Standing Down An Employee Pending Investigation in NZ

When something serious happens at work, your first instinct might be to “stand the employee down” while you work out what’s going on. For small businesses, it can feel like the only practical option - especially if you’re worried about safety, misconduct, or the integrity of your investigation.

But in New Zealand, standing down an employee pending investigation isn’t something you can do casually. If you handle it poorly, you can unintentionally create a personal grievance risk (even if your underlying concerns were completely valid).

In this guide, we’ll walk through what a stand down (often described in NZ as a “suspension”) actually means, when it may be appropriate, and how to do it in a fair, lawful, and low-risk way.

This article is general information only and isn’t legal advice. If you’re dealing with a live situation, it’s worth getting advice tailored to your facts.

What Does “Standing Down Pending Investigation” Mean In NZ?

In everyday business language, “standing down” usually means temporarily removing an employee from the workplace while you investigate allegations or concerns.

In NZ employment law, the closest concept is usually a suspension (or, in some cases, a period of agreed paid leave), meaning:

the employee is still employed (their employment hasn’t been terminated),
they are not required (or allowed) to perform work during the period, and
you are managing an interim risk while you investigate and consider outcomes.

A stand down is not a “finding” of wrongdoing. It’s a temporary step taken while you gather facts and follow a process.

Is It Paid Or Unpaid?

This is a key risk area for employers. In many situations, a stand down should be on full pay - particularly where you are directing the employee not to work while you look into concerns.

An unpaid suspension is generally higher risk and is usually only considered where there is a clear contractual basis (and the employer has acted fairly and reasonably in the circumstances). If you direct an employee not to work and then stop paying them without a solid legal basis, you could face claims around wage arrears and unjustified disadvantage.

This is also why it’s worth having properly drafted documents in place from day one, including a clear Employment Contract that addresses suspension/stand down rights and processes.

When Can You Stand Down An Employee Pending Investigation?

There isn’t a single “one size fits all” rule. Whether standing down an employee pending investigation is appropriate will depend on your reasons, what your employment agreement says, and whether it’s a reasonable step in the circumstances.

In NZ, employers generally need to act consistently with:

good faith obligations under the Employment Relations Act 2000,
procedural fairness (natural justice), and
the requirement to act as a fair and reasonable employer would in the situation.

Common Situations Where A Stand Down May Be Reasonable

Standing down may be appropriate where keeping the employee at work would create a real risk, such as:

Health and safety risk: for example, violent behaviour, threats, serious impairment, or safety-critical roles where risk needs to be controlled immediately.
Risk to the integrity of the investigation: for example, concerns they may interfere with evidence, influence witnesses, or delete records.
Allegations of serious misconduct: theft, fraud, harassment, assault, serious policy breaches.
Client/customer risk: where the employee’s continued presence could expose clients, customers, or the public to harm or significant risk.
Workplace breakdown: where relationships have deteriorated to a point that ongoing attendance could escalate the situation.

When A Stand Down Is More Likely To Be Risky

A stand down may be difficult to justify if:

you’re using it as a “cooling off” tool when there are other workable options,
your concerns are minor or vague and you haven’t identified a real risk,
you haven’t given the employee a chance to respond before removing them from the workplace (where it’s reasonable to do so), or
you treat suspension as a punishment rather than a neutral interim step.

If your decision is challenged later, the question often becomes: was suspension necessary, and did you consider alternatives?

How To Stand Down An Employee Pending Investigation (Step-By-Step)

If you’re going to stand down an employee pending investigation, the process matters as much as the reason. Even if you end up substantiating concerns, a flawed process can still create liability.

1. Get Clear On The Risk You’re Trying To Manage

Before you do anything, identify what risk exists right now. For example:

Is anyone unsafe?
Could evidence be destroyed?
Are customers at risk?
Could the situation escalate if the employee remains onsite?

This helps you decide whether suspension is genuinely necessary, and it helps you document your reasoning.

2. Check Your Employment Agreement And Policies

Your starting point is always the employment agreement and workplace policies. Some agreements contain a suspension clause that sets out when suspension can happen, whether it is paid, and the process required.

If your agreement doesn’t include a clear right to suspend, you should be cautious about imposing a suspension unilaterally. In many cases, employers instead propose a temporary period of paid leave (by agreement) or use other risk controls while the investigation runs.

If you don’t have clear written policies, it’s harder to show consistency and fairness. Many small businesses build these rules into a Workplace Policy (or broader handbook) so managers aren’t making it up as they go.

3. Consider Alternatives To Suspension

Before you suspend, consider whether there’s a less disruptive way to manage the risk, such as:

temporary alternative duties (e.g. admin tasks instead of customer-facing work),
temporary reassignment to another site or team,
working from home (if practical),
adjusted supervision or restricted system access,
staggered shifts to separate employees while interviews happen.

You don’t have to pick an alternative if it doesn’t manage the risk - but you should be able to show you turned your mind to it.

4. Invite The Employee To A Meeting (If Possible) And Explain The Proposal

Unless the situation is genuinely urgent (e.g. immediate safety concerns), it’s generally safer to tell the employee you are considering suspension and give them a chance to respond.

In practice, that often looks like:

inviting them to a meeting,
explaining the allegations/concerns at a high level (without “trying the case” on the spot),
explaining why you’re considering suspension, and
giving them an opportunity to comment (and bring a support person).

This step is about fairness. It also protects you if the employee later claims you’d already made up your mind.

5. Confirm The Stand Down In Writing

If you decide to proceed, confirm it in writing. Your letter should be calm, factual, and clear. It should usually cover:

that the suspension/stand down is pending investigation (not disciplinary action),
the reason for the stand down (risk-based and specific, not emotive),
whether the stand down is paid,
expected duration (or when you’ll next review it),
confidentiality expectations,
rules about workplace attendance and contacting staff/clients, and
who the employee can contact with questions.

It’s also smart to align your documentation with your broader investigation and disciplinary process. If you’re unsure, having a lawyer help you structure your documents early can reduce the risk of process issues later - for example via an Employee Termination Documents Suite (even if you’re not at termination stage yet, the underlying process documents and letters matter).

Running A Fair Investigation While The Employee Is Stood Down

A stand down isn’t a “pause button” that lets the investigation drag on. Once you remove someone from work, you should move the investigation along promptly and fairly.

Keep The Investigation Tight And Objective

As a general rule:

collect evidence (documents, CCTV where lawful, system logs, messages),
interview relevant witnesses,
put allegations to the employee clearly, and
give them a genuine opportunity to respond before decisions are made.

For many small businesses, it helps to map this against a consistent disciplinary approach, like the kind used in a Performance Management Process, even where the issue is misconduct rather than capability.

Manage Privacy And Confidentiality Carefully

Investigations can easily cross into privacy issues - especially if you’re collecting statements, searching work devices, reviewing emails, or dealing with sensitive allegations.

Be careful about:

only collecting information you genuinely need,
limiting who has access to investigation materials,
avoiding workplace gossip (to protect everyone involved), and
storing records securely.

If you haven’t already, it’s worth tightening up your internal rules around monitoring, access to information, and investigation confidentiality in an Employee Privacy Handbook.

If Drug Or Alcohol Testing Is Involved

Some investigations involve suspected impairment, especially in safety-sensitive workplaces. Drug/alcohol testing is a specialist area and needs to be done carefully and consistently, usually under a clear workplace policy and with proper consent procedures.

If testing may be part of your process, using a fit-for-purpose Drug Test Consent Form can help you handle consent and privacy properly (and avoid ad-hoc approaches that create risk).

Common Mistakes Employers Make (And How To Avoid Them)

Even well-meaning employers can fall into traps when standing down an employee pending investigation - especially when emotions are running high.

Mistake 1: Treating The Stand Down Like A Punishment

If your communication suggests the employee is “guilty” before the investigation is complete, you increase the chance of a grievance for unjustified disadvantage.

Fix: Keep wording neutral, and frame suspension as a temporary, risk-management step.

Mistake 2: Suspending Without Pay (Without A Clear Basis)

Directing someone not to work and then not paying them is a common flashpoint.

Fix: Check the employment agreement, act reasonably, and get advice if you’re considering unpaid suspension.

Mistake 3: Letting The Investigation Drag On

A long stand down (especially with minimal updates) can look like you’re sidelining the employee rather than investigating.

Fix: Set timelines, update the employee, and review whether continued suspension is still necessary.

Mistake 4: Not Considering Alternatives

If the employee could have been safely redeployed or restricted, suspension might be seen as disproportionate.

Fix: Document the alternatives you considered and why they weren’t workable.

Mistake 5: Poor Documentation

If it’s not written down, it’s much harder to prove later that you acted fairly and reasonably.

Fix: Confirm key steps in writing (meeting invite, suspension letter, allegation letter, outcome letter), and keep a clear file note of your reasoning.

Key Takeaways

In NZ, “standing down an employee pending investigation” is usually treated as a suspension (or sometimes agreed paid leave), and it should be handled as a neutral, temporary step - not a punishment.
A stand down is most defensible where there’s a genuine risk (health and safety, interference with evidence, serious misconduct, or workplace breakdown).
In many cases, the safest approach is a paid stand down; unpaid suspension is generally higher risk and should only be considered with a clear contractual and legal basis.
Before suspending, you should consider practical alternatives like adjusted duties, restricted access, or working from home.
Your process matters: communicate clearly, give the employee an opportunity to respond (where reasonable), confirm everything in writing, and run the investigation promptly.
Privacy and confidentiality are crucial during investigations - especially when collecting statements or reviewing work communications and records.
If you’re unsure, getting advice early can prevent a process issue turning into a personal grievance later.
