Personal Grievances In New Zealand: What Employers Should Know

If you employ staff in New Zealand, there’s a good chance you’ll hear the term personal grievance at some point - and it can feel intimidating if you’re not dealing with this stuff every day.

The good news is that most personal grievance issues are preventable (or at least manageable) when you have the right foundations in place. That means clear expectations, fair processes, and employment documents that actually match how your business operates.

In this guide, we’ll break down what a personal grievance is in NZ, when it can arise, the practical steps you can take to reduce your risk, and what to do if an employee raises a personal grievance against your business.

This article provides general information only and does not constitute legal advice. If you need advice about your specific situation, it’s best to get tailored guidance.

What Is A Personal Grievance In NZ?

A personal grievance is a formal employment complaint an employee can raise when they believe an employer has treated them unfairly in certain legally recognised ways.

In New Zealand, personal grievances sit under the Employment Relations Act 2000. They’re one of the main pathways employees use to challenge an employer’s decisions, especially around discipline, performance management, workplace conflict, and termination.

From an employer’s perspective, the most important thing to understand is this: a personal grievance is often less about whether your decision was “right” in a business sense, and more about whether you acted as a fair and reasonable employer would in the circumstances - including by following a proper process.

Common Grounds For A Personal Grievance

An employee may be able to raise a personal grievance if they believe they’ve experienced one of the following:

• Unjustified dismissal (including constructive dismissal, where an employee claims they were forced to resign).
• Unjustified disadvantage (for example, being treated unfairly compared to others, or having hours changed without proper consultation when their agreement doesn’t allow it).
• Discrimination (for example, based on sex, race, age, disability, religion, family status - typically linked to protections under the Human Rights Act 1993).
• Sexual harassment or racial harassment.
• Duress relating to membership (or non-membership) of a union.

Even if you think you’ve acted reasonably, a personal grievance can still be raised if the employee believes the process was rushed, unclear, biased, or not properly documented.

Is A “Complaint” The Same As A Personal Grievance?

Not always. Many workplace issues start as informal complaints (for example, a staff member saying they’re unhappy with a roster or manager). But if the issue falls within the legal grounds above, and the employee decides to formalise it, it can become a personal grievance.

This is why having clear communication and a consistent approach to workplace issues matters - it’s often the difference between resolving something early and dealing with a formal dispute later.

When Can An Employee Raise A Personal Grievance?

Timing matters a lot with personal grievances in NZ.

The 90-Day Time Limit

In most cases, an employee must raise a personal grievance with you within 90 days of the action happening or, in many situations, within 90 days of when the employee became aware of it (or ought reasonably to have become aware of it).

That said, there are situations where the time limit may be extended (for example, if the employee can show exceptional circumstances). So as an employer, it’s best not to rely on the 90-day rule as a “safety net”. If an issue is brewing, treat it seriously and early.

Do Employees Need To Put It In Writing?

A personal grievance doesn’t always need to start as a formal letter. The key is whether the employee has clearly communicated that they are raising a grievance about a specific issue (and that it is being raised as a personal grievance).

Practically, though, once you become aware an employee is raising a personal grievance, you should:

• ask them to confirm the details in writing (what happened, when, and what outcome they’re seeking), and
• respond in writing acknowledging you’ve received it and outlining next steps.

This helps keep things clear and reduces the risk of misunderstandings later.

Why Personal Grievances Are A Big Risk For Small Businesses

Personal grievance claims can be time-consuming, stressful, and expensive - especially for small business owners who are already juggling operations, cashflow, and staffing.

Common pressure points we see for small businesses include:

• Wearing multiple hats (the owner is also the manager, HR, and payroll).
• Informal processes (quick chats instead of documented meetings).
• “Handshake” arrangements that aren’t reflected in a written agreement.
• Performance issues being dealt with too late - then escalated quickly.
• Termination decisions being made under pressure without a proper process.

It’s also worth remembering: even when you do everything right, an employee can still raise a personal grievance. The goal isn’t to eliminate all risk (no one can do that), but to put your business in the strongest position to resolve issues early and demonstrate you acted fairly and lawfully.

How Can Employers Reduce The Risk Of A Personal Grievance?

If you want to reduce personal grievance risk, focus on two things:

• Strong legal foundations (clear agreements and policies), and
• Fair process (especially when issues arise).

1. Use A Clear, Up-To-Date Employment Agreement

Your employment agreement is where expectations, hours, duties, notice periods, and disciplinary processes often start.

If you’re relying on a generic template (or an agreement that hasn’t been updated in years), you may find it doesn’t reflect your real-world arrangements - and that gap can cause disputes.

Having a properly drafted Employment Contract helps you set expectations from day one and gives you a clearer framework to rely on if things go wrong.

2. Set Workplace Policies That Match How You Operate

Workplace policies aren’t just paperwork - they’re part of how you show your business takes fairness and safety seriously.

Common policies that can help prevent issues escalating into a personal grievance include:

• Code of conduct and behaviour expectations
• Bullying and harassment policy
• Disciplinary and performance management procedures
• Leave and attendance expectations
• Health and safety processes (aligned with the Health and Safety at Work Act 2015)

If you don’t have these in place, or they’re inconsistent, it becomes much harder to show you treated someone fairly and consistently. A tailored Workplace Policy suite can make a big difference here.

3. Handle Performance Issues Early (And Document Them)

One of the most common pathways into a personal grievance is a performance issue that drags on quietly, then suddenly ends in a disciplinary meeting or dismissal.

Instead, aim for a stepped approach:

• Set clear role expectations and measurable standards
• Give early feedback (with examples)
• Offer support and training where appropriate
• Keep written notes of key conversations and agreed actions

If you need to move into a more formal process, you’ll want that process to be fair, well-structured, and properly recorded. Many employers get support here through a performance management process that is consistent and legally defensible.

4. Be Careful With Privacy And Employee Information

Personal grievances sometimes involve allegations about how information was handled - for example, sensitive details being shared inappropriately, CCTV use, monitoring concerns, or mishandling complaints.

In New Zealand, the Privacy Act 2020 sets rules around collecting, using, storing, and disclosing personal information. Even a well-intentioned message to “explain what’s happening to the team” can create risk if it discloses too much about an employee.

Having an Employee Privacy Handbook can help you set clear boundaries around workplace privacy (and train managers on what not to do).

5. Consult Properly Before Making Big Changes

Changes to hours, duties, reporting lines, or workplace structure can easily lead to claims of unjustified disadvantage if they’re done abruptly or without consultation.

This is especially important if you’re considering a restructure or redundancy. Redundancy situations can carry personal grievance risk if consultation is rushed or the process isn’t genuine, even where the business reasons are real.

If that’s on your radar, getting advice early through Redundancy Advice can save you headaches later.

What Should You Do If An Employee Raises A Personal Grievance?

If you receive a personal grievance, don’t panic - but do move carefully. The way you respond early can significantly affect whether the matter resolves quickly or escalates.

Step 1: Acknowledge It Promptly (In Writing)

Reply to the employee to confirm you’ve received their grievance. Keep it professional and neutral. Avoid debating the facts in your first response - you’re acknowledging receipt, not arguing your case.

It’s often helpful to confirm:

• you will look into the concerns raised
• the process you propose (for example, an investigation meeting)
• expected timeframes (where possible)
• that they can bring a support person/representative to any meeting

Step 2: Preserve Documents And Keep Communications Tight

As soon as a grievance is raised, assume anything you write could be reviewed later in mediation or the Employment Relations Authority (ERA).

Practical tips:

• Keep notes of key events, meetings, and decisions.
• Keep communications factual and respectful.
• Limit discussions to people who genuinely need to know.
• Don’t delete messages or records - keep them organised.

Step 3: Investigate Fairly

A fair investigation generally means:

• you approach the issue with an open mind
• you give the employee a genuine opportunity to explain their side
• you consider relevant information (including witness accounts where appropriate)
• you avoid predetermining the outcome

Even if you’re confident you’ve acted appropriately, a “tick-the-box” investigation (or no investigation at all) is a common reason employers get into trouble.

Step 4: Consider Early Resolution (Without Admitting Liability)

Many personal grievances settle through discussion or mediation. Settlement isn’t necessarily an admission you did something wrong - often it’s a commercial decision to reduce distraction and move forward.

Common resolution options may include:

• an apology or clarification
• changes to work arrangements
• training or management coaching
• compensation (in some cases)
• an agreed exit and settlement

If you’re considering an exit pathway, it’s important to get the paperwork right. A poorly handled termination (even where the working relationship has broken down) is one of the fastest ways a personal grievance escalates.

Where you’re moving toward ending employment, using an Employee Termination Documents Suite can help ensure the process and documents are consistent and legally sound.

Step 5: Know Where It Can Go Next (Mediation, ERA, Employment Court)

If you can’t resolve things directly, the next steps often involve:

• Mediation (often through MBIE mediation services)
• Employment Relations Authority (ERA) involvement for investigation and determination
• Employment Court (usually for more complex litigation or appeals)

At each stage, the focus tends to come back to whether you acted as a fair and reasonable employer would in the circumstances.

What Outcomes Can A Personal Grievance Lead To?

The outcomes depend on the type of grievance and what the decision-maker finds, but can include:

• reinstatement (often considered first, where practicable and reasonable)
• lost wages (which may be reimbursed, commonly up to a specified cap unless an exception applies)
• compensation for humiliation, loss of dignity, and injury to feelings
• orders to take certain steps (for example, to address the disadvantage) and, in some cases, penalties where there has been a breach of employment obligations
• costs and significant time spent dealing with the process

That’s why it’s so important to treat a personal grievance as both a legal issue and a business risk issue - you want to protect your team, your time, and your reputation.

Key Takeaways

• A personal grievance is a formal workplace complaint under the Employment Relations Act 2000, commonly raised for unjustified dismissal, unjustified disadvantage, discrimination, or harassment.
• Most personal grievances come down to whether you acted fairly and followed a proper process - even a reasonable business decision can create risk if it’s handled unfairly or without proper documentation.
• Employees generally must raise a personal grievance within 90 days, but employers should still treat issues seriously even if timing is unclear (and extensions can apply in limited cases).
• You can reduce risk by having a clear Employment Contract, consistent policies, good performance management practices, and careful handling of employee information under the Privacy Act 2020.
• If a personal grievance is raised, respond promptly, investigate fairly, keep communications professional, and consider early resolution before things escalate.
• For restructures and exits, get advice early - these are high-risk areas for personal grievances if consultation or documentation is rushed.
