Overview
The Australia and New Zealand (ANZ) bundle combines ASRS & AASB S1/S2 for the Australian market, NZ climate standards for New Zealand, and adds ESRS Omnibus plus ISSB for companies that also need EU and global comparability. This is the right regional bundle for firms that want a local reporting base in ANZ while keeping one data model that can also support international and EU disclosure.
ASRS and AASB S2 provide the Australian sustainability and climate disclosure structure, NZ CS provides the New Zealand climate reporting structure, ESRS Omnibus covers the EU spillover layer, and ISSB acts as the global baseline.
What The Bundle Is
Australian Sustainability Reporting Standards are being implemented through AASB S1 and AASB S2, with S2 mandatory for certain entities and S1 available as the general sustainability disclosure standard. In New Zealand, the Aotearoa New Zealand Climate Standards provide the climate reporting framework, including NZ CS 1, NZ CS 2, and NZ CS 3.
When a company has EU operations, ESRS Omnibus becomes relevant because it shapes how the EU disclosure layer is simplified and applied, while ISSB keeps the whole structure globally interoperable.
Why It Exists
This bundle exists so Australia and New Zealand companies can comply with local climate and sustainability requirements without creating a disconnected second system for EU and global investors. It is especially useful for multinational groups, exporters, and listed companies that need a consistent disclosure architecture across jurisdictions.
In practical terms, it reduces duplication and makes it easier to map one climate disclosure process across several regimes.
Who Must Comply
In Australia, certain entities must apply AASB S2 for annual periods beginning on or after 1 January 2025, while AASB S1 is available voluntarily. In New Zealand, the climate standards apply to in-scope entities under the country’s climate reporting regime.
This bundle is especially useful for listed groups, financial institutions, insurers, large corporates, and cross-border firms with EU operations or investor audiences that expect ISSB-style reporting.
Where It Is Used
The bundle is used in Australia and New Zealand, but it is designed for companies that may also need EU and global disclosure compatibility. It is most relevant for sustainability teams, finance teams, investor relations, legal, and reporting functions.
Because both Australia and New Zealand frameworks are closely tied to ISSB-style logic, the bundle is already well positioned for international reporting alignment.
When It Applies
AASB S2 has already been phased into mandatory application for certain Australian entities, and AASB S1 remains available as the broader sustainability standard. New Zealand climate reporting requirements apply through the NZ climate standards for in-scope entities, and companies should treat those as active local obligations rather than future proposals.
ESRS Omnibus should be added when EU operations create reporting exposure, while ISSB should be used as the global backbone that helps unify the local standards.
Unique Requirements
Australia’s structure combines general sustainability reporting through AASB S1 with mandatory climate reporting through AASB S2. New Zealand’s structure is climate-first through the NZ climate standards, which are built to support capital allocation toward low-emissions and climate resilient activities.
That means the two countries are similar in climate orientation, but not identical in how sustainability reporting is structured.
ASRS And AASB S1/S2
ASRS in Australia is effectively implemented through AASB S1 and AASB S2, with S2 carrying the mandatory climate disclosure requirement. AASB S1 provides the general sustainability disclosure baseline, which is useful for entities that want broader sustainability reporting beyond climate alone.
This is the domestic Australian core of the bundle and should be treated as the local foundation.
NZ CS And TCFD
New Zealand climate standards are the local climate reporting framework, and they are built around climate-related risk and opportunity disclosure. TCFD-style structure remains highly relevant because the reporting model is aligned to the familiar governance, strategy, risk management, and metrics logic that climate reporters already understand.
For a New Zealand company, this is the local climate layer that connects well to international climate reporting practice.
ESRS Omnibus And ISSB
ESRS Omnibus should be added where the company has EU operations and needs to align with the European reporting layer. ISSB should be added as the global reporting baseline because it is designed to work as the international common language for sustainability and climate disclosure.
Together, they let Australia and New Zealand firms keep one reporting stack that can scale from local compliance to global comparability.
What To Pair With Local Rules
The best companion to Australia and New Zealand reporting is ISSB, because the local standards are already closely aligned to investor focused global disclosure. If the business has EU operations, ESRS Omnibus should be added; if sector metrics matter, SASB can also be layered in for industry-specific disclosure.
Where nature exposure is material, TNFD can be used as an additional layer for biodiversity and ecosystem risk.
Data Retention And Archives
Your sustainability reporting records should be retained for multiple years to support continuity, audit readiness, and comparison across reporting periods. The GAIQ™ platform preserves published reports and supporting records as accessible archives, and prior Australia and New Zealand reporting cycles can be carried forward or imported into later periods.
That makes it easier to keep local ANZ disclosures aligned with global and EU reporting needs over time.
How The GAIQ™ AI-Driven Platform Makes ANZ Reporting Simpler
GAIQ™ preloads the relevant ESG Standards Frameworks based on your DMA results, so your team starts with the correct ASRS, AASB S1/S2, NZ CS, ESRS, or ISSB scope already configured. It helps map local Australian and New Zealand data into EU and global reporting formats and reduces duplicated work across jurisdictions.
GAIQ™ also makes the active framework visible in the app header and D Data pages, so users always know which standards are selected, assigned, or both.
Next Steps For Your Team
Use the Australia and New Zealand bundle when you need a local ANZ reporting base that can also support EU and global comparability. Pair ASRS with AASB S1/S2 in Australia, use NZ CS in New Zealand, add ESRS Omnibus for EU operations, and use ISSB as the global baseline. Consider adding SASB industrial standards where sector specific reporting is required.
Adopt AI technology to automate data collection, mapping, and reporting workflows, which can significantly reduce the time and effort required for ESG reporting.

Executive Summary
The Australia and New Zealand bundle combines local ANZ sustainability and climate standards with ESRS Omnibus and ISSB for EU and global reach. It is the best fit for companies that want one reporting structure spanning local compliance, EU spillover, and international comparability.
This gives ANZ firms a practical bridge from domestic reporting into global sustainability disclosure.
