What Is Workplace Misconduct In New Zealand?

If you employ staff in New Zealand, there'll probably come a time when you need to ask: what counts as misconduct - and what do we do about it?

Misconduct issues can pop up in any business, from cafes and retail stores to tradie teams and growing startups. Sometimes it's a one-off lapse in judgement. Other times, it's repeated behaviour that's hurting your team, customers, or your bottom line.

The tricky part is that "misconduct" isn't just a label you can apply because you're frustrated - it's a workplace and legal concept that you need to handle carefully. If you don't follow a fair and reasonable process, you can end up facing a personal grievance (even where the employee's behaviour was genuinely unacceptable).

Below, we break down how to define misconduct, how it's different from serious misconduct, and how to manage it in a way that protects your business and treats people fairly.

What Is Misconduct (And Why Does It Matter For Employers)?

In simple terms, misconduct is behaviour by an employee that breaches workplace expectations - for example, your policies, instructions, standards of behaviour, or obligations in their role.

When employers ask what misconduct is, they're usually trying to work out two things:

• How serious is the behaviour?
• What process do we need to follow to address it?

In New Zealand, misconduct matters because disciplinary action (including warnings and dismissal) has to be both substantively justified and procedurally fair. That comes from the general principles under the Employment Relations Act 2000, including the requirement of good faith in employment relationships.

Even if you feel the situation is "obvious", you still need to:

• investigate properly
• put concerns to the employee
• give them a genuine chance to respond
• consider their explanation with an open mind

This is also why it's worth having a clear Employment Contract and well-drafted policies from day one - it's much easier to manage issues when expectations are written down.

Common Examples Of Misconduct In The Workplace

Misconduct can look very different depending on your industry and the employee's responsibilities. What matters is whether the behaviour breaches a reasonable workplace expectation.

Here are common examples we see for small businesses:

Performance And Behaviour Issues

• repeated lateness or unexplained absences
• failing to follow reasonable instructions
• poor conduct towards customers (rudeness, arguing, aggressive communication)
• failure to meet reasonable standards after training/support

Note: not all performance problems are "misconduct" - some are capability issues. That's where a clear performance management process can help you separate "can't do the job" from "won't do the job".

Policy Breaches

• misuse of company property (vehicles, tools, equipment, devices)
• breach of health and safety rules (especially under the Health and Safety at Work Act 2015)
• inappropriate use of email, messaging platforms, or systems
• breaches of confidentiality or privacy expectations

If you monitor or investigate using workplace tech (like CCTV or device logs), keep privacy front of mind. For example, cameras may be lawful in some circumstances, but they need to be used and managed properly - and employees should generally know they're being monitored. The rules around workplace cameras can catch employers out if handled poorly.

Dishonesty And Conduct That Undermines Trust

• timesheet fraud or inaccurate time records
• falsifying receipts or expense claims
• unauthorised discounts or "mates rates" for customers
• taking stock or cash (even small amounts)

Dishonesty is often treated more seriously because it goes to trust and confidence - which is central to the employment relationship.

Social Media And Reputation Issues

• posting abusive content about the business or customers
• sharing confidential workplace information online
• online behaviour that impacts workplace relationships or your brand

These issues are increasingly common - particularly where the employee identifies themselves as working for your business. If you're building or updating your policies, a clear reference point is an employee social media use policy/approach.

Misconduct vs Serious Misconduct: What's The Difference?

A big part of defining misconduct for employers is understanding where the line is between misconduct and serious misconduct.

Generally:

• Misconduct is unacceptable behaviour that may justify disciplinary action such as a warning (and potentially termination if repeated and managed fairly over time).
• Serious misconduct is behaviour so serious that it may justify dismissal (including, in some cases, summary dismissal), but this will still depend on the circumstances, your employment agreement, and following a fair process.

There's no single universal definition that applies in every workplace. What counts as serious misconduct depends on factors like:

• the employee's role and level of responsibility
• the risk caused (to safety, customers, money, reputation)
• whether there was intent (deliberate vs careless)
• whether the behaviour is a one-off or part of a pattern
• your documented policies and past practice

Examples Of Serious Misconduct (Often Seen In NZ Workplaces)

• theft or fraud
• serious breach of health and safety putting others at risk
• violence, threats, or bullying/harassment
• serious insubordination (refusing lawful and reasonable instructions)
• serious dishonesty (including lying in an investigation)
• working under the influence of drugs/alcohol where safety is at risk

Even if something "looks" like serious misconduct, it's still risky to jump straight to dismissal. A common employer mistake is treating an allegation as fact before investigating it.

How Should Employers Handle Misconduct Allegations? (A Practical Process)

Once you've identified possible misconduct, your next question is usually: "What do we do now?"

In New Zealand, the safest approach is to run a structured disciplinary process that is fair and well-documented. Here's a practical framework that works for many small businesses.

1) Check Your Employment Agreement And Policies

Start by confirming what your workplace documents say the expectations are.

• What does the employment agreement say about conduct and disciplinary procedures?
• Do you have relevant policies (e.g. code of conduct, social media, health and safety, conflicts of interest)?

For example, if the issue involves an employee not disclosing a side business, gifts, or relationships, having a Conflict Of Interest Policy can make expectations much clearer.

2) Investigate First (Don't Pre-Judge)

You don't need to run a "courtroom-style" investigation - but you do need to take reasonable steps to find out what happened. That might include:

• speaking with witnesses
• reviewing rosters, CCTV footage (if applicable), messages, or system logs
• collecting relevant documents (receipts, incident reports, customer complaints)

Be careful with privacy and proportionality, especially when collecting personal information. The Privacy Act 2020 requires you to collect and use personal information in a lawful and fair way, and only where it's reasonably necessary.

3) Put The Allegations To The Employee In Writing

Before you make a decision, you need to clearly explain:

• what the allegations are
• what information you've relied on so far
• what the potential consequences could be (e.g. a warning or dismissal)

Invite the employee to a meeting and give them reasonable time to prepare. You should also let them know they can bring a support person or representative.

4) Hold A Disciplinary Meeting And Genuinely Consider Their Response

At the meeting:

• walk through the concerns calmly and clearly
• let them respond without interruptions
• ask questions to clarify, not to "trap" them

After the meeting, take time to consider what they've said. If new information comes up, you may need to investigate further or hold a follow-up meeting.

5) Decide On An Outcome That Matches The Situation

Possible outcomes might include:

• no action (if allegations aren't proven)
• informal counselling/coaching
• a formal warning (first/final warning)
• training or closer supervision
• termination (usually for serious misconduct, or repeated misconduct after warnings)

If you are considering dismissal, it's a good idea to get advice before you move forward - termination is one of the highest-risk decisions an employer can make. Even where misconduct is clear, process errors can still create liability. In many cases, employers also need to consider notice, final pay, and whether payment in lieu of notice applies under the contract and circumstances.

6) Confirm The Decision In Writing

Your decision letter should usually cover:

• the findings (what you consider proven)
• the reasons for your decision
• the outcome (warning / dismissal / other)
• what improvement is expected (if relevant) and what happens if it doesn't occur
• the right to raise a personal grievance

This paper trail is important. It demonstrates fairness, helps avoid misunderstandings, and protects your business if the decision is later challenged.

Common Employer Mistakes (And How To Avoid Them)

Most employers aren't trying to "do the wrong thing" - misconduct issues are stressful, time-sensitive, and often emotionally charged.

Here are some of the most common pitfalls we see, and how you can avoid them.

Moving Too Quickly To Dismissal

If you assume something is serious misconduct without properly testing the facts, you can end up with an unjustified dismissal claim. Even where you're confident you're right, the process still matters.

If dismissal is on the table, it's worth getting guidance early - including on the steps involved in how to terminate an employee lawfully in New Zealand.

Not Separating Misconduct From Medical Or Wellbeing Issues

Sometimes behaviour issues overlap with wellbeing - for example, irritability, absence, or disengagement. You can still manage misconduct, but you should be careful not to treat genuine health matters as "bad behaviour".

As a general point, employees may be able to use sick leave where they're unwell (including for mental health). If this is relevant in your workplace, it helps to understand how mental health days can fit within sick leave settings, and how to approach conversations supportively while still managing performance expectations.

Inconsistent Treatment Between Staff

If two employees do the same thing but only one is disciplined, you may create a fairness issue (and a workplace culture issue). Consistency doesn't mean identical outcomes every time - but you should be able to explain why one situation was different (e.g. different role, different risk, different history).

Relying On Vague Policies Or Verbal "Rules"

Many disputes come down to one problem: the business never clearly documented expectations.

Even a simple set of policies and a well-drafted employment agreement can reduce grey areas and help you act confidently when issues arise.

Forgetting About Confidentiality And Privacy During The Process

Misconduct investigations often involve sensitive information. Limit discussions to those who genuinely need to know, store documents securely, and avoid "workplace gossip" becoming part of the problem.

If you collect customer complaints, CCTV footage, messages, or witness statements, make sure you handle that information in a way that aligns with privacy obligations.

Key Takeaways

• What is misconduct? It's behaviour that breaches reasonable workplace expectations, policies, instructions, or obligations.
• Misconduct is different from serious misconduct - serious misconduct may justify dismissal in some cases, but you still need to follow a fair process and check what the employment agreement requires (including around notice).
• A lawful process usually involves investigating, putting allegations in writing, holding a meeting, genuinely considering the response, and confirming the outcome in writing.
• Small business employers commonly run into trouble by moving too quickly, failing to document expectations, or treating different staff inconsistently.
• Having clear workplace foundations - like a strong employment agreement and practical policies - makes misconduct issues far easier to manage and reduces legal risk.
• If you're unsure whether behaviour is misconduct or serious misconduct, or you're considering termination, it's worth getting tailored advice before you act.
