New Zealand Pay Equity Overview

Overview

New Zealand's commitment to pay equity is rooted in a long history of legislative efforts to eliminate sex-based discrimination in remuneration. The foundational Equal Pay Act of 1972 outlawed direct discrimination in wage rates for men and women performing the same job, extending principles first applied to the public service in 1960. However, the broader concept of 'pay equity'—ensuring equal pay for different work of equal value—gained clearer legal footing with the Equal Pay Amendment Act 2020. This amendment provided a structured process for workers, often through unions, to raise claims addressing the systemic undervaluation of female-dominated occupations. The underlying philosophy acknowledges that certain roles, historically or predominantly performed by women, have been undervalued due to sex-based bias, leading to suppressed wages across entire sectors and contributing significantly to the national gender pay gap.

The evolution of pay equity in New Zealand reflects a continuous effort to refine the legal framework to effectively tackle persistent gender pay gaps. While the Equal Pay Act 1972 initially focused on 'equal pay for equal work,' the 2020 amendments broadened its scope to explicitly address 'pay equity' or 'equal pay for work of equal value.' This shift was crucial for addressing occupational segregation, where women are often concentrated in lower-paid roles, and under-representation in higher-level positions, which are significant drivers of the gender pay gap. The most recent Equal Pay Amendment Act 2025, enacted on May 6, 2025, represents a significant recalibration of the pay equity process, introducing stricter criteria for raising claims and a more defined approach to comparator selection, aiming to streamline the process while ensuring financial sustainability for employers.

Key statistics highlight the ongoing challenge of achieving full pay equity in New Zealand. As of the June 2025 quarter, the national gender pay gap stood at 5.2%, a decrease from 8.2% in the June 2024 quarter, marking the lowest since records began in 1998. Despite this overall reduction, significant disparities persist for women from certain ethnic groups, with Asian women experiencing a pay gap of 10.2%, wāhine Māori at 12%, and Pacific women at 15.8% in the same period. These figures underscore that while progress has been made, the systemic nature of pay inequity, particularly for vulnerable workforces and those facing intersectional discrimination, remains a critical area of focus for ongoing policy and legislative development, necessitating a nuanced approach to regulatory interventions.

Regulatory Approach

New Zealand's regulatory approach to pay equity has evolved from a primarily court-driven model to one that emphasizes collective bargaining and dispute resolution, though recent amendments have introduced more stringent requirements. The Equal Pay Amendment Act 2020 integrated pay equity claims into the existing bargaining framework, encouraging employers, workers, and unions to negotiate in good faith, with mediation and resolution services available as a primary recourse before court action. This approach aimed to lower the barrier for initiating claims and foster a more collaborative resolution process, administered by the Ministry of Business, Innovation and Employment (MBIE), which provides central guidance and resources on the pay equity framework.

The Equal Pay Amendment Act 2025, which came into force on May 14, 2025, significantly altered the regulatory landscape by introducing stricter thresholds and a more structured process for pay equity claims. Under the 2025 amendments, new claims must demonstrate 'merit' and relate to work performed by a workforce that has been at least 70% female for 10 consecutive years, a notable increase from the previous 60% threshold. This change, along with a tightened hierarchy for comparator selection, aims to ensure that claims are robustly evidenced and closely related to the employer, thereby reducing the number of claims that may lack sufficient grounds or are deemed unsustainable. The government's rationale for these changes included concerns about the previous Act not effectively identifying genuine pay equity issues and the financial sustainability of settlements, particularly in government-funded sectors like health and education.

Compliance with pay equity regulations in New Zealand is primarily driven by the claims-based process, where employees or unions initiate action. While there is no mandatory pay gap reporting legislation for all private sector employers, the Ministry for Women has developed a Gender Pay Gap Toolkit, including a calculator, to encourage voluntary measurement and action by businesses. In the public service, the Kia Toipoto – Public Service Pay Gaps Action Plan 2021-2024 requires government agencies and Crown entities to publish annual pay gap data and action plans, demonstrating a dual approach of voluntary encouragement for the private sector and mandatory requirements for the public sector. The 2025 amendments also introduced provisions allowing employers to discontinue claims under broader grounds and removed the ability for the Employment Relations Authority to award back pay, instead encouraging negotiated settlements and phased-in remuneration.

Key Pay Equity Legislation

NZ-EQUAL-PAY-ACT-1972: New Zealand Equal Pay Act (Act, In Force (Amended), 1972)
The Equal Pay Act 1972 is the cornerstone of New Zealand's equal pay legislation. Its primary purpose was to eliminate and prevent discrimination based on sex in the rates of remuneration for male and female employees in paid employment. Initially, it focused on ensuring that men and women received the same pay for performing the same or substantially similar work. Over time, through judicial interpretation and subsequent amendments, its scope expanded to encompass the broader principle of 'pay equity,' meaning equal pay for work of equal value, even if the jobs are different. The Act is administered by the Ministry of Business, Innovation, and Employment (MBIE) and provides the legal basis for employees and unions to challenge sex-based undervaluation of work, setting the fundamental rights and obligations for employers across all sectors.
NZ-EQUAL-PAY-AMENDMENT-2020: NZ Equal Pay Amendment (Amendment, In Force, 2020)
The Equal Pay Amendment Act 2020, which came into force on November 6, 2020, significantly reformed the process for raising and resolving pay equity claims. This amendment explicitly entrenched the concept of "pay equity" into law, providing a clearer framework for addressing systemic undervaluation in female-dominated occupations. It shifted the claims process from a purely court-based approach to one that encouraged collective bargaining between employers, workers, and unions, with court action as a last resort. The 2020 Act also clarified that a pay equity claim could be raised if the work was predominantly performed by a workforce of approximately 60% or more female members and there was an arguable case of historical or current undervaluation, thereby making the process more accessible for claimants.
RET-NZ-NA-EQPYAM-2025: NZ Equal Pay Amendment Act 2025 (Act, In Force, 2025)
Enacted on May 6, 2025, and coming into force on May 14, 2025, the Equal Pay Amendment Act 2025 introduced substantial changes to the pay equity claims process. This Act raised the threshold for raising pay equity claims, now requiring the workforce to be at least 70% female for 10 consecutive years, and demanding evidence that the claim has 'merit' and relates to historically and currently undervalued work. It also introduced a stricter hierarchy for selecting male comparators, prioritizing those from the same employer. Furthermore, the 2025 amendments discontinued all existing unsettled claims, made review clauses in existing settlements unenforceable, and removed the Employment Relations Authority's ability to award back pay, instead mandating phased-in remuneration for new settlements, significantly altering the landscape for future claims and existing agreements.

Covered Employers

New Zealand's pay equity legislation, primarily the Equal Pay Act 1972 and its subsequent amendments, applies broadly to all employers across both the public and private sectors. The original 1972 Act extended the principles of equal pay, which were first established for government employees in 1960, to the private sector. This means that any employer in New Zealand, regardless of their size or industry, is subject to the fundamental requirements of paying men and women equally for the same work and equitably for different work of equal value. There are no specific size thresholds that exempt smaller employers from these fundamental obligations, although the practicalities of raising and resolving claims may differ between large and small organizations, with larger entities often having more structured HR processes and union representation.

The Equal Pay Amendment Act 2025 introduced significant changes that indirectly affect the scope of covered employers by altering the criteria for eligible claims. While the core obligation to provide equal pay for work of equal value remains universal, the new requirements for a pay equity claim to relate to a workforce that has been at least 70% female for 10 consecutive years will influence which employers are likely to face formal pay equity claims. This threshold primarily impacts claims addressing systemic undervaluation in female-dominated occupations, rather than direct equal pay claims for the same work. Consequently, employers in sectors traditionally characterized by a high proportion of female workers, such as care, administration, education, and social services, are particularly relevant under these provisions and may face increased scrutiny or claims activity.

Furthermore, the 2025 amendments also impact multi-employer claims and existing settlements. Employers can now opt out of multi-employer claims without justification, and all existing or previously agreed review clauses in settlements are discontinued. This means that employers who were part of ongoing multi-employer claims or had review clauses in past settlements will need to re-evaluate their positions under the new framework, potentially leading to a fragmentation of claims. While the legislation does not explicitly define exemptions based on sector, the practical implications of the new claim thresholds and comparator rules may lead to a more focused application of the pay equity claims process on specific industries or types of work. The government's stated aim for these changes included ensuring financial sustainability for employers, particularly in government-funded sectors, by managing the scope and cost of settlements.

Employee Rights

Employees in New Zealand possess fundamental rights to equal pay for the same work and pay equity for work of equal value, enshrined primarily in the Equal Pay Act 1972. This legislation ensures that there is no differentiation based on sex in remuneration rates, encompassing wages, salaries, and other benefits. Employees who believe their work is subject to sex-based undervaluation can raise a pay equity claim, either individually or, more commonly and effectively, through their union. The process for exercising these rights involves engaging with their employer in a good faith bargaining framework, with access to mediation and dispute resolution services provided by the Ministry of Business, Innovation and Employment (MBIE) if an agreement cannot be reached. Unions play a crucial role in representing members in these claims, and employers are generally required to notify employees covered by a union-raised claim, ensuring transparency within the process.

The Equal Pay Amendment Act 2020 streamlined the process for employees to initiate pay equity claims, making it simpler to bring forward cases of alleged undervaluation. However, the subsequent Equal Pay Amendment Act 2025 introduced more stringent requirements for raising a claim. Under the 2025 amendments, an employee or union must now demonstrate that the claim has 'merit,' meaning there are reasonable grounds to believe the work has been historically and is currently undervalued due to systemic sex-based discrimination. Additionally, the claim must relate to a workforce that has been at least 70% female for the preceding 10 consecutive years. These changes mean that employees must meet a higher evidentiary bar at the outset of the claims process, potentially making it more challenging to initiate and progress claims without robust preliminary research and data.

Employees also have rights related to information and comparator data, although these have been refined by recent amendments. The Ministry of Business, Innovation and Employment (MBIE) maintains a pay equity data repository through its Workplace Online Portal, which allows parties to an ongoing pay equity claim to submit and request anonymized comparator information from past settlements. Access to this data is conditional on being part of an ongoing claim and disclosing any conflicts of interest, with strict confidentiality requirements to protect privacy. While there are currently no legal requirements for employers to proactively disclose salary details for specific positions to applicants or employees, the ability to access anonymized comparator data from past settlements can be a valuable tool for employees and unions in substantiating their claims. However, the 2025 amendments also removed the enforceability of review clauses in existing settlements, meaning that if a pay gap reopens, a new claim cannot be raised for 10 years after the previous settlement, unless the Employment Relations Authority or Employment Court allows it under exceptional circumstances.

Governance & Enforcement Bodies

Several key government bodies are responsible for the governance and enforcement of pay equity regulations in New Zealand. The Ministry of Business, Innovation and Employment (MBIE) is the primary administering agency for the Equal Pay Act 1972 and its amendments. MBIE provides comprehensive guidance on the pay equity framework, manages the pay equity data repository, and facilitates the submission and request of comparator data through its Workplace Online Portal. Their role is crucial in ensuring that the legislative framework is understood and applied by employers and employees alike, and they are often involved in the initial stages of providing information, resources, and mediation services related to pay equity claims, acting as a central hub for information and support.

The Employment Relations Authority (ERA) and the Employment Court serve as the judicial bodies for resolving pay equity disputes that cannot be settled through negotiation or mediation. The ERA is an independent body that investigates and makes determinations on employment relationship problems, including pay equity claims. If parties reach an impasse in their bargaining, they can refer the matter to the ERA for a determination, which is binding unless appealed. Decisions made by the ERA can be appealed to the Employment Court, which is a specialist court dealing with employment law matters and provides a higher level of judicial review. These bodies ensure that legal principles are applied, and fair outcomes are reached when parties cannot agree voluntarily. The 2025 amendments, however, removed the ERA's ability to award back pay, instead requiring phased-in remuneration for new determinations, shifting the financial burden and timing of adjustments.

The Human Rights Commission (HRC) also plays a significant role in advocating for and monitoring human rights, including the right to equal pay for work of equal value. While not directly involved in the claims resolution process in the same way as MBIE or the ERA, the HRC has a statutory role to promote equal employment opportunities and monitor New Zealand's compliance with international human rights conventions. The HRC has actively intervened in legal cases related to pay equity, submitted to select committees on legislative changes, and has conducted inquiries, such as the Inquiry into the Pacific Pay Gap, to highlight systemic issues and recommend legislative changes, including advocating for pay transparency. Their work provides an important oversight and advocacy function, ensuring that pay equity remains a prominent human rights issue in New Zealand and holding the government accountable to its international obligations.

Monitoring & Compliance

Monitoring and compliance with pay equity regulations in New Zealand primarily operate through a claims-based system, where employees or unions initiate action to address alleged sex-based undervaluation. The process begins with raising a pay equity claim with the employer, which then triggers a bargaining framework under the Equal Pay Act. Employers are required to engage in good faith negotiations, and if an agreement is reached, a pay equity settlement is signed. Once a settlement is made or a determination by the Employment Relations Authority (ERA) or Employment Court is issued, employers are required to send a copy of the settlement or determination to the Chief Executive of the Ministry of Business, Innovation and Employment (MBIE). This submission contributes to MBIE's pay equity data repository, which stores anonymized information from settled claims and comparator data, providing valuable insights for future claims and policy development.

The 2025 amendments to the Equal Pay Act introduced more rigorous criteria for the initial assessment of claims, significantly impacting monitoring and compliance. To be eligible, a claim must now demonstrate 'merit' and relate to a workforce that has been at least 70% female for 10 consecutive years. The employer must decide within 60 working days whether the claim is eligible and has merit. If the employer disagrees, the claim can be halted, requiring the union to go to court to overturn the decision, potentially extending the process significantly and increasing legal costs. This places a greater burden on claimants to provide substantial evidence of undervaluation and discrimination upfront, shifting the initial assessment responsibility more heavily onto employers. The assessment process itself involves comparing the work of claimants to suitable male comparators not subject to sex-based undervaluation, with a structured hierarchy guiding comparator selection to ensure consistency and fairness.

While there are no mandatory pay equity audits for private sector employers, the government encourages voluntary action and provides tools for self-monitoring. The Ministry for Women provides a Gender Pay Gap Toolkit, including a calculator, to help businesses measure their gender pay gaps and identify actions to reduce them. In the public service, the Kia Toipoto – Public Service Pay Gaps Action Plan 2021-2024 mandates annual pay gap reporting and action plans for government agencies and Crown entities, demonstrating a commitment to transparency and accountability within the state sector. The ERA and Employment Court provide avenues for dispute resolution when parties cannot agree, ensuring that legal recourse is available for unresolved claims. However, the 2025 amendments removed review clauses in existing settlements, meaning that if pay gaps re-emerge, a new claim cannot be raised for 10 years unless specifically allowed by the Authority or Court, which could impact long-term compliance and the sustained elimination of pay inequities.

Penalties & Enforcement

Enforcement of pay equity in New Zealand primarily occurs through the dispute resolution mechanisms established under the Equal Pay Act 1972 and the Employment Relations Act 2000. When parties to a pay equity claim cannot reach a negotiated settlement through good faith bargaining, they can refer the matter to the Employment Relations Authority (ERA) or, subsequently, the Employment Court. These bodies have the power to investigate the claim, hear evidence, and make determinations regarding pay equity claims, ensuring that legal principles are applied to correct identified sex-based undervaluation. Prior to the 2025 amendments, the courts had discretion in awarding back pay, generally restricted to the date a pay equity claim was first raised, to encourage swift resolution and compensate for past discrimination. This framework aimed to provide a clear pathway for redress when sex-based undervaluation was identified and not voluntarily corrected by employers.

The Equal Pay Amendment Act 2025 introduced significant changes to the types of remedies and enforcement mechanisms available. Notably, the ability for the Employment Relations Authority to award back pay when fixing remuneration has been removed. Instead, when the Authority determines a pay equity claim, any new remuneration must be phased in over three equal instalments, a year apart from each other, starting from the date of the determination. This change aims to support financial sustainability for employers, particularly in government-funded sectors, and to encourage negotiated settlements rather than relying on judicial determinations for retrospective payments. The removal of back pay provisions has been a point of contention, with critics arguing it may disincentivize employers from resolving claims quickly and prolong the period during which workers are underpaid, thereby weakening the enforcement mechanism for historical undervaluation.

Beyond the specific remedies for pay equity claims, general employment law penalties for breaches of the Employment Relations Act 2000, such as failing to bargain in good faith, could theoretically apply in the context of pay equity negotiations, carrying potential fines or other sanctions. However, the primary enforcement focus within the pay equity framework itself is on achieving a settlement or determination that corrects the undervaluation, rather than punitive fines for the undervaluation itself. The 2025 amendments also expanded the grounds on which employers can discontinue a claim, for instance, if they consider the comparator work not substantially similar or if the claim lacks 'merit.' If an employer does not agree that a claim has merit, the union would need to go to court to challenge this decision, potentially leading to prolonged legal battles and increasing the burden on claimants. Appeals against ERA determinations can be made to the Employment Court, and further appeals on points of law can be taken to the Court of Appeal and the Supreme Court, ensuring a multi-tiered judicial review process for complex cases.

International Alignment

New Zealand demonstrates a strong commitment to international labour standards and human rights conventions related to equal pay and non-discrimination. The country ratified the International Labour Organization (ILO) Convention No. 100 on Equal Remuneration in 1983, which calls for the application of the principle of equal remuneration for men and women workers for work of equal value through objective appraisal of jobs. Concurrently, New Zealand also ratified ILO Convention No. 111 on Discrimination (Employment and Occupation), which promotes equal employment opportunity and prohibits discrimination based on sex, among other grounds. These ratifications underscore New Zealand's long-standing international obligations to address gender-based pay disparities and have significantly influenced the development of its domestic legal framework, including the Equal Pay Act 1972 and the Human Rights Act 1993.

In addition to ILO conventions, New Zealand is a signatory to other key international human rights instruments that reinforce the right to equal pay. This includes the 1948 Universal Declaration of Human Rights, which declares that everyone has the right to equal pay for equal work, and the Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW), ratified in 1985. These international commitments have influenced the development of New Zealand's domestic legislation, including the Human Rights Act 1993 and the New Zealand Bill of Rights Act 1990, which prohibit sex discrimination in employment. The Human Rights Commission actively monitors New Zealand's compliance with these international obligations and has voiced concerns when domestic legislative changes are perceived to undermine these commitments, acting as a critical independent voice in the human rights landscape.

While New Zealand's legislative framework generally aligns with international principles, recent amendments have drawn scrutiny regarding their impact on the practical realization of pay equity. The Equal Pay Amendment Act 2025, for instance, has been criticized by some, including the Human Rights Commission, for potentially making it harder to correct pay inequities and for being inconsistent with human rights best practice. The changes, such as raising claim thresholds, removing back pay provisions, and discontinuing existing claims, are seen by some as a step backward in advancing pay equity, despite the government's stated aim of ensuring a workable and sustainable process. Compared to some European countries that have mandatory pay gap reporting for all employers, New Zealand's approach remains primarily claims-based, with voluntary reporting initiatives for the private sector, indicating a different regulatory philosophy in practice that relies more on individual or collective action rather than proactive employer obligations.

Future Developments

The landscape of pay equity in New Zealand is currently shaped by the recent and significant changes introduced by the Equal Pay Amendment Act 2025, which came into force on May 14, 2025. This Act has already had a profound impact, leading to the discontinuation of 33 active pay equity claims and requiring them to be refiled under the new, stricter criteria. Therefore, the immediate future will involve parties navigating these new requirements, including the higher threshold for female-dominated work (70% for 10 consecutive years) and the need to demonstrate 'merit' with robust evidence at the outset of a claim. This will likely lead to a period of adjustment as unions and employers adapt their strategies to the revised legal framework, potentially resulting in fewer claims being initiated or a longer, more complex initial assessment phase.

The political outlook surrounding pay equity remains dynamic and contentious. The 2025 amendments, passed under urgency, have faced strong criticism from unions and the Human Rights Commission, who argue that the changes undermine human rights obligations and make it significantly harder for women in female-dominated professions to achieve pay equity. The Human Rights Commission has commended the People's Select Committee on Pay Equity for providing a platform for those impacted by the changes to voice their concerns, and has indicated potential intervention in legal challenges to the amendments. This suggests that further legal challenges or advocacy efforts to reverse or modify aspects of the 2025 Act could be a feature of future developments, potentially leading to ongoing debates about the balance between a workable claims process, financial sustainability for employers, and the full realization of pay equity principles.

In terms of broader reforms, the Ministry for Women is actively working on a second iteration of its Gender Pay Gap Toolkit, specifically designed to address ethnic pay gaps, which remain significantly wider than the national average. This initiative, expected to launch later in 2025, indicates a continued government focus on addressing intersectional pay disparities, acknowledging that a one-size-fits-all approach may not suffice. While mandatory pay gap reporting for the private sector is not currently legislated, it has been proposed in the past, and organizations like Mind the Gap continue to advocate for its implementation, citing international best practices. The ongoing efforts to collect and analyze pay data, coupled with the political and social pressures from advocacy groups, suggest that while the 2025 amendments have set a new course, the conversation around further legislative or policy interventions to close all pay gaps in New Zealand is likely to continue, with potential for future shifts in regulatory emphasis.
