Unions in New Zealand:
A Guide for Employers

Unions play an important role in New Zealand workplaces. A union is a group of workers who come together to protect their rights, improve working conditions, and negotiate with employers. Unions are recognised in law and are a key part of employment relations across the country.

For businesses, unions matter because they influence pay, hours, and workplace culture. In Auckland and across New Zealand, employers often work with unions through collective agreements and bargaining processes. Knowing how unions work helps employers avoid conflict, build trust, and meet legal obligations.

In this guide you’ll learn:

• What unions are and how they work in New Zealand
• How union membership affects workers and businesses
• The role of collective agreements and bargaining
• Employer obligations when working with unions

‍

What Are Unions?

‍

Unions are organisations that represent workers. They speak on behalf of members when it comes to wages, hours, and workplace rights. In New Zealand, unions are protected by the Employment Relations Act 2000, which sets the rules for how they operate.

Workers can choose to join a union, and membership is voluntary. Some employees prefer to join because it gives them support in disputes and collective strength when negotiating with employers. Others decide not to join and negotiate their own employment agreements.

‍

Why Do Unions Matter in New Zealand?

‍

Unions have shaped workplace rights for decades. They have helped improve leave entitlements, health and safety standards, and fair pay.

For employers, unions matter because:

• They can negotiate collective agreements that apply to groups of employees.
• They can represent workers in disputes or grievances.
• They can influence workplace culture and expectations.

Auckland businesses often find that working with unions helps create stability and reduces turnover. When handled well, union relationships can make employment relations smoother, not harder.

The New Zealand Council of Trade Unions

‍

The New Zealand Council of Trade Unions (NZCTU) is the national body that brings many unions together. It acts as a voice for workers across the country and often provides guidance on policy, safety, and rights at work.

‍

Employers may come across the NZCTU when sector-wide issues are raised, such as pay equity or health and safety campaigns. Understanding its role helps businesses prepare for wider conversations that affect their workforce.

Examples of Unions in New Zealand

‍

There are many unions in New Zealand, each focusing on different industries. Some of the best-known include:

• First Union New Zealand – representing retail, finance, transport, and service workers.
• NZ Nurses Organisation – representing healthcare and support workers.
• E tū – representing workers across manufacturing, aviation, communications, and more.
• Public Service Association (PSA) – the biggest union in New Zealand, representing public sector staff.

‍

Collective Agreements in New Zealand

‍

A collective agreement is a contract between an employer and a union that covers a group of workers. These agreements usually set pay, hours, leave entitlements, and other workplace rules.

For example, a support worker in Auckland might have their salary set by a collective agreement negotiated by their union. Employers must apply the terms of the agreement to all covered employees, whether or not they are union members.

‍

Employers cannot refuse to bargain with a union, and negotiations must be conducted in good faith. This includes listening, providing information, and being open to discussion.

‍

Union Membership and Fees

‍

Union membership in NZ is optional. Workers choose whether to join and can leave at any time. Membership comes with fees, often called union fees, which are usually deducted from wages. These fees go toward funding union activities, including bargaining and legal support.

‍

Some employees ask: Is it worth joining a union in NZ? The answer depends on the individual. For many, the benefits of collective bargaining and support outweigh the costs. For others, personal negotiation may feel more suitable.

‍

For employers, it is important to respect these choices and avoid any pressure on employees either way.

‍

Employer Obligations With Unions

‍

Employers in New Zealand must follow the law when working with unions. Key obligations include:

• Allowing unions reasonable access to the workplace.
• Negotiating in good faith during collective bargaining.
• Not discriminating against employees for being union members.
• Consulting unions on certain workplace changes that affect members.

Employers who ignore these obligations risk personal grievances or legal disputes. Following the rules helps protect businesses and maintain positive working relationships.

‍

Key Takeaways for Employers

• Unions are protected by law and employers must allow access, negotiate in good faith, and avoid discrimination.
• Collective agreements set terms for groups of workers and apply to both union and non-union members.
• Union membership is voluntary; respect employee choice without pressure.
• Early, honest conversations with unions build trust and reduce disputes.
