Who's using the ISO 55000 standards in New Zealand? An update for 2026
In 2023 we examined who was using the ISO 55000 standards across New Zealand's infrastructure sector. This article updates that analysis, drawing on current certification data, sector-specific public disclosures, and the changing policy environment.
New Zealand's infrastructure sector faces well-documented challenges, and Te Waihanga New Zealand Infrastructure Commission has been candid that the problem is not solely one of investment quantum. The sector also has a maturity problem. Too many organisations are failing to manage the assets they already own in a systematic, value-focused way. It is in this context that the ISO 55000 standards, the international benchmark for asset management systems, represent a high-leverage opportunity for improvement.
The ISO 55000 standards
The ISO 55000 series establishes international consensus on how asset management can be implemented to ensure organisations realise full value from assets. ISO 55001, the core standard, defines the requirements for an asset management system: the set of policies, objectives, and processes an organisation should put in place to manage assets through their lifecycle. The second edition of ISO 55001 was published in July 2024 and we summarised the key changes in a separate article. The 2024 edition materially strengthens requirements in areas where New Zealand infrastructure organisations are weakest, particularly around asset management decision-making, data and information, and knowledge management.
The ISO Survey 2024, conducted in collaboration with the International Accreditation Forum, recorded 687 valid certificates worldwide, modest relative to other management system standards, reflecting the standard's focus on capital-intensive sectors rather than breadth of commercial adoption. Many more organisations align with ISO 55001 as a reference framework without pursuing formal certification, meaning the standard's influence extends considerably beyond the certificate count.
New Zealand ISO 55001 certifications: an updated picture
As at March 2026, at least thirteen New Zealand organisations hold active ISO 55001 certifications, three more than at August 2023, and across a broader range of sectors.
Eleven organisations appear on the JAS-ANZ public register. Two further certifications sit outside JAS-ANZ, including one under the UK Accreditation Scheme (UKAS) and one under the IAM Endorsed Assessor scheme. This is a useful reminder that the register, while the most reliable single source for New Zealand, is not exhaustive. The ISO Survey 2024, which draws on data from accreditation bodies globally, records 15 certificates and 35 sites for New Zealand, broadly consistent with the thirteen named organisations identified here, with the small remaining gap likely reflecting certifications issued through international bodies not routinely searched.

Several observations are worth discussing. The sector spread has widened: transport, water and wastewater, and electricity generation are all now represented alongside electricity distribution, facilities management, and defence, bringing the total to six sectors. Several organisations holding a certification, including Downer, Babcock, P2W Services, Transdev Wellington, Veolia, and PowerNet, are contracted service providers, reflecting the standard's relevance to both infrastructure owners and the service providers they engage. All but one certification is against ISO 55001:2014. KiwiRail's February 2026 certification is the first in New Zealand against the revised 2024 edition. Organisations holding 2014-edition certificates will be considering transitioning over the next three years. Some certifications have an extensive scope covering the full extent of the organisation’s primary assets. Others, like Kiwirail’s are restricted to a specific portfolio.
The true count of certified organisations is almost certainly higher than thirteen: certifications through non-JAS-ANZ bodies will not appear in the register unless separately disclosed, and some certifications covering New Zealand operations are held under Australian entity scopes.

Electricity distribution
The electricity distribution sector remains the most mature adopter of the ISO 55000 standards in New Zealand, and the 2026 AMP disclosure round provides the most comprehensive evidence of how that maturity has developed. Four distributors hold ISO 55001 certification directly: Unison Networks, WEL Networks, Horizon Networks, and Powerco. PowerNet holds certification with a scope covering the multiple electricity distribution networks it manages.

The most significant trend is the growth in networks being managed under ISO 55001 certification, from 0% in 2016 to 30% in 2026. This includes both distributors that have achieved certification directly and those whose networks are managed by a certified network management services provider. Awareness and intent to align have also grown steadily, with 81% of distributors now referencing ISO 55001 and intending to align their asset management systems with the standard. Perhaps most significantly for future certification growth, 63% are now actively aligning and 33% intend to certify, suggesting the certified proportion is likely to continue growing through the next AMP cycle.
The Commerce Commission's Asset Management Maturity Assessment Tool (AMMAT), derived from PAS 55 (the predecessor of the ISO 55000 standards), continues to be the primary formal driver of asset management system development in the sector. AMMAT has created a strong foundation of asset management practice from which ISO 55001 alignment and certification can develop, and the data suggests it is doing so at an accelerating rate.
Transport
Three organisations now hold ISO 55001 certifications in the transport sector: Transdev Wellington, P2W Services, and KiwiRail. Transdev Wellington's certification covers rolling stock, depots, and related assets for Greater Wellington train operations. P2W Services is certified for asset management of the Puhoi to Warkworth motorway under a private finance contract. KiwiRail achieved certification in February 2026, with a scope covering major equipment used primarily to support rolling stock maintenance. KiwiRail's certification is also significant as the first in New Zealand against the revised ISO 55001:2024 edition, rather than the 2014 edition held by all other currently certified organisations.
All three certifications are scoped to specific asset classes or contracts rather than being entity-wide, reflecting how certification is often pursued in large organisations: typically starting with a defined, manageable scope with the intent to extend over time. Beyond certified organisations, there are signs of growing engagement with systematic asset management practice across the sector. At the 2026 Transportation Conference, representatives emphasised the importance of improved asset management in the transport sector.
Water and wastewater
Veolia Water Services (ANZ) became New Zealand's first certified organisation in the water and wastewater sector in November 2023, covering the Wellington regional wastewater treatment plants under contract to Greater Wellington Regional Council. The certification is held by Veolia as service provider; no water utility owner-operators are currently certified.
The water sector is undergoing significant structural change under the Local Government (Water Services) Act 2025, which establishes economic regulation by the Commerce Commission following the model applied to electricity distribution. If information disclosure requirements develop analogously to those in the electricity sector, the incentives for water utilities to align with ISO 55001 could increase. Watercare, Tiaki Wai (the water services organisation being established for the Wellington region to succeed Wellington Water), and other major utilities are the most likely candidates to lead adoption in this sector.
Government
The ISO 55000 standards are seldom referenced in the infrastructure strategies and asset management plans of New Zealand's local authorities, with the International Infrastructure Management Manual (IIMM) remaining the dominant framework. Some councils are beginning to engage with ISO 55001 more explicitly in their improvement programmes. Kāpiti Coast's 2024–54 Infrastructure Strategy, for example, commits to developing a Strategic Asset Management Plan (SAMP) consistent with ISO 55001, but this remains the exception.
Te Waihanga's December 2025 Asset Management and Investment Planning Guidance is the most significant recent development in this space. Although aimed primarily at central government, it aligns with ISO 55000 principles and is relevant to local authorities. Te Waihanga has noted that New Zealand ranks near the bottom of the OECD on public-sector asset management maturity: as of June 2025, four of eight capital-intensive central government agencies lacked current asset management plans, and a further four reported asset registers that did not meet required standards. The guidance does not mandate ISO 55001 alignment, but its principles are consistent with the standard, and its adoption by central government agencies could provide a meaningful pathway toward broader engagement with ISO 55001 across the public sector.
Finding your peers: the visibility challenge
One practical purpose of research like this is to help organisations working on ISO 55001 to identify others on a similar journey and share experience, whether they are newly certified, mid-implementation, or still deciding. In a small country, peer learning of this kind can accelerate capability development considerably.
That peer visibility is currently limited. In the electricity distribution sector, the Commerce Commission's AMP disclosure regime provides a useful public record of where each distributor stands on ISO 55001. This is one of the less-noticed benefits of the disclosure regime.
Beyond EDBs, the picture fragments considerably. The JAS-ANZ register captures most certified organisations, but as this article illustrates, it does not show the full picture. Some organisations are certified under UKAS or other international accreditation schemes, and Australian-scoped certifications covering New Zealand operations fall outside routine register searches. For organisations that have not yet achieved certification, including those building their asset management system, working through a gap analysis, or weighing up whether to pursue formal recognition, there is effectively no public visibility at all.
Sector bodies such as Āpōpō, IPWEA, the Asset Management Council New Zealand Chapter and the Electricity Engineers’ Association are best placed to bridge this gap. A shared forum specifically focused on ISO 55001 implementation experience in the New Zealand context could add significant value.
We encourage any organisation working on ISO 55001 alignment or certification to get in touch. We are maintaining an ongoing picture of the landscape and welcome contact from organisations at any stage of the ISO 55001 journey.
Emerging drivers of demand
Four developments stand out as likely to shape ISO 55001 uptake in New Zealand over the coming years.
ISO 55001:2024 strengthens requirements across several areas relevant to New Zealand infrastructure organisations, and KiwiRail's February 2026 certification demonstrates that the transition to the new edition is already under way.
Water services economic regulation is the most significant potential new driver. Modelled on the Part 4 Commerce Act regime for electricity, the Commerce Commission's role in regulating water services could create incentives for water utilities to align with ISO 55001. As a regulated entity, being able to demonstrate ISO 55001 conformance is a powerful validation of prudent asset management and risk management.
Te Waihanga's December 2025 Asset Management and Investment Planning Guidance, if supported by meaningful monitoring and accountability, could catalyse uptake among central government asset owners who have to date been absent from the certification landscape.
ISO 55011, a recent standard in the ISO 55000 family providing guidance on developing public policy to enable asset management, is also directly relevant to New Zealand's policy context. Regulatory frameworks have been the most powerful driver of ISO 55001 adoption in New Zealand to date, and ISO 55011 provides a structured basis for extending that policy influence into sectors where it is currently absent.
Conclusion
As at March 2026, at least thirteen New Zealand organisations hold active ISO 55001 certifications across six sectors, up from ten across five sectors in 2023. The ISO Survey 2024 records 15 certificates and 35 sites for New Zealand, suggesting a small number of further certifications not yet publicly identified. The electricity distribution sector remains the most mature adopter with five certifications. Transport has emerged as the joint second-largest sector by certification count, with three certified organisations. KiwiRail's February 2026 certification is the first in New Zealand against the revised ISO 55001:2024 edition.

What remains absent is meaningful ISO 55000 engagement in the local government sector, where most infrastructure asset owners sit, and in the central government estate, where Te Waihanga has documented a significant maturity deficit. The conditions for broader uptake are however improving: water services economic regulation, the Te Waihanga asset management guidance, and the transition to ISO 55001:2024 all create new incentives and expectations. Across all sectors, the lack of visibility into who is working on ISO 55001, whether certified, in progress, or considering it, limits the peer learning that would accelerate capability development. Better visibility is in everyone's interest, and addressing it is something sector bodies, regulators, and organisations themselves can all contribute to.
