🏛️ Beyond Any Potential Savings: What You’re Actually Trading Away
The numbers on this page are modelled estimates - they will change as commercial terms are finalised. Some councils may see modest short-term savings from a CCO. But the financial case is only part of the story. The harder question is what you are permanently giving up in exchange for those savings.
Once a CCO is established and your water assets are transferred, the red flags, the unresolved disputes, and the unanswered questions that existed before the vote don’t disappear - they become the CCO board’s problem to manage, behind closed doors, under commercial confidentiality, without your vote. And unlike a council decision, this one cannot simply be reversed at the next election.
🏦 The Debt Shell Game - Explained Simply
Every council has a borrowing limit - think of it like a credit card limit set by the LGFA (Local Government Funding Agency, the councils’ specialist lender). When a council is near that limit, it cannot borrow more for roads, libraries, or anything else.
When water debt moves into a CCO, it disappears from the council’s books. The council’s credit card suddenly looks almost empty again - so it can borrow more. But the debt hasn’t gone away. It has just moved into a new company that ratepayers still own and are still ultimately responsible for. If the water company can’t pay its debts, who bails it out? The same ratepayers.
This is exactly what S&P Global warned about - calling it “contingent liability.” The council looks healthier on paper. The risk hasn’t changed. It’s just been made invisible.
🚰 Your Biggest Public Asset - Who Actually Owns It?
Water infrastructure - the pipes, treatment plants, reservoirs, and pumping stations under your streets - is almost certainly the single most valuable asset your council owns. In most NZ councils it dwarfs everything else: the libraries, the parks, the civic buildings combined.
As a council-owned asset
Your elected councillors control it. They can change direction. They can be voted out if they make bad decisions. The asset is governed by the Local Government Act, with public meetings and transparency requirements.
Inside a CCO
The council becomes a shareholder, not an owner. The board makes the decisions - and the board is not elected by you. Directors are legally required to act in the interests of the company, not the community. Decisions happen under commercial confidentiality, not in public meetings.

After a CCO
What you lose
Who actually sits on a water CCO board?
Under the Local Government (Water Services) Act 2025, CCO boards are made up of independently appointed directors - typically lawyers, accountants, infrastructure executives, and former council executives. Elected councillors do not sit on the board. They may hold shareholder seats (as the council's representatives), but the majority of governance decisions are made by the commercial board, not by people you voted for.
Established CCO Boards - What We Know (April 2026)
Five CCO boards have been established or announced. Only one has fully disclosed director fees.
| Entity | Councils | Board Type | Chair Fee | Director Fee | Total Board Cost | CEO Salary | Fees Disclosed? |
|---|---|---|---|---|---|---|---|
| New Plymouth Water Services CCO (WSCCO) | 1 council | Full CCO | $92,700 | $50,000 | $292,700/yr | - | ✅ Yes |
| IAWAI - Flowing Waters | 2 councils | Full CCO | - | - | Not disclosed | $395,000 | ❌ No |
| Central Districts Water (Shareholders Committee) | 4 councils | Shareholders Committee | $45,000 | - | Not disclosed | - | ❌ No |
| Selwyn Water Limited | 1 council | Full CCO | - | - | Not disclosed | - | ❌ No |
| Hawke's Bay Water Services (Advisory Board) | 3 councils | Advisory Board | - | - | Not disclosed | - | ❌ No |
Is this decision reversible?
Once a Water Services Delivery Plan (WSDP) is accepted by the DIA, Section 22 of the Local Government (Water Services Preliminary Arrangements) Act 2024 legally requires councils to give effect to it. The Minister for Local Government also holds intervention powers if councils do not proceed. In practice, once the CCO is established and assets are transferred, unwinding the structure would require legislation - it is not a decision that can simply be reversed at the next election.
⚡ What the Electricity Sector Tells Us
New Zealand's electricity sector followed the same path - and prices never came back down.
The water reforms are not happening in a vacuum. New Zealand has been here before. In the 1980s and 1990s, the government corporatised electricity - moving it from public ownership into State-Owned Enterprises and CCO-style structures, promising efficiency gains and lower prices. The same arguments were made: commercial discipline, professional management, economies of scale.
1980s
Corporatisation
Electricity moved from local bodies and the NZED into State-Owned Enterprises. Boards appointed, not elected. Same model as water CCOs today.
1990s
Commercialisation
Lines companies and generators separated. Prices began rising. Commerce Commission found persistent excess profits in the sector.
2000s
Partial Privatisation
Government sold minority stakes in Meridian, Genesis, and Contact Energy. Once assets were in commercial structures, the pathway to sale was straightforward.
Now
Result: Higher Prices
NZ household electricity prices rose ~150% in real terms between 1990 and 2020. The Commerce Commission's 2019 review found the sector had failed consumers for decades.
The price data - before and after corporatisation
~$0.06/kWh
Average residential electricity price, 1985 (inflation-adjusted)
~$0.32/kWh
Average residential electricity price, 2023
+430%
Real price increase since corporatisation - despite the promised efficiency gains
Why this matters for water
Water is a natural monopoly - just like electricity. You cannot choose a different water provider if your CCO raises prices. The Commerce Commission cannot regulate water prices the way it can electricity lines. And once water infrastructure is inside a CCO, the legal and political pathway to partial privatisation is significantly shorter than it was before. The question is not whether this will happen - it is whether ratepayers are being given enough information to make an informed decision before it does.
