Gross Misconduct Investigation Questions in NZ for Employers

When something serious happens at work, it’s normal to want to act quickly. Maybe a customer complains about aggressive behaviour, money has gone missing, an employee refuses a lawful instruction, or there are allegations of bullying or harassment.

But in New Zealand, even if you think it’s “obvious” what happened, you still need to run a fair process before you decide on disciplinary action (especially dismissal). This is where asking the right gross misconduct investigation questions matters - because good questions help you gather reliable facts, test evidence, and show procedural fairness.

In this practical guide, we’ll walk you through the key investigation questions NZ employers should ask, how to structure an investigation meeting, what to avoid, and what to do after you’ve gathered the facts.

Important: This article is general information for NZ employers, not legal advice. Because “gross misconduct” situations can escalate fast, it’s usually worth getting tailored advice from an employment lawyer early - before you send a letter or hold a meeting.

What Counts As “Gross Misconduct” In NZ (And Why Definitions Matter)

In plain terms, gross misconduct is serious misconduct that can justify dismissal because it destroys trust and confidence or creates an unacceptable risk for your business, staff, customers, or property.

There isn’t one universal definition that applies to every workplace, which is why your:

• Employment Contract
• Workplace Policy

…should clearly outline examples of misconduct and gross misconduct, and what the disciplinary process looks like.

Common examples that may amount to gross misconduct (depending on context and evidence) include:

• Theft, fraud, or dishonesty (including time theft or falsifying records)
• Violence, threats, or serious aggression
• Serious bullying, harassment, or sexual harassment
• Serious health and safety breaches (especially deliberate or reckless)
• Being under the influence at work where it creates safety risk (especially in safety-sensitive roles)
• Unauthorised disclosure of confidential information or trade secrets
• Serious insubordination (refusal to follow lawful and reasonable instructions)
• Serious conflicts of interest or improper benefit

Even if the behaviour looks like gross misconduct, the outcome still depends on a fair process and whether dismissal is what a fair and reasonable employer could have done in the circumstances (this is a key theme under the Employment Relations Act 2000). In some cases, dismissal without notice may be proposed, but that will depend on the circumstances, the employment agreement, and a fair process - it shouldn’t be treated as automatic.

Before You Start: The Legal Basics That Shape Your Investigation Questions

It’s tempting to jump straight into an “interview mode” - but a gross misconduct investigation isn’t just about getting answers. It’s about gathering information fairly so you can make a defensible decision.

Before you ask investigation questions, make sure you’re covering these basics:

1) Clarify What You’re Investigating (Allegations, Not Conclusions)

Write down the allegation in neutral terms. For example:

• “It’s alleged that you removed cash from the till on [date] without authorisation.”
• “It’s alleged that you spoke to [customer/employee] in a threatening manner on [date].”

Starting with a conclusion (“you stole”, “you lied”) can look like you’ve pre-judged the outcome.

2) Gather the Evidence You Already Have

Pull together what you can before the meeting, such as:

• Rosters and timesheets
• Emails, messages, and work system logs
• Policies and relevant clauses in the employment agreement
• Customer complaint details
• Witness names
• CCTV footage (if lawfully collected and appropriate to use)

If you’re dealing with monitoring or recordings, be careful - privacy and workplace surveillance issues can be tricky, and you want to avoid creating a separate legal problem while investigating the first one. In particular, think about what notice employees have been given, whether the collection was necessary and proportionate, and how the material will be stored and shared.

3) Remember Procedural Fairness

In most cases, procedural fairness means you should:

• Tell the employee what the concerns are (and provide enough detail)
• Provide relevant information you’re relying on (where appropriate)
• Give the employee a reasonable chance to respond
• Genuinely consider their explanation before deciding outcomes
• Keep an open mind (don’t pre-determine the result)

If you’re considering dismissal, getting the process wrong can lead to costly personal grievance risk - even if the underlying allegations are serious.

Gross Misconduct Investigation Questions: What To Ask (With Practical Examples)

Effective gross misconduct investigation questions have a few things in common:

• They’re open-ended (to gather detail, not just “yes/no”)
• They focus on what happened (facts), not assumptions
• They test reliability (timelines, inconsistencies, corroboration)
• They are neutral in tone

Below are practical question sets you can adapt, depending on the allegations.

A) Foundation Questions (Set The Scene)

• Can you walk me through what happened on [date] from your perspective?
• Where were you working and what were your duties during that shift?
• Who else was working with you at the time?
• What systems or equipment were you using (till, vehicle, tools, work phone, apps)?
• Were there any unusual events that day (busy period, conflict, system outage, staffing shortage)?

B) Timeline And Detail Questions (Pin Down Facts)

• What time did the incident start and finish (as best as you can recall)?
• What happened immediately before the incident?
• What happened immediately after?
• Who did you speak to about it, and when?
• Did you write anything down or message anyone about it at the time?
• Is there anything that could help confirm your account (texts, emails, receipts, photos, screenshots)?

C) Policy And Expectation Questions (Link Conduct To Workplace Rules)

These questions help you understand whether the employee knew (or reasonably should have known) what was expected.

• Are you familiar with our policies on [cash handling / customer conduct / bullying and harassment / health and safety / confidentiality]?
• When did you last receive training or guidance on this?
• What do you understand the expected process is in this situation?
• Did you believe you were acting within policy? If yes, which part?
• Is there any reason you couldn’t comply with the policy at the time?

D) Evidence-Testing Questions (Without “Cross-Examination”)

If you have evidence that conflicts with the employee’s explanation, you can test it - but avoid turning the meeting into an interrogation.

• We have information that suggests [describe evidence neutrally]. How do you explain that?
• Is there anything you think may be missing from that information?
• Do you disagree with any part of the account provided by [witness/customer]? If so, which part and why?
• Can you think of any reason why someone might report it that way?
• Is there anyone else we should speak to who may have relevant information?

E) Intent And Context Questions (Especially For “Serious But Not Malicious” Conduct)

Sometimes the facts are clear, but the “why” matters. Intent can affect whether something is gross misconduct, misconduct, or a training/performance issue.

• What were you trying to achieve when you did/said that?
• What options did you think you had at the time?
• Did you understand there was a risk to safety, the business, or other staff?
• Were you under any pressure (time, conflict, fatigue, personal stress) that affected your judgement?
• Looking back, would you handle it differently? If so, how?

F) Questions For Specific Gross Misconduct Allegations

Here are targeted question banks you can use depending on the issue.

Theft, Cash Handling, Or Dishonesty

• Can you explain the cash handling process you followed that day?
• Did you have authorisation to remove money/stock? Who authorised it and when?
• Were any refunds, voids, discounts, or manual entries processed? Why?
• Where was the cash/stock stored and who had access?
• Are you aware of any other explanation for the discrepancy?

Bullying, Harassment, Or Inappropriate Conduct

• What exactly was said or done (your best recollection)?
• What was the tone and context of the conversation?
• Was there any prior conflict or ongoing issue between you and the other person?
• How do you think the other person may have experienced the interaction?
• Did anyone else witness the interaction or its aftermath?

Health And Safety Breaches

• What hazard were you dealing with, and what controls were in place?
• What training or instructions have you received for this task?
• Did you follow the standard process? If not, what changed and why?
• Was any PPE required, and was it used?
• Was anyone put at risk (including customers or the public)?

Intoxication Or Suspected Drug/Alcohol Use At Work

• What were your duties that day, and were they safety-sensitive?
• Did you consume any alcohol or drugs before or during work?
• Are you taking any medication that could affect performance or alertness?
• Did you feel fit for work at the start of the shift?
• Are you willing to participate in a test in line with our process? (Only do this if you have a compliant approach and documentation, such as a drug test consent form.)

Confidentiality Breaches Or Conflicts Of Interest

• What information was shared, and with whom?
• How was it shared (email, screenshot, verbal conversation, social media)?
• What was your reason for sharing it?
• Did you have permission to share it?
• Do you have any personal interest in the other business/person involved? (This often ties into a Conflict Of Interest Policy.)

G) Closing Questions (To Make Sure You’ve Been Fair)

• Is there anything else you want to add that we haven’t asked about?
• Is there any information you want us to consider before we make any decision?
• Is there anyone else you think we should speak to?
• Do you have any documents or messages you’d like to provide?
• Do you understand the next steps, and do you need time to provide a written response?

How To Run A Gross Misconduct Investigation Meeting (Without Tripping Up Your Process)

Even with the right questions, the way you run the meeting matters. A “technically correct” list of questions won’t help if the process looks rushed, biased, or unclear.

1) Invite The Employee Properly

In most cases, you should give the employee notice of the meeting, outline the allegations, and tell them they can bring a support person or representative. You should also share the key information you’re relying on (as appropriate) so they can respond meaningfully.

2) Explain The Purpose At The Start

Set expectations early. For example:

• This is an investigation meeting, not a disciplinary outcome meeting (unless you’ve clearly said otherwise).
• No decision has been made yet.
• You’re there to understand what happened and to hear their response.

3) Keep Notes (And Confirm What Will Be Recorded)

Take clear notes, including questions asked and answers given. If you plan to record the meeting, pause and get legal advice first - both consent and privacy considerations can arise, and you should be confident your approach is lawful and appropriate in the circumstances.

If the employee later asks for information you hold about them (for example, investigation notes), you may need a process to handle this under the Privacy Act 2020, and an access request form can help you manage that properly.

4) Avoid Common Mistakes That Undermine Your Investigation

• Leading questions: “You took the cash, didn’t you?” (Better: “Can you explain the cash discrepancy?”)
• Stacking allegations: keep each concern separate and clear
• Arguing: your role is to gather information, not “win” the conversation
• Surprise evidence: if you rely on something, the employee generally needs a chance to respond
• Rushing to dismissal: even serious issues often require an investigation step and a chance to respond

If you’re unsure whether you’re at “investigation” stage or “disciplinary outcome” stage, it’s usually worth getting advice before you send the next letter.

What To Do After You’ve Asked Your Investigation Questions

Once you’ve gathered responses, the next steps are about evaluating the evidence fairly and documenting your decision-making.

1) Assess The Evidence Objectively

Ask yourself:

• Do we have enough evidence to substantiate the allegations?
• Are there inconsistencies - and if so, are they material?
• Is there corroboration (documents, witnesses, system logs)?
• Have we considered alternative explanations?

2) Consider Whether It’s Truly “Gross Misconduct”

Even if an allegation is substantiated, you still need to decide whether it meets the threshold of gross misconduct in your workplace context. Consider:

• The employee’s role and level of responsibility
• Whether the conduct was deliberate, reckless, negligent, or accidental
• Potential harm (safety risk, reputational damage, financial loss)
• Whether trust and confidence has been undermined
• Any mitigating factors (training gaps, unclear instruction, personal circumstances)

3) Decide On A Fair Outcome (And Use A Proper Process)

Possible outcomes can include:

• No further action
• Training or coaching
• A formal warning
• Final warning
• Dismissal (in the most serious cases, and only after a fair process)

If termination is on the table, having the right documents and process is critical. Many businesses use an Employee Termination Documents Suite to support a compliant process (and to keep your letters and steps consistent).

4) Document The Decision

You don’t need pages of legal language, but you do want a clear file note or outcome letter that records:

• The allegations investigated
• What information was considered (and what weight you gave it)
• The employee’s response and your consideration of it
• Your findings (substantiated/not substantiated)
• The reason for the outcome
• Any expectations going forward

5) Don’t Forget Privacy And Record-Keeping

Investigation materials often include sensitive personal information. Make sure your business has a fit-for-purpose Privacy Policy and a sensible approach to:

• Who can access investigation files
• How long you keep records
• How you store them securely
• How you respond if the employee requests access to their information

Key Takeaways

• Good gross misconduct investigation questions are open, neutral, and focused on establishing facts, timelines, and context - not proving a pre-decided conclusion.
• Even if alleged conduct seems serious, NZ employers still need to follow a fair process under the Employment Relations Act 2000, including a genuine chance for the employee to respond.
• Your investigation questions should connect the alleged conduct back to workplace expectations (employment agreement terms, training, and workplace policies).
• Keep your meeting process clean: clear allegations, adequate notice, an opportunity for a support person, proper notes, and fair consideration of any explanation.
• After the investigation, document your findings and reasoning carefully - especially if you’re considering dismissal.
• Privacy matters during investigations, so store investigation records securely and be ready to handle information access requests appropriately.
