New Zealand’s infrastructure challenges are not new. What is new is the growing willingness to name their underlying cause: the persistent failure to manage the assets we already own in a systematic, value-focused way.
Against that backdrop, the release of the New Zealand Infrastructure Commission – Te Waihanga’s Asset Management and Investment Planning Guidance in December 2025 is a welcome and overdue development. It represents one of the most serious attempts in decades to elevate infrastructure asset management from a compliance driven exercise to a core public‑value discipline. If implemented well, it has the potential to reshape how central government plans, funds, and cares for public infrastructure. While aimed primarily at central government agencies, it will also be highly relevant to local authorities and other public asset owners.
Guidance alone, however, will not fix leaky hospitals, ageing water networks, or failing transport corridors. Whether this document becomes a genuine turning point, or another well‑intentioned report will depend on the extent to which leaders are prepared to change behaviour, incentives, and expectations across the system.
Te Waihanga and Ministers have been unusually candid in diagnosing the problem: New Zealand is near the bottom of the OECD in public‑sector asset management maturity. Agencies regularly report non‑compliance with existing Cabinet requirements: incomplete asset registers, unreliable condition data, and asset management plans that are out of date or poorly connected to funding and investment decisions.
The consequences are visible across the country. Maintenance is deferred to protect short‑term budgets, only to re-emerge as emergency renewals at a far higher cost and risk. Investment decisions consistently favour new projects over maintaining existing assets, despite Te Waihanga’s own estimate that for every $40 spent on new infrastructure, around $60 should be invested in maintenance and renewal.
What distinguishes this guidance from earlier frameworks is that it is not written solely for asset managers or technical specialists. It is explicitly directed at Chief Executives, Boards, and Ministers, recognising that asset management outcomes are shaped primarily by leadership decisions.
The guidance sets out:
- Clear expectations for integrating asset management with investment planning and budget processes
- A strong emphasis on reliable data, performance visibility, and service outcomes, not just engineering metrics
- Alignment with international best practice in whole‑of‑life and value‑for‑money decision‑making, consistent with ISO 55000 principles
Crucially, asset management is positioned as a system function rather than a lifecycle add‑on. Decisions about maintenance, renewals, and new build are framed as part of a single continuum, rather than separate funding and governance conversations.
This is a significant, and long overdue, shift.
If taken seriously, the guidance could deliver three major improvements across New Zealand’s infrastructure system.
1. Better Investment Decisions
Requiring agencies to demonstrate that proposed investments align with robust asset management plans should help counter the bias toward politically attractive new projects and force a more honest comparison between renewal, optimisation, and expansion options.
2. Greater Transparency and Accountability
Consistent expectations for asset data, performance indicators, and long‑term planning will make it easier for Ministers, Parliament, and the public to see whether agencies are caring for what they own and the services they provide.
3. A Shift in Culture
Perhaps most importantly, the guidance makes it clear that asset management is a leadership responsibility, not a delegated technical task. That alone has the potential to change how executives and boards engage with infrastructure risk, resilience and intergenerational equity.
However, there is a real risk that this guidance becomes another document agencies claim to follow without delivering meaningful change.
Asset management maturity remains uneven across the public sector. While councils face the challenges such as ageing infrastructure and constrained funding, in many cases local government asset management practices are more mature, supported by long‑standing audit and reporting requirements. However, in social infrastructure portfolios such as health, education and justice capability gaps are well recognised.
Many organisations lack the skills, systems and incentives required to meet the expectations set out in the guidance. Without stronger links between asset management performance and funding approvals, visible consequences for persistent under‑performance, and sustained investment in people, data, and systems the guidance risks raising expectations without enabling delivery.
The Comission has acknowledged this challenge, highlighting the need for capability development and a stronger “community of practice” to support implementation.
Te Waihanga’s guidance provides a clear roadmap. Whether it becomes transformative will depend less on what is written in Wellington, and more on whether leaders across the system are prepared to act on it.
If adopted broadly, the guidance could help bring greater consistency across New Zealand’s fragmented infrastructure system. It could also expose uncomfortable funding and capability gaps that central government will need to confront honestly.
