Britain's water sector is undergoing one of its most significant resets in a generation. The consequences of decades of underinvestment, fragmented governance and deferred maintenance are now playing out in polluted waterways, repeated flooding and growing public scrutiny.
New Zealand is at a different point, but the conditions are not unfamiliar. Ageing assets, rising climate risk, complex governance arrangements and evolving community expectations are all present.
Stormwater sits at the intersection of these challenges, spanning land use, transport, environmental health and climate resilience.
Drawing on his analysis of the UK experience, Technical Director Pete Brooks outlines five lessons for Aotearoa's water sector, covering accountability, catchment-scale planning, asset management, social licence and the role of nature-based solutions.
Across the Tasman and beyond, the consequences of underinvesting in water infrastructure are playing out in real time.
While the conditions that led to Britain’s water crisis are familiar, the opportunity still exists for Aotearoa to shape our water sector outcomes rather than simply respond to failure.
Stormwater is one of the most obvious areas to drive this change. At the intersection of land use, transport, environmental health and climate resilience, stormwater management reflects the full complexity of water reform. Get it right, and the benefits compound. Get it wrong, and the costs – financial, environmental and reputational – will be substantial.
Drawing on my analysis of the UK's experience, I see five lessons that Aotearoa's water sector cannot afford to overlook.
The instinct in water reform is often to reorganise. But structural change without clarity of roles and responsibilities rarely delivers the intended outcomes. The UK's experience shows that durable improvement comes from defining who is accountable for what, ensuring those accountabilities are funded and enforceable and holding the line when it matters. Aotearoa's reform process offers an opportunity to get this foundation right from the outset.
Effective stormwater management requires thinking at the scale of the catchment, not the council boundary. Integrating land use, transport and environmental planning within a coherent catchment framework is not just good practice, it is essential for managing flood risk, improving water quality and building long-term resilience. The UK learned this through costly fragmentation. We can choose a different path.
The most effective stormwater outcomes we see globally are place-based, partnership-driven and anchored in nature.
Long-term resilience starts with understanding what water infrastructure assets you have and their condition. Publishing asset health baselines, linking them to credible renewal pathways and applying adaptive management approaches that respond to both performance data and climate risk thresholds are foundational steps. Transparent reporting on asset condition also builds trust with communities and regulators alike.
It demonstrates responsible investment management and transparent risk understanding.
Public support for water infrastructure investment is not guaranteed. It must be built and maintained. Customer charters that translate technical standards into clear service commitments, public dashboards that track progress on flood risk reduction and environmental outcomes and accessible, fair complaints processes all contribute to a credible social contract with communities. In a sector where long-term investment relies on sustained public confidence, visibility is not a communications exercise. It is an operational imperative.
The most effective stormwater outcomes we see globally are place-based, partnership-driven and anchored in nature. For Aotearoa, this means genuinely embedding iwi and hapū perspectives in catchment-scale decision-making, not as a consultation step, but as a design principle. It also means defaulting to nature-based solutions wherever possible, working with natural systems to deliver outcomes that are more resilient, more cost-effective and more valued by communities.
Britain's water reset was not chosen; it was forced by a system at breaking point. The result is reactive, expensive, and ongoing.
Aotearoa has a different opportunity. The conditions for meaningful, proactive reform are present: a sector aware of its challenges, communities with rising expectations and a policy environment in motion.
Closing the gap between intent and outcome demands integrated planning across environmental, asset, customer and financial considerations, alongside transparent performance reporting and genuine partnership with communities and tangata whenua.
This is where Aurecon's water expertise makes a difference. We partner with you to navigate reform through evidence-based asset management, catchment-scale planning and nature-based solutions that build long-term resilience.
The lessons from the UK are available. Acting on them now, before the system reaches breaking point, is the difference between a trusted, resilient, fit-for-the-future water sector and one that is simply catching up.

The economic case for integrated asset and investment management in New Zealand and how well-governed infrastructure delivers lasting cross-sector value.
As climate risks intensify, New Zealand must adopt nation-wide resilience planning that connects infrastructure, leverages data, and empowers communities.
From water pricing to water management systems, lessons from Australia can guide water utilities through New Zealand's transition to 'Local Water Done Well'.
