When I think about environmental management, I usually begin with a river.
Start in the mountains. Follow the water, gravel and sediment through braided rivers, groundwater systems, farms, towns, roads, bridges, drinking water supplies, wetlands, lagoons, and then out to the coast.
Along that path sit homes, marae, businesses, ecosystems and public infrastructure. Every decision connects to another. Land use affects water quality. Water allocation affects communities and production. Flood protection affects public safety. Climate change affects the whole system.
That is the reality local government reform has to deal with.
The environment does not organise itself around council boundaries. It organises around catchments, ecosystems, hazards and communities.
The obvious question: how will local government reform deliver for the environment? The answer is equally as obvious: by protecting the functions that actually manage the environment.
This is not about preserving current institutions. The environment does not care which institution holds the function. But it cares very much whether the function is done well.
The current regional council functions are not just another layer of local government. They are the main environmental regulatory functions in the system today: water, land, air, coastal resources, biodiversity, biosecurity, flood protection, regional transport, and emergency management. They also hold much of the science, monitoring data, compliance capability and catchment knowledge the new system will rely on.
In Canterbury, we manage around $900 million of flood protection and drainage assets, sitting behind communities, farms, roads, bridges and major aspects of our regional economy.
There is a legitimate case for better alignment. Communities do not experience land, water, transport, housing and hazards in separate legislative boxes. But more unitary authorities may create further tensions and gaps if boundaries aren’t at catchment scale.
Done well, the new system could reduce some duplication, improve spatial planning, and make environmental limits more visible in decisions about growth. That would be a good thing. But it is not automatic.
We should be real about the scale of the change. This local government reform is being described as simplification, but for many communities it is simply amalgamation: new boundaries, new accountabilities, and new risks during transition. It is being run to deadlines that appear to owe more to the political and legislative timetable than to environmental system design.
I understand why governments want speed. But speed creates the risk that the timetable starts driving the outcome, and it is the environment that lives with the outcome - for decades.
In my view, the new system has to pass five practical tests if it is going to deliver for the environment.
- Catchment integrity.
Water, sediment, nutrients, flood risk, pests and biodiversity do not stop at district boundaries. In Canterbury, mountains-to-sea is not a metaphor. It is how the place works. Decisions upstream have consequences downstream for decades. If new structures cut across catchments badly, the system looks simpler on paper but works worse in practice. We have made the mistake before of drawing lines down the middle of rivers. The map should follow the work and the risks, not the other way around.
- Regulatory independence.
A council that owns infrastructure, promotes growth, grants permits, monitors compliance and enforces against non-compliance faces real conflicts. Those conflicts can be managed, but they have to be designed for, not wished away. Recently, Canterbury Regional Council issued an abatement notice for unconsented wastewater discharges into Whakaraupō Lyttelton Harbour. Would a unitary do this to itself? In any future unitary structure, the public would need to see very clearly how that same regulatory independence would be protected. The public needs confidence the regulator can act without fear or favour, including when the non-compliant party is a council or a major public asset. That means clear statutory roles, separation of regulation from operations, and strong compliance and enforcement capability.
- Science and data.
This is public infrastructure, not back-office overhead. Environmental limits, freshwater allocation, flood forecasting, coastal hazards, biosecurity - all of it rests on long-term datasets and specialist people. Capability that is easy to disrupt and hard to rebuild. If reform scatters expertise or treats monitoring as a cost to trim, the new system starts with weak evidence and that leads to weak decisions. Clause 128 of the Natural Environment Bill is a useful warning sign. It raises the question of whether councils would be expected to make specialist wildlife decisions without the ecological expertise those decisions require. Whatever you think of the policy, it exposes a wider risk: functions being shifted without enough attention to capability.
- Mana whenua partnership.
Reform must not reset relationships. In Canterbury, Ngāi Tahu relationships are not a stakeholder workstream. They are central to how freshwater, biodiversity, coastal planning and hazards are understood and governed. Te Tiriti obligations, Treaty settlement arrangements and iwi management plans cannot be parked while institutions are rearranged. Mana whenua need to be at the table in a real and enduring way. If the structures change, the relationships do not start again from zero.
- Transition discipline.
We are not dealing with one change. We have local government amalgamation, resource management reform, Local Water Done Well, central government restructuring and more, all at once. Any one of these would be significant. Together, they create real system risk. Running them to tight, separate deadlines makes that harder, not easier.
Tight deadlines pull each work programme inward, toward its own timetable, and gaps open up between them. The environment lives in those gaps - in the connections between water and land, between hazard and growth, between one catchment and the next. During transition, rivers still flood, pests still spread, consents still need decisions and buses still need to run. That is why transition risk is environmental risk. We cannot afford a period where everyone is busy designing the future while the current system quietly loses capability and accountability.
Every reorganisation proposal needs to show how it protects catchment-scale management, regulatory independence, the science base, mana whenua partnership, and flood and emergency management capability through transition. That should be a condition of reform, not optional guidance.
The opportunity
Better integrated spatial planning could help New Zealand make clearer decisions earlier about growth, infrastructure, natural hazards, environmental limits, and resilience.
Reform can deliver for the environment, but only if it starts with the environment. Not with institutional tidiness. Not with a map of council boundaries. Start with catchments, hazards, ecosystems, communities, mana whenua rights and interests, and the functions that protect them.
The task is not to force environmental systems into a tidier institutional map. It is to design institutions around the systems we are here to protect. Designed that way, reform strengthens the system. Designed for speed and tidiness, it ends up simpler but less capable.
Let me be plain: on the current drafting and timeframes, this reform is at real risk of falling short on several of these tests - through haste, not intent.
There is still time to get it right while the design is moving.
Let’s take it – and make sure local government reform delivers for the environment.
