New Zealand’s Regulatory Standards Board (RSB) becomes operational on 1 July 2026, marking the full commencement of Part 2 of the Regulatory Standards Act 2025. From that date, every government-initiated bill and new regulation must carry a formal assessment of its consistency with the Act’s principles – and the board will be watching.
The Act received Royal Assent on 18 November 2025 and partly came into force on 1 January 2026, but its most substantive provisions take effect on 1 July: the Consistency Accountability Statement (CAS) regime, the board’s inquiry powers, and enhanced stewardship obligations for chief executives of public service departments.
The RSB was appointed in April 2026 on the recommendation of Regulation Minister David Seymour. Its chair is Paul Ridley-Smith, a Wellington-based lawyer and former general counsel at Contact Energy. The five other members are Ian Chamberlain, Julie Hardaker, Professor Ananish Chaudhuri, Carl Hansen, and Dr Nicola Swain.
What the board does from 1 July
From commencement, every government-initiated bill or regulation introduced to Parliament must be accompanied by a CAS – a formal assessment of consistency with the Act’s principles of responsible regulation. Those principles cover the rule of law, protection of liberties and property rights, access to courts, tax and levy powers, and the requirements of good law-making. Where a bill or regulation departs from the principles, the responsible minister must provide a public statement explaining why the government is proceeding.
The board also begins its own independent work programme. The RSB has authority to inquire into existing legislation – either on its own initiative or in response to public complaints – and report on whether it’s consistent with the Act’s principles. A public complaints process operates from commencement through the Ministry for Regulation.
The board can scrutinise and report. It cannot compel. There’s no mechanism by which the RSB can require Parliament to amend or repeal legislation, and the Act expressly states that inconsistency with the principles does not affect the legal validity of any law. The architecture is one of transparency and political accountability, not judicial enforcement. The Ministry for Regulation provides secretariat support, though the board performs its statutory functions independently of ministers and government agencies.
The contested path to commencement
The Act passed with the support of the National, ACT, and New Zealand First (NZ First) parties along party lines, in votes of 68 to 55. It did so despite a Waitangi Tribunal finding that the Crown had breached Treaty of Waitangi principles by advancing the bill without meaningful consultation with Māori, and over the objections of 98.7% of more than 159,000 public submitters – a volume of opposition without recent parallel in New Zealand’s legislative history.
The Modern Regulator covered those dynamics in detail as the bill advanced: the near-universal expert opposition, the property rights debate, and the question of whether a transparency regime can deliver regulatory quality improvement or merely compliance overhead. The record public opposition at select committee and the broader constitutional critique are documented in those earlier pieces.
What’s new as of 1 July is that theory becomes practice. The RSB will begin receiving complaints. Agencies will begin producing CASs. The first bills introduced to Parliament after commencement will be the first test of whether the new documents say anything substantive or function as formulaic checklists.
Political uncertainty ahead
The Act’s operational start coincides with heightened uncertainty about its long-term survival. Labour, the Greens, and Te Pāti Māori have all committed to repealing it if they form the next government. NZ First, which voted for the Act, has since signalled it would support repeal if re-elected. National’s deputy leader Nicola Willis told Newstalk ZB – as reported by The Spinoff – that while National hadn’t taken a position, it was “not impossible” the party would campaign on repeal, saying it was conceivable National would go to voters arguing the Act “hasn’t operated as we’d hoped and we want to repeal it.”
That context matters for how agencies approach implementation. How quickly the board moves – and how seriously agencies treat the CAS regime – will be shaped in part by assessments of whether this framework will still exist in 18 months.
Whatever its long-term political prospects, the Regulatory Standards Board opens for business as the most formally constituted external scrutiny body New Zealand has applied to the quality of its regulatory legislation.
TMR has followed the Regulatory Standards Bill from its introduction in May 2025, through the record public opposition at select committee, to the broader constitutional critique of what the Act represents.
