Water runs deeper than pipes and treatment plants in Aotearoa New Zealand. It carries memory, culture, and the weight of political choice. In recent years, water reform has become one of the country’s most contested public issues, binding together questions of affordability, community trust, Māori rights, and climate resilience.
From Havelock North’s Campylobacter outbreak to the rising seas of South Dunedin, the stakes are clear. When water fails, people’s health, livelihoods, and confidence in institutions are shaken. Reform has begun, but as Gillian Blythe, Chief Executive of Water New Zealand, stresses, the journey is far from straightforward.

Reform, trust, and contention
Few issues stir as much debate across councils, communities, and government as the future of water. A central reason for contention in New Zealand is the proposed shift from 67 council-delivered services toward a model that consolidates functions into 42 water service providers. While the aim is financial sustainability and regulatory compliance, the process has sparked resistance.
“The reform has been contentious for several reasons,” Blythe said.
“The previous government had proposed a mandatory amalgamation down to four entities. That included talk of economies of scale needing 600,000 to 800,000 people per organisation. For some communities, that was seen as forced change.”
Governance arrangements have also fuelled division. Early proposals for co-governance models unsettled parts of the public. Councils questioned what would remain if assets, staff, and debt shifted into new organisations.
“For some councils, what was left was something they weren’t comfortable with, and that’s why you’ve seen so much debate,” Blythe said.
The new policy, branded Local Water Done Well, allows councils to choose their path if they demonstrate compliance, sufficient investment, and financial sustainability. Yet even with greater flexibility, local government elections continue to see local candidates campaign fiercely on water.
Trust remains fragile, and Blythe argued that strengthening it will depend on open communication and clear safeguards.
“There is a need for no surprises,” she said. “If something is happening, elected officials cannot find out by reading it in the newspaper. Engagement and transparency are essential for rebuilding trust.”
Climate, affordability, and the infrastructure deficit
Behind the politics is an infrastructure deficit that has been decades in the making.
Pipes, treatment plants, and stormwater systems require urgent renewal. Climate change intensifies the strain, bringing rising seas, heavier storms, and more frequent floods.
South Dunedin, once marshland, is now a suburb under threat.
“With climate change, we are seeing groundwater levels rising and the impact of sea level rise,” Blythe said.
“Future scenarios show the flooding risks, and communities need to decide what path they want to take.”
Urban growth adds further complexity. As cities densify, demand for services presses against existing capacity.
Watercare’s recent capacity maps flagged areas where drinking water and wastewater networks are already under pressure, guiding developers toward locations where infrastructure can cope.
Affordability looms as the most significant challenge. Compliance with drinking water standards and environmental regulations requires investment running into billions.
“I don’t think we have fully grasped what affordability means,” Blythe said.
“When you start talking about thousands of dollars per household as a percentage of median income, not everyone will be comfortable. We have to keep charges down and deliver services more cost-effectively.”
A 2000 report, Ageing pipes and murky waters, warned that New Zealand’s water delivery model was no longer fit for purpose. The warning proved prescient.
For Blythe, whose career has been defined by structural and regulatory change, the question is no longer whether reform is needed but how to sustain it in the face of political headwinds.
Māori perspectives and community engagement
Water reform cannot be separated from Te Tiriti o Waitangi and Māori relationships with water. Treaty settlements for iwi such as Waikato-Tainui and Whanganui enshrine obligations that service providers must honour. The Whanganui River itself has legal personhood, requiring entities to treat it as a living being with rights and responsibilities.
“All councils have a Treaty obligation,” Blythe said. “Many iwi settlements include specific requirements around rivers. If you are a council-controlled organisation, you must uphold those obligations. Engagement with hapū and iwi is essential, both as Treaty partners and as neighbours.”
Mātauranga Māori, or Indigenous knowledge, is increasingly paired with Western science in water management. Blythe sees this blending of worldviews as critical to long-term resilience. Water New Zealand has made Te Wiki o te Reo Māori, Māori Language Week, a focal point, producing banners and resources celebrating the connection between language, culture, and water.
International perspectives enrich the journey. This year’s Water New Zealand Conference, combined with IWA-ASPIRE, featured Indigenous speakers from Canada and Australia. Nina Braid from Yarra Valley Water highlighted approaches to governance and resilience that echo challenges in New Zealand.
“We are on a journey,” Blythe said. “Councils and providers will need to continue building capability, respecting mātauranga Māori, and learning from indigenous governance models overseas.”

Lessons across the Tasman
Cross-Tasman exchange has already shaped reform. New Zealand utilities have drawn inspiration from Australian approaches to drought resilience, bushfire-impacted catchments, and large-scale utility governance.
“We’ve had several Australian chief executives speak at our conferences,” Blythe said. “Maree Lang, Anna Jackson, Nerina di Lorenzo, and David Ryan have shared insights on change management, resilience, and digital innovation. Their experiences managing large utilities are particularly relevant for us.”
At the same time, New Zealand offers lessons for Australia. Citizen assemblies and modular treatment plants are examples of innovation with broader relevance.
“Watercare did a citizens’ assembly to ask Auckland residents about the next water source,” Blythe said. “That kind of democratic engagement is something to consider looking at .”
Technology also features heavily. While almost two-thirds of New Zealand’s reticulated households have water meters, others do not. Wellington, for example, is only now debating whether residential properties should be metered.
For Blythe, greater use of metering, sensors, and digital twins will be essential.
“We need more sensors to detect pressure changes, overflows, and leaks, and digital tools to plan networks consistently,” she said.
The exchange is not one-directional but iterative, a reminder that both countries confront shared pressures from climate, cost, and community expectation.
The reform process is not short-term. Progress will be measured in decades, not election cycles. For Blythe, success will mean safer drinking water, reduced environmental impact, a skilled workforce, and greater water literacy across households. Yet the ultimate test won’t necessarily be technical: essential ingredients will be building trust between government, councils, iwi, and communities.
“We just have to keep going,” Blythe said. “If at first you don’t get all the way, you keep looking for opportunities to deliver safe drinking water, manage wastewater appropriately, and provide affordable services. Together, we can make a difference.”
