New Zealand Consults on IFRS S2 Climate Reporting Roadmap

New Zealand's accounting standard-setter has opened public consultation on a proposed direction for the country's climate reporting, centred on a new standard that would adopt the global benchmark for climate disclosure. The External Reporting Board, known as the XRB, is asking preparers, investors and other stakeholders whether the country should build its next phase of climate reporting on IFRS S2, the standard developed by the International Sustainability Standards Board. Submissions close on 30 September 2026, and the board has stressed that no decisions have yet been taken.

 

What the Roadmap Proposes

 

The draft roadmap sets out a plan to issue a new climate standard, NZ IFRS S2 Climate-related Disclosures, and to build it on three principles. The first is international alignment, achieved by adopting IFRS S2 so that New Zealand's requirements track the standard now being taken up across a growing number of jurisdictions. The second is harmonisation with Australia, which would mean deciding how to handle any differences between IFRS S2 and the obligations Australian entities face under AASB S2 and the Corporations Act 2001. The third is local relevance, weighing whether any modifications are needed to fit New Zealand's legislative settings, established reporting practice and market conditions.

The consultation frames these as design choices rather than settled positions. The board wants evidence-based views on whether the overall direction has support, whether adopting IFRS S2 would improve the information available to investors and other primary users, and what the practical consequences would be for the entities required to report.

From a Homegrown Regime to the Global Standard

 

New Zealand was among the earliest movers on mandatory climate reporting, introducing the Aotearoa New Zealand Climate Standards, known as NZ CS, that already require designated climate-reporting entities to disclose. The proposal now on the table would move the country from that bespoke framework toward IFRS S2, which has become the reference point for climate disclosure as more jurisdictions align their rules with the work of the International Sustainability Standards Board. For the board, the appeal of that convergence is comparability, since disclosures prepared on a common basis are easier for investors to read across borders and entities that report in several markets face less duplication.

The trade-off is the cost and disruption of moving to a new standard. The board acknowledges there would be transition costs and implementation challenges, and it is explicitly asking how these should be managed rather than treating them as resolved. That framing signals an attempt to balance the benefits of joining a global system against the burden the change would place on companies that have only recently built processes around the current regime.

 

The Trans-Tasman Question

 

Harmonisation with Australia is one of the more consequential threads in the consultation, given how closely the two economies are integrated and how many entities report on both sides of the Tasman. Australia has already set its own climate disclosure obligations through AASB S2 and amendments to its corporations law, and any divergence between the New Zealand and Australian versions of the standard would create friction for groups operating across the two markets. The board is asking specifically how it should approach that harmonisation, leaving open whether it aligns tightly with Australia or preserves room for local differences where its legal framework requires them.

 

A Long Runway to Mandatory Adoption

 

Among the most notable features of the proposal is its timeline. Early adoption of NZ IFRS S2 would become available from 1 October 2026, but mandatory application would not arrive until 1 January 2033, and entities would retain the option to keep applying the existing NZ CS throughout the transition. That runway of more than six years is deliberately long, and the board says it reflects feedback calling for certainty and a phased approach rather than an abrupt switch.

The extended period is a balance between change and stability. A slower transition gives preparers time to adapt systems, data collection and assurance processes, and it reduces the risk of entities absorbing the cost of two overhauls in quick succession. It also delays the point at which New Zealand's disclosures become fully comparable with those produced elsewhere, which is part of what the consultation asks stakeholders to weigh.

What Adoption Would Mean for Reporting Entities

 

For companies within scope, the practical effect of adopting IFRS S2 would be a reporting framework aligned with the one investors increasingly expect internationally. The board points to three benefits it wants stakeholders to test: disclosures that are more comparable across markets, less duplication for entities reporting in more than one country, and clearer information for the investors and lenders who use climate data to price risk and allocate capital. Against those gains sit the practical demands of implementation, from building the data systems needed to meet the standard to securing assurance over the disclosures. The consultation asks entities directly what those implications would be, an acknowledgement that the people who will carry the compliance burden are best placed to judge whether the direction is workable.

 

What's Next

 

The consultation runs until 30 September 2026, with views gathered through written submissions and a series of in-person and virtual forums. That feedback will determine whether the draft roadmap is carried forward and will shape the design of NZ IFRS S2, including the decisions on Australian harmonisation and any New Zealand-specific modifications. If there is sufficient support, the board has said it will move to an exposure draft and a further round of consultation before any climate standard is issued. Until then the current standards remain in force, and the direction of the next phase of climate reporting rests on what preparers, investors and other users tell the board over the coming months.
