Wellington, NZ - February 3rd, 2026 - State Services Commissioner Andrea Reed today announced a comprehensive review of data and privacy risk management practices across all New Zealand government departments when utilizing third-party providers. The initiative, spurred by a growing number of data breaches and increasing concerns surrounding external contractor oversight, aims to bolster the nation's data security posture and protect sensitive citizen information.

The review, slated for completion by mid-February, will be undertaken by an independent expert and will delve into the current data handling practices, identify vulnerabilities, and assess the efficacy of existing oversight mechanisms for third-party contractors. This includes scrutinizing contracts, due diligence processes, and ongoing monitoring of data access and security protocols.

Commissioner Reed emphasized the increasing reliance on external providers for service delivery, stating, "Many government departments are inextricably linked to third-party providers. This often necessitates the sharing of significant amounts of data, and it's crucial we thoroughly understand how this data is being managed and, critically, protected."

The move follows a pattern of escalating cyber incidents targeting government agencies and their associated vendors. The most recent and significant breaches - the 2024 Inland Revenue Department (IRD) cyberattack and the 2025 Ministry of Health ransomware attack - both implicated third-party contractors as key vulnerabilities. The IRD incident compromised the personal information of thousands of New Zealanders, revealing systemic weaknesses in data security procedures within a contracted entity. The Ministry of Health attack, while impacting the Ministry directly, also highlighted the risk of cascading failures when third-party vendors are compromised, disrupting vital healthcare services.

Experts point to several factors contributing to the heightened risk. The increasing sophistication of cyberattacks, coupled with the growing complexity of supply chains, creates a larger attack surface for malicious actors. Many government departments, while possessing robust internal security measures, often lack the resources or expertise to effectively audit and monitor the security practices of numerous third-party providers, particularly smaller firms.

"The challenge isn't just about technical security," explains Dr. Eleanor Vance, a cybersecurity specialist at Victoria University of Wellington. "It's about governance, risk assessment, and contract management. Departments need to be asking tough questions during the procurement process - what security standards are in place, what data encryption methods are used, how is access control managed, and what incident response plans are in place? And then, crucially, they need to verify those claims through ongoing audits."

The review will likely focus on several key areas, including: data minimization - ensuring only necessary data is shared with third parties; data encryption - both in transit and at rest; access control - limiting data access to authorized personnel only; incident response planning - establishing clear procedures for handling data breaches; and contractual obligations - ensuring third-party contracts include stringent data security requirements and liability clauses.

The findings of the review are expected to inform the development of new guidelines and best practices for government departments, potentially leading to stricter vetting procedures for third-party providers and a more robust framework for data governance. Some commentators suggest the government may consider mandating specific security certifications for vendors handling sensitive data, similar to international standards like ISO 27001.

The Commissioner's decision has been welcomed by privacy advocates. "This review is a necessary step in protecting the privacy of New Zealand citizens," said Kate Morrison, spokesperson for the Digital Rights Alliance. "Government agencies have a responsibility to ensure that the data they collect and share is handled securely, and that extends to their third-party providers. We urge the Commissioner to take a proactive approach and implement meaningful reforms."

The results of the review, due in just over a week, will be keenly watched by both government officials and the public, as New Zealand grapples with the increasing challenges of data security in an increasingly interconnected world. The stakes are high, not only for the protection of personal information but also for maintaining public trust in government services.
