

• identified the performance issues clearly;
• set reasonable expectations and timeframes;
• provided support, training, or guidance where appropriate; and
• gave genuine opportunities to improve.

If you’re managing performance concerns, a structured approach matters. Many employers choose to document these steps using a consistent performance management process so expectations, timeframes, and outcomes are clear.

3) Medical Incapacity Or Health-Related Issues

This is a sensitive area. If an employee can’t perform their role due to illness or injury, dismissal might be possible, but only after a careful and fair process.

As an employer, you’ll usually need to consider things like:

• how long the employee has been unwell (and likely timeframe for return);
• whether duties can be temporarily adjusted;
• whether there are reasonable accommodations; and
• medical information (handled carefully and lawfully).

If you’re collecting or storing medical information, remember your obligations under the Privacy Act 2020 and general confidentiality expectations.

4) Redundancy (Role No Longer Needed)

Redundancy is not “firing” someone for performance or conduct. It’s ending employment because the job is no longer required due to genuine business reasons (for example, restructure, downturn, loss of a major contract, or technological change).

Redundancy has its own consultation requirements and risk points. If redundancy is on the table, getting tailored guidance early can save you headaches later, including advice on Redundancy Advice.

A Step-By-Step Dismissal Process For Employers (A Practical Checklist)

If you’re looking for “best practice”, think of the dismissal process as a sequence: identify the issue, raise it fairly, allow a response, consider options, then decide.

Here’s a practical step-by-step approach that works for many common situations (especially misconduct and performance).

Step 1: Get Clear On The Issue And The Evidence

Before you say anything to the employee, get your facts straight. Ask:

• What happened (specifically)?
• When did it happen?
• What evidence do we have (emails, time records, CCTV policy-compliant footage, witness notes)?
• What policies or contractual obligations are relevant?
• Is it misconduct, performance, or something else?

A common mistake is starting the process based on frustration, assumptions, or hearsay. If it ends up in the Employment Relations Authority, you’ll want to show your decision was based on reasonable grounds.

Step 2: Consider Whether Suspension Or “Special Leave” Is Needed

In some situations (particularly alleged serious misconduct), you may need to remove the employee from the workplace while you investigate.

This must still be handled carefully. Suspension isn’t automatic, and you should usually consider it only where it’s necessary (for example, to protect people, protect evidence, or prevent serious disruption). You should also check the employment agreement and any workplace policies, and give the employee a chance to comment on a proposed suspension before you decide (where it’s practicable to do so).

If you do suspend, communicate it in writing, keep it as short as reasonably possible, and continue to act in good faith.

Step 3: Put The Concerns In Writing And Invite Them To A Meeting

Next, you’ll usually issue a letter that:

• explains the concerns clearly (with enough detail to respond);
• explains that dismissal is a possible outcome (if that’s genuinely on the table);
• invites the employee to a meeting at a reasonable time;
• advises they can bring a support person or representative; and
• includes relevant information you will rely on (where appropriate).

This step is central to a fair dismissal process because it gives the employee a real opportunity to understand the allegations or concerns.

Step 4: Hold A Fair Meeting (And Actually Listen)

At the meeting, your job is to explain the concerns and genuinely consider what the employee says.

Some practical tips:

• Stay calm and professional (avoid debating or interrupting).
• Ask clarifying questions rather than making accusations.
• Take notes, and keep them factual.
• If new information comes up, pause and investigate rather than deciding on the spot.

If the employee asks for a short adjournment to get advice or gather information, consider whether that’s reasonable in the circumstances.

Step 5: Investigate Properly (If Needed)

In many cases, the meeting will raise issues you need to check. For example:

• there are conflicting accounts of an incident;
• there are mitigating factors (health, training gaps, unclear instructions); or
• there are allegations against another staff member too.

A fair and reasonable employer would usually investigate those points before deciding. Skipping this step is a common reason dismissals are challenged.

Step 6: Consider Alternatives To Dismissal

Dismissal should not be your “default” outcome unless the situation genuinely warrants it. Depending on the facts, alternatives might include:

• training or closer supervision;
• a performance improvement plan (PIP);
• a warning (verbal or written, properly documented);
• mediation or resolving interpersonal conflict;
• adjusting duties (where possible); or
• final warning (for repeated misconduct).

It’s not that you must try every alternative. But your dismissal process should show you considered what was reasonable.

Step 7: Make A Decision And Communicate It In Writing

Once you’ve gathered the information and considered the employee’s response, you can decide on the outcome.

Your outcome letter should usually:

• set out what was considered (including their explanation);
• set out findings (what you consider happened, on reasonable grounds);
• explain why the outcome is justified; and
• confirm notice, final pay, and next steps (returning property, handover, etc.).

If you want a clean and consistent approach, many employers prepare a set of documents in advance so they’re not drafting “under pressure” mid-process. This is where an Employee Termination Documents Suite can be helpful, especially if you anticipate needing formal letters and supporting documents.

Notice Periods, Final Pay, And Payment In Lieu Of Notice

Even if you follow a fair dismissal process, you still need to end employment correctly from a pay and entitlements perspective.

Do You Have To Give Notice?

In many cases, yes. Notice periods are usually set out in the employment agreement.

However, if the situation is serious misconduct, dismissal may be summary (without notice) if that outcome is justified and the process is still fair.

What Should Be Paid Out On Termination?

Final pay commonly includes:

• any wages/salary owing up to the last day worked;
• unused annual holidays (payable on termination under the Holidays Act 2003);
• any other amounts due under the employment agreement (for example, commission rules, if applicable); and
• any contractual payments you’ve agreed to (for example, notice pay).

Can You Pay In Lieu Of Notice?

Sometimes you may want the employee to leave immediately, even though they are entitled to notice (for example, for operational reasons, customer relationships, or workplace tension).

Whether you can do that depends on the contract wording and the circumstances. If you’re considering it, it’s worth understanding payment in lieu of notice and how to document it properly so you don’t accidentally create additional risk.

Also be cautious about “forcing” someone to use annual leave during the notice period. There are rules around when an employer can direct annual leave (including notice requirements under the Holidays Act 2003), and in some cases it may require agreement or proper notice - so get advice specific to your situation.

Common Dismissal Process Mistakes Small Businesses Should Avoid

When you’re busy running a business, it’s easy to jump straight to the outcome. Unfortunately, dismissal is one area where shortcuts tend to backfire.

Here are common pitfalls we see in NZ workplaces.

Dismissing On The Spot Without A Process

Even where you’re confident the employee did something wrong, instant dismissal without investigation, written notice of concerns, and a chance to respond is a major red flag.

Failing To Explain The Concerns Clearly

Vague statements like “your attitude isn’t right” or “we’re not happy with your performance” aren’t enough. A fair dismissal process requires specific examples and a clear explanation of what needs to improve.

Predetermining The Outcome

If you go into the meeting having already decided to fire them, you haven’t genuinely considered their response. That’s a classic procedural fairness issue.

Treating Redundancy Like Performance Management

Redundancy is about the role, not the person. If the real issue is performance, calling it “redundancy” can create significant risk (including allegations that the redundancy was not genuine).

Not Following Your Own Policies Or Contract

If you have a disciplinary policy, follow it. If your contract sets steps, follow them. Inconsistent treatment can quickly become a dispute.

Forgetting Privacy And Confidentiality

Dismissals often involve sensitive information. Be careful about who you share details with internally, and ensure any personal information is handled in line with the Privacy Act 2020.

Key Takeaways

• A lawful dismissal process in New Zealand needs both a valid reason (substance) and a fair process (procedure), in line with the Employment Relations Act 2000 and good faith obligations.
• Most dismissals fall into misconduct, serious misconduct, poor performance/capability, medical incapacity, or redundancy, and each category can require a different approach.
• A fair dismissal process usually includes: clarifying allegations, providing information in writing, inviting a response meeting (with a support person option), investigating where necessary, considering alternatives, and confirming the decision in writing.
• Notice periods, final pay, and leave payouts must be handled correctly, and payment in lieu of notice should be documented carefully.
• Common mistakes include firing on the spot, being vague about concerns, predetermining the outcome, mixing up redundancy with performance issues, and failing to follow your own contract/policies.
• Having the right documents and a consistent approach (like an up-to-date Employment Contract and a clear performance management process) can significantly reduce risk.
