Employment Relations Act 2000: A Guide for NZ Employers

Gemma Stringer | Last updated May 2026

The Employment Relations Act 2000 (often called the ERA) is the main piece of employment law in New Zealand. It sets the rules for how employers and employees work together, covering everything from employment agreements to collective bargaining.

For businesses in Auckland and across New Zealand, understanding the Employment Relations Act matters. It helps employers meet legal obligations, reduce workplace disputes, and build fair, respectful workplaces. Not following the law can lead to penalties, complaints to the Employment Relations Authority, and reputational risks.

In this guide you’ll learn:

  • What the Employment Relations Act 2000 is and why it exists
  • Key sections and principles employers must follow
  • Employer obligations for agreements, bargaining, and workplace changes
  • How the Act is applied in common situations such as termination and redundancy

What Is the Employment Relations Act 2000?

The Employment Relations Act 2000 is the foundation of New Zealand employment law. It replaced earlier legislation and focuses on building employment relationships based on mutual trust, fairness, and good faith.

At its core, the ERA requires both employers and employees to act in good faith. This means being open, honest, and respectful when dealing with each other, whether that’s during contract negotiations, workplace change, or dispute resolution.

The current employment act in NZ is the Employment Relations Act 2000, which has been updated several times. For example, the Employment Relations Act 2023 amendments refined rules around collective bargaining and minimum entitlements.

Why the Employment Relations Act Matters for NZ Businesses

Many small and medium businesses in New Zealand underestimate the importance of employment legislation until an issue arises. For example, an Auckland café owner recently faced a dispute after not providing written employment agreements to staff. The case went to the Employment Relations Authority and ended in costs that could have been avoided with compliance.

By understanding the ERA, employers can:

  • Stay compliant with New Zealand employment law
  • Avoid costly disputes and penalties
  • Create positive workplace culture built on fairness
  • Manage redundancy, restructuring, and termination fairly and legally

Key Principles of the Employment Relations Act

Good Faith in Employment Relations

Section 4 of the Employment Relations Act 2000 outlines the duty of good faith. Employers must communicate honestly, share relevant information, and consult employees before making decisions that affect them.

Defining Who Is an Employee

Section 6 of the Act defines what an employee is. This is important because some workers may be incorrectly treated as contractors when, under the law, they are employees with rights and protections.

Minimum Standards and Agreements

Employers must provide written employment agreements that meet minimum entitlements under New Zealand employment law. These agreements should cover pay, hours, leave, breaks, and other key terms.

Employment Relations Act 2000 in Practice

Employment Relations Act 2000 Termination

When ending employment, employers must follow fair and reasonable processes. This includes giving employees the chance to respond to concerns and following proper notice periods. Wrongful termination can lead to cases at the Employment Relations Authority.

Employment Relations Act 2000 Redundancy

Redundancy is only lawful if it is genuine. Employers must consult staff in good faith, provide reasons, and explore alternatives. Compensation is not automatically required, but clear processes protect both the business and staff.

Part 6AA of the Employment Relations Act 2000

This section covers the transfer of employees in industries like cleaning and catering when a business changes ownership. It protects vulnerable workers by ensuring their terms and conditions are maintained.

Employment Relations Act 2000 Breaks

Employees are entitled to rest and meal breaks. The ERA sets out how often breaks should be given depending on shift length. Employers who ignore this can face penalties under employment legislation.

Key Takeaways for Employers

  • Understand and apply the principles of good faith in every employment relationship.
  • Always provide written employment agreements that meet legal requirements.
  • Follow fair processes for redundancy, restructuring, and termination.
  • Keep up to date with amendments such as the Employment Relations Act 2023 and 2024 changes.
