Wrongful Dismissal Vs Unfair Dismissal: What’s The Difference? (2026 Updated)

If you’ve ever had to let someone go (or you’re worried you might need to), the terms “wrongful dismissal” and “unfair dismissal” can start flying around pretty quickly.

They sound similar, but they’re not the same thing - and mixing them up can lead to costly mistakes, stressed-out staff, and avoidable disputes.

This guide is updated for current practice and expectations, so you can feel confident you’re dealing with dismissal the right way, with the right process, from day one.

What Do “Wrongful Dismissal” And “Unfair Dismissal” Mean In NZ?

In New Zealand, “unfair dismissal” is the term you’ll hear most often in everyday conversations, but legally, we usually talk about an employee raising a personal grievance for unjustified dismissal under the Employment Relations Act 2000.

“Wrongful dismissal” is also used in NZ, but it usually refers to a different kind of issue - more about breach of contract (for example, not giving the notice required by the employment agreement).

So, a simple way to think about it is:

• Wrongful dismissal is usually about whether you broke the employment agreement when ending employment (contract issue).
• Unfair dismissal is usually about whether the dismissal was unjustified and/or the process was unfair (fairness and reasonableness issue).

In real life, these issues often overlap. For example, if you dismiss someone on the spot without following a fair process and you don’t pay notice, you could be looking at both types of claims.

Wrongful Dismissal: When It’s A Contract Problem

Wrongful dismissal is commonly used to describe situations where the employer ends employment in a way that breaches the employment agreement.

That might include:

• Not giving the correct notice period (or not paying out the notice period when required).
• Dismissing someone in a way that breaches an agreed disciplinary or termination clause.
• Terminating contrary to a fixed-term agreement (for example, ending early without a contractual right to do so).

Notice Periods And “Payment In Lieu”

A very common wrongful dismissal scenario is where an employee is told not to come back, but the employer doesn’t provide what the contract requires (usually notice or payment instead of notice).

If your agreement allows it, you might be able to end employment immediately by making a payment in lieu of notice. If it doesn’t, you may need to give working notice (or negotiate an exit).

This is one of those areas where “doing what feels practical” can backfire if it’s not supported by the contract.

Fixed-Term Contracts And Early Termination

If someone is employed on a genuine fixed-term basis, you generally can’t just end the employment early because the role isn’t working out. You still need:

• a lawful basis to terminate early (often written into the contract), and
• a fair process (even if the contract gives you a right to end early).

Fixed-term arrangements are a common source of disputes when they aren’t set up correctly or the termination clause is unclear. If you’re using fixed-term arrangements, it’s worth ensuring your Employment Contract is properly drafted and fit for purpose.

Is “Wrongful Dismissal” Always About Money?

Often, yes. Wrongful dismissal claims typically focus on contractual losses, such as unpaid notice, unpaid wages, or other entitlements that should have been paid under the agreement.

But remember - a contract breach can sit alongside an unjustified dismissal claim, which can expand the risk significantly.

Unfair Dismissal (Unjustified Dismissal): When It’s About Fairness And Process

When people say “unfair dismissal” in New Zealand, they usually mean a dismissal that wasn’t justified or wasn’t handled fairly.

In practice, that’s often raised as a personal grievance for unjustified dismissal.

In broad terms, the key question is whether the employer acted as a fair and reasonable employer would in the circumstances.

What Makes A Dismissal “Unjustified”?

There are two big pieces to this:

• Substantive justification: Was there a good reason to dismiss?
• Procedural fairness: Did you follow a fair process before deciding?

You generally need both. Even if you think you have a solid reason, a poor process can still lead to a finding of unjustified dismissal.

Common Reasons Employers Dismiss Staff (And Where Things Go Wrong)

Some of the most common dismissal contexts include:

• Misconduct / serious misconduct: e.g. theft, violence, serious breach of policy, or repeated misconduct after warnings.
• Poor performance: where the employee isn’t meeting the requirements of the role.
• Medical incapacity: long-term illness/injury affecting their ability to perform their role.
• Restructures / redundancy: where the role is genuinely no longer required.

Where employers often get into trouble is assuming that a “good reason” means they can move quickly without proper steps. But dismissal is one of the highest-risk actions you can take as an employer, so process really matters.

What Does A “Fair Process” Usually Involve?

While every workplace situation is different, a fair process often includes:

• clearly explaining the concerns (and the potential consequences),
• giving the employee a genuine opportunity to respond,
• considering their explanation with an open mind,
• carrying out reasonable investigation where required,
• considering alternatives to dismissal (where appropriate), and
• confirming the decision in writing, with clear reasons.

It can feel formal - especially for small business owners hiring their first team members - but it’s part of building good employment foundations and protecting your business.

If you don’t have one already, a well-drafted Workplace Policy (and a clear disciplinary process inside it) can make these situations much easier to manage.

Key Differences At A Glance (And Why It Matters)

If you’re trying to work out which concept applies to your situation, these comparisons help.

1. The Focus Of The Claim

• Wrongful dismissal: focuses on whether you breached the employment agreement (for example, notice, pay, or a contractual termination clause).
• Unfair/unjustified dismissal: focuses on whether the dismissal decision and process were fair and reasonable.

2. The Evidence That Matters

• Wrongful dismissal: the written employment agreement, notice provisions, payroll records, and any written termination communications matter a lot.
• Unjustified dismissal: meeting notes, investigation steps, warning letters, performance plans, and evidence that you considered the employee’s response become crucial.

3. The Risk Profile

Wrongful dismissal often results in a more “contained” dispute (e.g. paying out a notice period that should have been paid).

Unjustified dismissal can lead to broader remedies, including reimbursement of lost wages and compensation for hurt and humiliation - plus legal costs and management time.

That’s why it’s so important not to treat dismissal as a purely operational issue. It’s a legal process, and it needs to be handled carefully.

4. They Can Happen Together

This is the part many business owners miss: one dismissal can trigger both issues.

For example:

• You dismiss an employee immediately without a proper meeting or investigation (process issue), and
• you also don’t pay notice (contract issue).

That can mean you’re dealing with both an unjustified dismissal grievance and a contractual claim.

Common Scenarios For NZ Employers (And What To Do Instead)

Most dismissals aren’t driven by “bad intentions”. They happen because a situation escalates, you’re busy, and you want to protect your business.

Here are a few scenarios where the difference between wrongful and unfair dismissal really matters.

Scenario 1: “They Resigned Without Notice - Can I Just End It Now?”

If an employee resigns without giving the notice required by their employment agreement, you might feel like you can simply accept it and move on.

But there are still risks around final pay, deductions, and whether you treat the resignation as effective immediately (or negotiate an earlier end date).

This comes up so often that it’s worth having a clear approach (and clear contractual wording). If you’re dealing with this, the principles in resigning without notice are a helpful starting point.

Scenario 2: “It’s Not Working Out - I’ll Just Let Them Go During Probation”

Many employers assume a trial period or probation period means they can terminate employment easily.

But you still need to:

• make sure the trial/probation clause is valid and properly documented, and
• follow a fair process appropriate to the situation.

If you dismiss someone “because it’s not working out” without giving them feedback or a chance to respond, you’re increasing your risk of an unjustified dismissal claim (even if you believe the decision is reasonable).

This is why it’s so important to get your Employment Contract right from the start - it sets expectations and gives you a roadmap for handling issues properly.

Scenario 3: “Business Is Quiet - I Need To Reduce Their Hours”

Reducing hours can be a genuine business need, but it’s not something you can usually do unilaterally unless your agreement clearly allows it.

If you cut hours without agreement or consultation, you may be breaching the contract (which can look like a wrongful dismissal-style issue) and potentially creating grounds for a personal grievance if the changes are significant.

If this is on your radar, the steps around consultation and agreement are crucial - the practical issues in reducing staff hours are closely connected to dismissal risk too.

Scenario 4: “I’m Restructuring - Is This A Redundancy?”

Redundancy isn’t a “label” you can use to make a dismissal safe. It needs to be a genuine situation where the role is no longer required, and you need to follow a fair process (including consultation).

Even where redundancy is legitimate, an employer can still face an unjustified dismissal claim if the process is rushed, predetermined, or lacks meaningful consultation.

In practice, redundancy is one of the most process-heavy areas of employment law. If you’re heading toward a restructure, it’s worth getting advice early so you can manage it properly.

How To Protect Your Business From Day One (Practical Steps)

If you want to reduce dismissal risk, the goal isn’t to “lawyer up after a problem happens”. It’s to set your workplace up so issues are handled consistently and fairly from the start.

1. Use A Clear, Tailored Employment Agreement

A good agreement should clearly cover:

• notice periods and how termination works,
• pay and hours,
• confidentiality and business protections,
• trial/probation arrangements (where used), and
• key policies that apply to the role.

This is the legal foundation that prevents “wrongful dismissal” style disputes in the first place. Generic templates often miss key NZ-specific requirements or your business-specific risks.

2. Have Practical Policies And Follow Them

Policies won’t help if they’re sitting in a folder no one reads.

Make sure your team understands the basics and you apply your policies consistently. This includes expectations around conduct, performance management, investigations, and how workplace issues are raised and handled.

A workable Workplace Policy can also support procedural fairness when you need to address performance or misconduct.

3. Document Performance And Issues Early

If you’ve ever thought “I wish I wrote that down”, you’re not alone.

Good documentation doesn’t have to be complicated, but it should be consistent. You’ll usually want:

• notes of key meetings,
• written expectations and goals,
• warnings or outcome letters where relevant, and
• records of the employee’s responses and any supports offered.

This is the material that often determines whether a dismissal is seen as fair and reasonable.

4. Don’t Skip Consultation (Even When You Think The Answer Is Obvious)

In many dismissal-related situations - especially restructures - consultation is not a box-ticking exercise.

You generally need to approach the process with an open mind. If it looks like a “done deal” from the start, it can undermine the fairness of the process.

5. Get Advice Before You Terminate (Not After)

Termination is one of those steps where a quick legal check can save you a lot of time, cost, and stress.

Even if you’re confident you have a good reason, it’s worth sanity-checking:

• whether the reason is likely to be seen as justified,
• what process is appropriate in the circumstances, and
• what you need to pay (notice, leave, final pay).

If you do need to end employment, you may also need supporting paperwork. Depending on the situation, a formal exit document like a Deed of Settlement can sometimes be used to record agreed terms and reduce the risk of future disputes (but it needs to be done properly).

Key Takeaways

• Wrongful dismissal is usually about a breach of the employment agreement (for example, not giving notice or not following a contractual termination clause).
• Unfair dismissal in NZ commonly refers to a personal grievance for unjustified dismissal, which focuses on whether the dismissal was justified and whether a fair process was followed.
• A dismissal can be both wrongful and unjustified at the same time, which can increase your legal and financial exposure.
• A fair dismissal process usually involves explaining concerns clearly, giving the employee a real chance to respond, investigating where needed, and confirming decisions in writing.
• The best protection is being proactive: use a tailored Employment Contract, maintain clear workplace policies, and document issues early.
• If you’re considering termination, getting advice early can help you avoid missteps that lead to personal grievances and costly disputes.
