Suspension Letters in NZ: Lawful Use and Employer Actions

If you employ staff, there may come a time when you need to temporarily remove an employee from their duties while you investigate an issue.

That’s where a suspension letter comes in. Done properly, it helps you manage risk, protect people at work, and preserve a fair process.

Done badly, it can quickly turn into an expensive employment dispute (even if your underlying concerns about the employee are valid).

In this guide, we’ll walk through what a suspension letter is, when suspension is (and isn’t) appropriate in New Zealand, what you should include, and the practical steps you should follow to protect your business.

What Is A Suspension Letter (And Why Does It Matter)?

A suspension letter is a written notice to an employee that they are being temporarily removed from their duties while you deal with a workplace issue.

In most small businesses, suspension comes up during a disciplinary or investigation process - for example, where there’s an allegation of misconduct, a safety risk, or concerns about interference with an investigation.

A good suspension letter matters because it:

• Confirms the suspension in writing (so there’s a clear record of what was decided and why).
• Sets expectations (whether they’re paid, whether they can access systems, and who they can contact).
• Supports procedural fairness (which is a core requirement under NZ employment law).
• Reduces risk of misunderstandings, privacy issues, or the employee claiming they were removed from work unfairly.

In New Zealand, suspension isn’t meant to be a punishment. Think of it as a temporary risk-management tool while you work through a proper process.

Also, a suspension letter doesn’t replace your overall documentation. Your Employment Contract and your policies often determine what you can do, how you should do it, and what “process” looks like in your workplace.

When Can An Employer Suspend An Employee In New Zealand?

Suspension is a serious step. Even if you’re under pressure (for example, a complaint has been made and everyone’s emotions are running high), you still need to approach suspension carefully.

In broad terms, the law expects you to act fairly and in good faith. Under the Employment Relations Act 2000, you must maintain good faith and follow a fair process before taking action that disadvantages an employee.

Importantly, in New Zealand you should generally have a contractual basis to suspend (for example, a suspension clause in the employment agreement and/or a relevant workplace policy). If your documents are silent, suspension can be much higher risk and may only be justifiable in limited circumstances where it is necessary, reasonable, and you still follow a fair process.

Common situations where suspension may be appropriate include:

• Health and safety risk (for example, an employee’s presence could endanger others, or there are credible concerns they’re unfit for work).
• Risk to an investigation (for example, access to evidence, risk of influencing witnesses, or tampering with records).
• Serious misconduct allegations (for example, theft, violence, serious harassment, or significant breaches of trust).
• Conflict or workplace disruption that can’t reasonably be managed through other controls.

You should also keep the Health and Safety at Work Act 2015 in mind. If you have a genuine risk that needs immediate control, suspension might be one possible control measure - but you should still consider whether there are less disruptive options first.

Suspension Should Usually Be A Last Resort

Before you suspend, ask: can we manage the risk in a less extreme way?

Depending on your workplace, alternatives might include:

• temporary changes to duties or roster
• temporary relocation to another site/team
• restricted access to certain systems or areas
• working from home (if practical)
• increased supervision

If you jump straight to suspension without considering alternatives (and documenting why alternatives weren’t suitable), you may increase the risk of a personal grievance.

Is A Suspension Letter Paid Or Unpaid?

This is one of the most important practical questions for employers - and it’s also where many small businesses accidentally get into trouble.

In New Zealand, suspension is commonly paid unless:

• your employment agreement clearly allows for unpaid suspension in certain circumstances, and
• it’s lawful and reasonable to apply it in the specific situation, and
• you follow a fair process before making that decision.

Even where an agreement mentions unpaid suspension, it doesn’t automatically mean you can apply it whenever you want. You still need to consider:

• procedural fairness (did the employee have a chance to respond?)
• proportionality (is unpaid suspension justified given the risk?)
• consistency (have you treated similar situations similarly?)

Practical Tip: Treat Pay As A Default Unless You’ve Had Advice

If you’re unsure, a conservative (often safer) approach is to suspend on full pay while you investigate. It’s not always what employers want to hear, but it can significantly reduce legal risk while you work through the facts.

If you do intend to suspend without pay, it’s worth getting advice first, because the consequences of getting this wrong can be significant.

What Should You Include In A Suspension Letter?

A suspension letter should be clear, calm, and factual. Avoid emotive language, assumptions, or “verdict-style” wording.

While every situation is different, most NZ employers will want to include the following key points.

1) The Decision And The Date It Starts

• confirm the employee is suspended from duties
• state when the suspension begins (date and time)
• state whether the employee must leave the workplace immediately or finish their shift (depending on the risk)

2) Whether The Suspension Is Paid

• confirm whether the suspension is on full pay (or another arrangement)
• confirm what happens to allowances, rostered hours, commissions, etc (as relevant)
• confirm they should still record time only if required (many businesses don’t require timesheets for paid suspension, but be consistent)

3) The Reason For Suspension (Without Overstating It)

You generally need to explain why suspension is being considered/used - particularly the risk you are managing.

For example, you might refer to:

• “an allegation has been raised”
• “we need to investigate concerns about…”
• “we consider there is a risk to the integrity of the investigation if you remain at work”
• “we consider there may be a health and safety risk that needs to be managed”

Be careful not to write the letter as if you’ve already decided the employee is guilty.

4) The Process From Here (Investigation And Next Steps)

• what you will be investigating (in general terms)
• who will conduct the investigation
• expected timeframes (even if they are indicative only)
• when you will next be in touch

If the situation is part of broader performance or disciplinary management, ensure your internal steps align with your Performance Management Process (and any procedures in your employment agreement).

5) Employee Expectations While Suspended

This part of the suspension letter is often overlooked, but it’s vital for small businesses where access to clients, systems, or stock matters.

You may include requirements such as:

• not attending the workplace (unless invited)
• being available during business hours for reasonable contact
• not contacting certain colleagues or clients about the matter (where appropriate)
• confidentiality obligations
• return of keys, uniforms, vehicles, or equipment (where needed)

Confidentiality is especially important in small teams. You’re typically balancing the employee’s privacy with the business’s need to manage the workplace.

As a general rule, only share information internally on a “need to know” basis, consistent with the Privacy Act 2020. If you’re building out your internal approach to these issues, an Employee Privacy Handbook can help set clearer expectations around monitoring, investigations, and handling sensitive information.

6) Access To Support And Representation

Best practice is to remind the employee they can seek advice or bring a support person/representative to any formal meeting.

This helps demonstrate fairness and can reduce the risk of later arguments that the process was rushed or one-sided.

7) A Clear Contact Person

• name and role of who they should contact (e.g. owner/manager)
• how they should contact them (email/phone)
• boundaries (e.g. don’t message other staff about the matter)

The Right Process: Steps To Take Before And After Sending A Suspension Letter

A suspension letter is only one part of the bigger picture. What often matters most (legally) is the process you followed to get there.

Here’s a practical roadmap you can adapt to your workplace.

Step 1: Check The Employment Agreement And Your Policies

Start with what you’ve already agreed to in writing. Does the employee’s agreement allow suspension? Does it say anything about pay? Does your policy set out the procedure?

If your documentation is outdated (or silent on suspension), that doesn’t automatically mean you can suspend. In New Zealand, because suspension can be viewed as a significant step, you should treat it as higher risk without a clear contractual basis and get advice on whether it’s necessary and how to do it fairly.

Many small businesses build these expectations into a broader Workplace Policy so managers aren’t making it up on the fly when things go wrong.

Step 2: Identify The Specific Risk You’re Trying To Manage

Ask yourself: what is the risk if the employee stays at work?

• Is it a safety risk?
• Is it an evidence/investigation risk?
• Is it a serious relationship breakdown risk?

Document this internally. If the decision is challenged later, being able to show your reasoning is critical.

Step 3: Consider Alternatives (And Document Why They Won’t Work)

As mentioned earlier, suspension should typically be a last resort. If you can manage the issue with temporary changes, consider those first.

If you decide alternatives aren’t enough, note why. For example:

• the employee’s role requires system access central to the investigation
• there’s no alternative supervision available in a small team
• there’s a credible safety concern requiring immediate separation

Step 4: Give The Employee A Chance To Respond (Where Practical)

In many cases, procedural fairness means you should tell the employee you’re considering suspension and give them a chance to comment before you confirm it.

There are situations where immediate suspension may be justified (for example, urgent safety risks). Even then, you should follow up as soon as possible with written confirmation and a fair next-step process.

Step 5: Send The Suspension Letter And Control Access Sensibly

Once the decision is made, send the suspension letter promptly and keep the tone neutral.

You may also need to manage practical business steps, such as:

• disabling access to certain systems (only what’s necessary)
• changing passwords if required (do this carefully and lawfully)
• securing stock, cash, or sensitive records
• briefing managers on what they can/can’t say to the team

Avoid workplace gossip. Keep internal communications minimal and factual.

Step 6: Keep The Investigation Moving

A common mistake is suspending someone and then letting the matter drag on for weeks without updates.

Long or unexplained delays can make an otherwise reasonable suspension look unfair. Set realistic timeframes and update the employee if things change.

Step 7: Decide The Outcome And Document It Properly

After the investigation and meetings, you may decide to:

• lift the suspension and return the employee to work as normal
• return them with temporary conditions (where appropriate)
• move to a disciplinary outcome (warning, final warning, etc.)
• consider termination (in serious cases, and only after a fair process)

If matters escalate to termination, make sure your documents and steps are consistent with NZ law and your agreements. Many employers prefer to have a clear paper trail and the right letters ready, which is where an Employee Termination Documents Suite can be useful.

In some cases, you may resolve the issue by agreement (for example, with terms around confidentiality and final payments). If so, it may be appropriate to document it in a Deed of Settlement.

Common Mistakes Employers Make With Suspension Letters (And How To Avoid Them)

Suspension is one of those areas where a well-intentioned employer can still get tripped up.

Here are some common mistakes we see, especially in small businesses.

Treating Suspension As A Punishment

Language like “you are suspended for misconduct” can read like you’ve already decided the outcome. Instead, frame it around the need to investigate and manage risk.

Not Paying When You Should

Unpaid suspension is a high-risk move unless you’re confident it’s permitted and reasonable in the circumstances. If you’re unsure, get advice before you decide.

Not Being Clear About Expectations

If you don’t clearly set expectations (contact, confidentiality, access to workplace, equipment return), you may end up with:

• privacy issues
• staff conflict
• data/security risks
• claims you “changed the rules” later

Letting The Suspension Drag On

A suspension shouldn’t be indefinite. Keep the investigation moving, and communicate regularly.

Oversharing With The Team

It’s normal for staff to notice someone is suddenly away. But sharing allegations or details can create privacy and defamation risk, and it can undermine the fairness of the process.

A simple message like “X is currently away from work, and we’re managing coverage” is often enough.

Key Takeaways

• A suspension letter is a formal written notice that temporarily removes an employee from duties while you manage risk and follow a fair process.
• In New Zealand, suspension is not meant to be a punishment - it should generally be used only when necessary (and often as a last resort).
• Before suspending, you should check you have a contractual basis (usually in the employment agreement and/or policies), identify the risk, consider alternatives, and follow a procedurally fair approach consistent with good faith obligations under the Employment Relations Act 2000.
• Suspension is commonly paid unless you have a clear legal basis to suspend without pay and you’ve applied it fairly in the circumstances.
• A good suspension letter should clearly cover: pay status, reasons (without assuming guilt), expectations during suspension, confidentiality, next steps, and a contact person.
• Delays, unclear communication, and oversharing details internally are common mistakes that can increase your risk of a personal grievance.
