Consulting Employees And Unions In New Zealand: When It’s Required

If you employ people in New Zealand, “consultation” isn’t just a nice-to-have. In many common situations (like changing hours, restructuring roles, or introducing new policies), consulting properly is often an important practical step - and in some cases it will be required under an employment agreement, a collective agreement, or to meet your good faith obligations.

This guide explains what consultation with employees in New Zealand really means, when you’ll usually need to do it (including where unions are involved), and how to run a consultation process that’s fair, efficient, and aligned with your obligations as an employer.

What Does “Consultation” Mean In New Zealand Employment Law?

In everyday business terms, consultation means:

• you tell people what you’re proposing (before you finalise the decision),
• you give them a genuine chance to respond (including time and information), and
• you genuinely consider what they say before making your final decision.

In New Zealand, consultation often sits inside a bigger legal concept: good faith under the Employment Relations Act 2000. Good faith isn’t just “being polite”. It includes obligations to be communicative, responsive, and not misleading.

So, if you’re thinking about a change that affects your employees, “we’ve decided and we’re just letting you know” is usually not consultation. Even if your reasons are solid, skipping the process can create problems later (including personal grievances).

Consultation vs Notification: The Practical Difference

A common mistake we see in small businesses is treating consultation like an announcement.

• Notification is: “Here’s what’s happening next week.”
• Consultation is: “Here’s what we’re considering and why. Tell us what you think, and we’ll take it into account before deciding.”

You don’t have to agree with every piece of feedback, and you don’t have to keep the business exactly the same. But you do need to run a process that’s real (and that looks real on paper).

Why “Process” Matters As Much As The Outcome

From a risk perspective, many employment disputes aren’t really about whether the business had a reason to change something. They’re about whether the employer:

• gave employees enough information,
• gave them enough time to respond,
• approached the process with an open mind, and
• followed their Employment Contract and any workplace policies.

If you’re aiming to improve how you manage consultation with employees in New Zealand, start by treating consultation as a business process (not a conversation you “squeeze in” at the end).

When Is Employee Consultation Required In New Zealand?

There isn’t a single rule that says “you must consult in every situation”. Whether consultation is required (and what it needs to look like) will depend on things like:

• your good faith obligations,
• the terms of the employee’s individual employment agreement,
• any applicable collective agreement, and
• the nature and impact of the change you’re proposing.

That said, there are several common scenarios where consultation is either required by the applicable documents, or strongly expected as part of acting in good faith (especially where a decision may negatively affect employees).

Here are some of the most common situations where consultation with employees in New Zealand becomes essential for employers.

1) Restructures And Redundancy

If you’re considering a restructure that may disestablish roles, reduce headcount, or significantly change job duties, you generally need a fair process. That usually includes:

• sharing a proposal (not a final decision),
• explaining the business reasons,
• providing relevant information employees need to respond,
• giving employees a reasonable opportunity to give feedback, and
• considering feedback before finalising the outcome.

Redundancy processes are a major area where employers get caught out, especially when time pressures are high. If redundancy is on the table, it’s worth getting advice early so you don’t accidentally run an “outcome-first” process. Many employers also benefit from tailored support like Redundancy Advice to ensure the steps, documents, and timelines are defensible.

You can also read our overview on redundancy to understand what a fair process typically involves.

2) Changing Hours, Rosters, Or Reducing Staff Hours

Small businesses often need to adjust hours due to seasonality, reduced revenue, or operational changes. But if an employee’s hours are a term of their employment (which they usually are), you generally can’t just reduce them unilaterally.

A change to hours commonly requires:

• checking the employment agreement and any flexibility clauses,
• consulting about the proposed change, and
• getting agreement to vary the terms (or following a lawful process if agreement isn’t reached).

If you’re considering cutting shifts, it’s important to approach it as a consultation process rather than a roster update. Our guide on reducing staff hours is a helpful starting point.

3) Stand-Downs Or Temporary Closures

In difficult circumstances (like sudden loss of work, supply issues, or premises problems), employers sometimes consider “standing down” employees. Whether you can do this, and how you do it lawfully, depends on your agreements and the circumstances.

Even where a stand-down may be an option, you should still expect to consult and communicate clearly about:

• what the issue is,
• how long the stand-down might last (if known),
• what options exist (alternative duties, working from home, annual leave by agreement, etc.), and
• how employees can provide input.

For more context, see our guide on employee stand down.

4) Major Changes To Duties, Reporting Lines, Or Location

Even if you’re not making redundancies, you may still need consultation if you’re proposing changes that materially affect an employee’s role, such as:

• removing key responsibilities,
• introducing significantly different tasks,
• changing who they report to (where it meaningfully changes the role), or
• moving their work location (especially if travel time/cost changes).

As a rule of thumb: if the change impacts what the employee was hired to do, or how they do it, treat it as a consultation topic.

5) Introducing Or Updating Workplace Policies

Policies are one of the easiest ways to prevent confusion and set expectations. But if you introduce or materially change policies that affect how employees work (for example, privacy, monitoring, social media, performance expectations, flexible work, etc.), consultation can help you:

• identify issues you might have missed,
• increase buy-in and compliance, and
• reduce arguments later about whether a policy is fair or workable.

For many small businesses, having a clear Workplace Policy framework (and rolling changes out properly) makes day-to-day management much smoother.

Consulting Unions: When Do You Need To Involve A Union?

Union involvement is one area where employers can feel unsure, particularly if you haven’t worked with unions before. The key point is this: if an employee is a union member (or covered by a collective agreement), union rights may be triggered depending on what’s happening.

In New Zealand, unions commonly come into play in two broad ways:

• Collective bargaining and collective agreements (where a union negotiates terms for covered employees).
• Representation (where an employee chooses a union representative to support them in discussions, meetings, or disputes).

Employees Can Choose Representation

If an employee asks for a representative (including a union representative) during consultation meetings, you should generally allow that, as long as it’s reasonable and the process stays constructive.

From a practical standpoint, allowing representation often helps keep conversations clear and reduces the risk of misunderstandings later.

Collective Agreements Can Add Extra Rules

If your workplace has a collective agreement, it may have specific requirements around:

• how change processes work,
• what information must be provided,
• timelines for consultation, and
• redeployment or redundancy steps.

That means consultation isn’t “one-size-fits-all”. The right process can depend on the employment agreement(s) in place.

Good Faith Still Applies

Even when you’re consulting with union involvement, the core principles are the same: be upfront, share what you can, give reasonable time for feedback, and genuinely consider responses before deciding.

If you’re unsure who needs to be consulted (employees only, union reps, or both), it’s worth getting advice early. Getting the stakeholder list wrong is a common (and avoidable) risk.

How To Run A Fair Consultation Process (Step-By-Step)

When you’re busy running a small business, consultation can feel like “extra work”. But a clean process is usually faster (and cheaper) than cleaning up a messy one later.

Here’s a practical step-by-step approach you can adapt for most scenarios.

Step 1: Identify What You’re Proposing (And What’s Still Up For Discussion)

Be clear internally on:

• what the proposed change is,
• why you’re considering it, and
• what parts are genuinely open to feedback (for example, implementation timing, alternative options, transition arrangements).

A good consultation process isn’t about pretending everything is negotiable. It’s about being honest about what’s driving the change and what input could realistically influence.

Step 2: Prepare A Written Proposal And Supporting Information

In many situations (especially restructures), employees need enough information to engage meaningfully. This may include:

• the proposed new structure or roster,
• role descriptions (current vs proposed),
• reasons for change (e.g. operational needs, customer demand, cost increases), and
• any relevant data you’re relying on (without oversharing sensitive or unrelated information).

The goal is to ensure employees can understand the proposal and respond in an informed way.

Step 3: Invite Feedback And Give A Reasonable Timeframe

There’s no universal “minimum number of days”, but the timeframe needs to be reasonable given:

• the size and complexity of the change,
• how much information is being provided,
• whether employees need to seek advice or representation, and
• whether there are deadlines driving the change (and whether those deadlines are genuinely fixed).

If you rush this step, it often undermines the whole process. A slightly longer feedback window now can save you weeks later.

Step 4: Meet, Listen, And Keep Notes

Consultation doesn’t have to be one formal meeting. It can include:

• group meetings (where appropriate),
• one-on-one meetings (especially where individuals are affected differently), and
• written feedback via email.

Keep records of what was shared, what was asked, and what feedback was received. If you end up needing to demonstrate the fairness of your process, contemporaneous notes are incredibly helpful.

Step 5: Consider Feedback With An Open Mind (And Be Able To Show It)

This is the step where many employers unintentionally fall short. You don’t need to adopt all suggestions, but you should be able to show you:

• read and understood the feedback,
• turned your mind to alternatives, and
• adjusted the proposal where appropriate (or explain why not).

Where you decline feedback, explaining your reasons in plain language often prevents resentment and reduces the chance of escalation.

Step 6: Confirm The Outcome In Writing And Update Documents

Once you’ve made a final decision, confirm:

• the decision and the reasons,
• what feedback was considered,
• any changes made as a result of consultation, and
• when changes take effect.

If the decision changes employment terms (like hours, duties, pay structure, or location), make sure your written agreements are updated appropriately. This is where having a fit-for-purpose Employment Contract and supporting policies really matters.

Why Proper Consultation Matters (Even When You’re Confident You’re Right)

When you’re running a business, you’re often making decisions under pressure. Consultation can feel like it slows everything down.

But done properly, consultation is one of the best ways to protect your business while keeping your team functioning well.

It Reduces Legal Risk

A fair process helps reduce the risk of claims such as:

• unjustified disadvantage (where a change harms an employee and wasn’t handled properly),
• unjustified dismissal (including dismissal by way of flawed redundancy), and
• breach of good faith obligations.

Even where you have strong business reasons, the process is often what determines whether the change is legally defensible.

It Improves Implementation (Because You Catch Problems Early)

Your employees are often closest to the operational reality. Consultation can surface practical issues such as:

• handover gaps,
• customer impacts you didn’t anticipate,
• compliance issues (for example, fatigue risks with roster changes), and
• workflow bottlenecks.

In other words, consultation is not just a legal step - it’s a quality-control step.

It Helps You Maintain Trust During Change

Even when changes are unpopular, employees are more likely to accept them when they feel heard and respected. That can mean:

• less turnover,
• fewer disputes and absences, and
• a better culture overall.

For small businesses especially, culture and morale can have a direct impact on service delivery and revenue. Consultation is part of managing that well.

It Supports Better Performance Management

Sometimes “consultation” overlaps with performance management - for example, when changing KPIs, introducing new systems, or changing expectations in a way that affects the role. If performance issues are in the background, it’s important not to use a “consultation” process as a shortcut to avoid a proper performance process.

If you’re dealing with capability concerns at the same time as operational change, it’s worth getting advice so the process is clean and the messaging is consistent. Our guide on performance management explains how to approach this carefully.
