May 2026 Update: A Turning Point for Far North Water Infrastructure

May has been a monumental month for water and wastewater infrastructure in the Far North. We have seen a groundbreaking technological success in our communities, alongside major political shifts that will define our district's financial and environmental future for decades.

As a trust dedicated to sustainable, affordable, and climate-resilient solutions, we have been working tirelessly on the ground and behind the scenes. Here is a summary of the latest developments and what they mean for you as a ratepayer and resident.

1. The Solution in Action: Rāwene EC Plant Commissioning

The highlight of the month was the official commissioning of the Electrocoagulation (EC) Wastewater Treatment Plant in Rāwene on May 9th. Hosted by Te Mauri o Te Wai and attended by regional leaders, the event was a resounding technical and cultural success.

• The Results: The plant successfully treats 6.5 cubic metres of wastewater per hour, transforming it into clear effluent and settled flocculation in just 10 minutes, effectively destroying pathogens without the massive footprint of traditional biological plants.

• Powered by the Sun: To ensure true carbon neutrality and low operating costs, a 64 kW solar array will be installed uphill to support the plant.

• Cultural Alignment: This technology finally offers a realistic pathway to achieving the hapū mandate of "zero waste to wai," turning waste into a resource for land-based application rather than discharging it into our precious harbours.

2. The Political Shift: FNDC Joins Northland Waters Limited (NWL)

On May 20th, the Far North District Council (FNDC) held an extraordinary meeting and officially voted to join the new regional water company, Northland Waters Limited (NWL).

• The Ratepayer Risk: While this transition promises regional collaboration, we have scrutinised the fine print. Under the new constitution, Far North water debt is "ringfenced" for at least the next 3.5 years. This means Far North ratepayers will directly bear the cost of the $49.4 million wastewater capital works programme currently proposed in the 2026/27 Annual Plan.

• Our Advocacy: We are actively warning that borrowing $49 million to build outdated, massive biological plants—some of which are projected by consultants to still struggle with compliance by 2031—is a financial trap. We must pivot to affordable, modular solutions like the Rāwene EC plant before this debt is locked in.

3. The Looming Crisis: Kerikeri’s Infrastructure Bottleneck

Our team has recently completed a deep dive into the Proposed District Plan (PDP) Hearings Commissioners’ Reports. The reports highlight a dangerous disconnect:

• The PDP-R would enable massive new housing intensification across Kerikeri.

• However, our analysis of engineering reports shows the Kerikeri Wastewater Treatment Plant is already routinely exceeding its safe operating capacity, especially during rain events, resulting in poorly treated discharges into the sensitive Waitangi wetlands.

• Because major upgrades for this plant are not funded to be operational until 2031 at the earliest, the town faces an infrastructure bottleneck. We have been briefing the Northland Regional Council (NRC) and FNDC leadership on this impending crisis, advocating that rapid, modular EC technology is the only viable way to bridge this gap and prevent a building freeze.

4. Next Steps: Shaping the "Statement of Expectations"

The fight for affordable, clean water is now about shaping the rules of the new CCO. FNDC has appointed Mayor Moko Tepania and Cr John Vujcich to the Shareholders' Representative Group (SRG), with Crs Arohanui Allen and Kelly Stratford as alternates.

Over the next six months, they will help draft the Statement of Expectations (SoE)—the ultimate rulebook for the new water company.

Our Goal: We are actively supporting our SRG representatives with data and analysis, urging them to ensure the SoE includes binding requirements for:

1. Affordability: Protecting ratepayers from massive legacy debts.

2. Zero Waste to Wai: Mandating a transition to land-based wastewater disposal.

3. Smart Innovation: Prioritising modular, solar-powered, and decentralised technologies.

Thank You to our supporters. Transforming outdated, multi-million-dollar infrastructure plans is not easy, but the success at Rāwene proves that a better, cheaper, and greener way is possible. Thank you to the community groups, hapū leaders, and technical experts who continue to collaborate with us.
