Can You Legally Dismiss A Pregnant Employee In New Zealand?

Finding out that an employee is pregnant is usually a positive moment for your team.

But if you’re a small business owner, it can also raise a few practical questions - especially if you’re already managing performance concerns, conduct issues, restructures, or tight cash flow.

So, can you legally dismiss a pregnant employee in New Zealand?

The short (and important) answer is: yes, sometimes - but only if the reason is lawful and the process is fair. Dismissing someone because they are pregnant (or treating them badly because of pregnancy) can quickly become a serious legal risk, including a personal grievance or a discrimination claim.

Below, we break down what the law expects from you as an employer, what situations can justify termination, and how to handle the process carefully and fairly.

Is It Illegal To Dismiss A Pregnant Employee In New Zealand?

It’s not automatically illegal to dismiss someone who happens to be pregnant. The key question is why the dismissal is happening.

In New Zealand, pregnancy is a protected ground of discrimination. This means you can’t dismiss an employee because they are pregnant, because they might take parental leave, or because pregnancy is “inconvenient” for staffing.

As a small business, it’s worth knowing the main legal frameworks that can come into play:

• Employment Relations Act 2000 - requires employers to act in good faith and follow a fair process, particularly around termination and disciplinary matters.
• Human Rights Act 1993 - prohibits discrimination in employment on grounds including sex (which includes pregnancy and childbirth).
• Parental Leave and Employment Protection Act 1987 - governs parental leave rights and protections (including protections connected to taking parental leave, and return-to-work protections in many cases).
• Holidays Act 2003 - relevant if the employee is taking sick leave, has annual leave entitlements, or you’re managing leave during a notice period.
• Health and Safety at Work Act 2015 - requires you to provide a safe workplace, which can include considering pregnancy-related risks and adjustments.

If your employee alleges they were dismissed for pregnancy-related reasons, you may need to show (with evidence) that:

• the reason for dismissal was legitimate and unrelated to pregnancy; and
• you followed a fair and reasonable process (including genuine consultation, warnings where appropriate, and an opportunity to respond).

It’s also important to remember that where an employee is taking (or is about to take) parental leave, additional protections can apply - including protections around their role being kept open in many situations, and their right to return to their job (or a similar position) depending on the circumstances.

Practically speaking, pregnancy can make dismissals higher-risk. Even if you think you have a valid reason, you’ll want to be extra careful that your documentation and process are solid.

When Can You Lawfully Dismiss A Pregnant Employee?

There are situations where it may be lawful to dismiss a pregnant employee - but the reason must be genuine, substantial, and not connected to the pregnancy. The process must also be fair.

Here are the most common lawful categories (with some practical employer-focused guidance).

1) Serious Misconduct Or Misconduct

If an employee commits misconduct (or serious misconduct), pregnancy doesn’t give them immunity from workplace rules.

That said, you still need to run a fair disciplinary process. That typically includes:

• investigating the allegations properly (don’t predetermine the outcome);
• putting the concerns in writing and giving reasonable time to respond;
• allowing a support person or representative;
• considering the employee’s explanation with an open mind; and
• only then deciding on an outcome that is proportionate (warning, final warning, dismissal, etc.).

If your business doesn’t have clear rules set out, this is where having a well-drafted Employment Contract and policies can make a real difference.

2) Ongoing Poor Performance (After Fair Support And Process)

If performance has been a long-term issue, you may be able to end employment - but you usually need to show you:

• identified clear performance expectations (and that they were reasonable);
• explained the gaps and gave examples/evidence;
• provided support, training, and a reasonable opportunity to improve;
• used a documented performance improvement process; and
• warned that employment could be at risk if improvement didn’t occur.

Pregnancy can complicate this area because symptoms (fatigue, nausea, medical appointments) may temporarily affect output. If your employee raises pregnancy-related reasons, you should genuinely consider whether adjustments are needed before escalating to termination.

A structured performance management process can help you handle this lawfully and consistently.

3) Medical Incapacity (Including If The Employee Can’t Perform The Role)

Sometimes an employee may become medically unable to perform their role, either temporarily or long-term.

Pregnancy itself is not a “medical incapacity” justifying dismissal. However, certain medical conditions or complications may mean the employee can’t safely do the work for a period of time.

In these situations, a lawful approach usually involves:

• getting appropriate medical information (with consent);
• considering temporary adjustments, alternative duties, or redeployment (where realistic);
• considering whether the inability is temporary and manageable (for example, until parental leave starts); and
• consulting with the employee before making any decision.

Be cautious about assuming what a pregnant employee can or can’t do. If you need to discuss medical information, keep it confidential and only collect what you genuinely need.

4) Genuine Redundancy (Where Pregnancy Is Not A Factor)

A redundancy can still be genuine even if an employee is pregnant - for example, if you lose a key contract, restructure the business, or need to close down a function.

But redundancies are often heavily scrutinised. If the timing lines up with a pregnancy announcement, or your communications suggest pregnancy was part of the “problem”, you may be exposed to claims that the redundancy was a pretext.

To reduce your risk, you generally need to show:

• there was a genuine business reason for the restructure/redundancy;
• you consulted in good faith before making decisions;
• you considered alternatives (redeployment, part-time arrangements, changes to duties); and
• you applied fair selection criteria (where more than one person is affected).

If redundancy is on the table, it’s worth reading up on redundancy obligations and getting advice early, before you communicate a final position to your employee.

What Employers Must Do Before Terminating (Process Matters)

Even where you have a potentially valid reason, you can still get into trouble if the process is rushed, inconsistent, or feels like a “done deal”. In New Zealand, process is not a technicality - it’s a major part of whether a dismissal is justified.

As an employer, you should aim to demonstrate that you acted as a fair and reasonable employer would in the circumstances.

While each situation is different, a fair termination process often includes:

• Clarity on the concerns: Identify exactly what the issue is (conduct, performance, restructure, etc.). Avoid vague statements like “not a culture fit”.
• Documented evidence: Keep accurate notes, emails, warnings, meeting minutes, and performance metrics.
• Notice and a chance to respond: Put concerns in writing and give the employee a genuine opportunity to respond before you decide.
• Right to support: Tell them they can bring a support person or representative to meetings.
• Good faith consultation: If there are alternatives (adjustments, redeployment, revised targets), you should consider them genuinely.
• Consistent treatment: If other staff have done similar things without being dismissed, inconsistency can work against you.

It can be tempting to “keep it informal” in a small team. But where termination is involved - especially where an employee is pregnant - a casual approach can create costly risk.

Common Traps That Lead To A Discrimination Or Personal Grievance Claim

Many employers don’t set out to discriminate. Problems often arise from rushed decisions, poor communication, or unconscious assumptions about pregnancy.

Here are some common pitfalls to avoid.

Making Decisions Based On Availability Or Future Leave

Thinking “we need someone who will be here long-term” or “parental leave will leave us short-staffed” is understandable from an operational perspective - but it’s not a lawful reason to terminate.

Instead, focus on business planning: temporary cover, fixed-term arrangements (where lawful), or redistributing duties.

Reducing Hours Or Changing Duties Without Agreement

If you’re responding to reduced capacity or a quieter period, it might feel easier to cut shifts or change hours.

But changing an employee’s hours or role without following the correct process (and without contractual authority) can lead to disputes, especially where pregnancy is involved.

If you’re considering cutting shifts, it’s worth reviewing options and risks around reducing staff hours before you take action.

Comments That Suggest Pregnancy Is “The Real Reason”

Even casual remarks can become evidence. For example:

• “This is really bad timing.”
• “We need someone reliable who won’t be away.”
• “Your role needs full energy, and you’re pregnant.”

If termination happens later, these comments can be used to argue pregnancy was a factor in the decision.

Asking Inappropriate Questions During Hiring Or Performance Discussions

If you’re hiring to replace or cover a role, be careful about questions that touch on family plans or pregnancy (even indirectly). These can cause issues under discrimination law and can also create reputational risk.

For a practical sense of what not to ask, the illegal interview questions guide is a helpful benchmark for small businesses trying to keep processes clean and compliant.

Not Handling Medical Information Properly

If pregnancy-related medical information comes up (appointments, restrictions, certificates), treat it as sensitive personal information and limit who has access.

As a general rule, only collect what you genuinely need for a lawful purpose (like managing leave, safety, or adjustments), store it securely, and keep access limited. In New Zealand, privacy obligations are commonly managed with policies and processes aligned to the Privacy Act 2020 and good HR practice.

Practical Alternatives To Dismissal (That Still Protect Your Business)

Sometimes dismissal feels like the only option - but it’s often the highest-risk path, particularly if the employee is pregnant.

Depending on what’s going on, there may be alternatives that protect your business while reducing legal exposure and disruption.

Temporary Adjustments Or Alternative Duties

If certain tasks are unsafe or unrealistic during pregnancy (for example, heavy lifting or exposure to certain hazards), consider:

• temporary task swaps;
• adjusted KPIs;
• more frequent breaks;
• hybrid work (where possible); or
• alternative duties until parental leave starts.

This is often not just “nice to do” - it can be part of your broader obligation to provide a safe workplace.

Better Planning For Leave Cover

If you’re worried about the operational impact of parental leave, plan early. Depending on your needs, you might:

• hire a fixed-term cover role (with a properly drafted agreement that clearly states it’s temporary and ends when the employee returns, or on another genuine fixed-term basis);
• redistribute duties internally;
• use contractors for short periods; or
• bring in a part-time hire to support the team.

Where you bring in someone new, make sure your paperwork is tight and your obligations are clear from day one.

Separation By Agreement (In The Right Circumstances)

In some cases, an employee may be open to a mutually agreed exit. This should be handled carefully - you don’t want an agreement that looks pressured or linked to pregnancy.

If you’re thinking about this option, it’s a good idea to get legal advice before you raise it, and to keep communications respectful and well-documented.

Handling Notice And Final Pay Correctly

If you do end up terminating (lawfully), make sure notice and final pay are handled exactly as required by the employment agreement and the law.

Some employers consider payment in lieu of notice, but you should check whether your employment agreement allows it and whether it’s appropriate in the circumstances.

Key Takeaways

• You generally can’t dismiss a pregnant employee because of pregnancy - pregnancy is a protected ground, and discrimination claims can be serious.
• You may be able to legally dismiss a pregnant employee where there is a genuine, pregnancy-unrelated reason (for example, misconduct, substantiated ongoing poor performance after support, medical incapacity with fair consultation, or genuine redundancy).
• In New Zealand, a fair process is essential. Even with a valid reason, a flawed process can make a dismissal unjustified.
• Be cautious about timing, comments, and documentation - if you’re ending employment while someone is pregnant, you should expect greater scrutiny and ensure your records clearly support the real reason.
• Consider alternatives like adjustments, redeployment, or better parental leave cover planning - these can protect your business and reduce legal risk.
• Strong foundations (clear contracts, good policies, and documented processes) make these situations much easier to manage as a small business.
