Corruption in New Zealand
New Zealand is regarded as having one of the lowest levels of corruption in the world, but Transparency International and the Serious Fraud Office have expressed concerns recently about the growth of organised crime in New Zealand, poor accountability in public sector procurement, weaknesses in border controls and an increase in fraud and cybercrime.
Corruption involves activities such as bribery, embezzlement, nepotism, fraud, and conflicts of interest, among others. The Crime and Victims Survey in 2024 revealed that fraud is the fastest-growing crime in New Zealand, making up nearly 30% of all crimes. Online scams are particularly prevalent, with research suggesting that two-thirds of New Zealanders have been targeted and one-third have fallen victim to scams. Digital fraud schemes, including business email compromises and crypto investment scams, are becoming more sophisticated, often utilising social engineering tactics and artificial intelligence.
A 2025 Ministerial Advisory Group defined corruption as the abuse of power, particularly in the context of organised crime. The group highlighted that despite New Zealand's reputation for being relatively free from corruption, organised crime, particularly drug importation, represents a growing "insider threat" involving trusted individuals within institutions, especially at the borders. Airport baggage handlers, customs employees, and police officers have been implicated in facilitating illicit activities. Organised crime rings often use employees to retrieve drug shipments before they are inspected, a trend consistent with global findings on maritime drug seizures.
Business-related fraud is also increasing, with external parties such as vendors or third-party suppliers, responsible for 84% of fraud incidents. Fraud in New Zealand spans various sectors, including local councils, government agencies, and educational institutions. Cyber-enabled fraud, procurement fraud, and large-scale scams have been on the increase, particularly targeting businesses in high-value industries like law firms and real estate. The National Cyber Security Centre reported that scams had caused financial losses exceeding NZ$25 million in 2024, a 40% increase from 2023. However, estimates suggest that the total cost of fraud may be as high as NZ$2 billion annually, including unreported cases.
Tax evasion and avoidance are also significant issues. Tax avoidance, primarily through multinational corporations shifting profits offshore, results in revenue losses, such as $167 million in 2023. Conversely, tax evasion, which is illegal, is estimated to cost New Zealand around NZ$1.2 billion annually, though only a small percentage of offenders are prosecuted. The national tax debt in 2024 stood at NZ$8.5 billion, with efforts to recover over $4 billion in unpaid taxes by mid-2025.
Benefit fraud is much smaller in scale, with most cases involving overpayment recovery rather than criminal charges. In the 2021/22 period, benefit fraud led to overpayments of around NZ$2.4 million, although the total scale of welfare fraud in New Zealand is believed to be between NZ$10-20 million annually.
The prevalence of political corruption is unclear, but concerns are growing about the impact of political lobbying and conflicts of interest. The lobbying industry is unregulated in New Zealand, allowing former politicians to transition into lobbying roles, potentially influencing policy decisions. Examples include lobbying efforts by industries like finance, alcohol and tobacco, which have contributed to weak regulations and public crises, such as the finance company collapses and the leaky homes crisis.
A related concern is the lack of transparency surrounding political donations, which can grant undue influence to wealthy individuals and corporations. Scandals involving the National Party in 2018 and the New Zealand First Foundation in 2019 revealed loopholes in donation laws and raised questions about the integrity of the political process.
While corruption in New Zealand’s police force remains relatively low, individual officers have been involved in several controversies, including the manipulation of evidence and the use of prison snitches which have led to historical wrongful convictions. The Police National Integrity Unit is responsible for monitoring and investigating police misconduct.
