The impact of a rates cap is hard to predict until all the pieces of the reform puzzle are on the table Ashburton’s mayor says.

The government's long-awaited rates cap announcement was for a variable target band of between 2-4%, excludes water charges, and would be enforced by a new regulator.

But there is plenty of detail still to work Ashburton Mayor Liz McMillan said.

“The rates capping was announced this week, but we don’t yet know the detail of the Resource Management Act reform and its impact on regional council and district council functions and responsibilities.

“There is significant change being proposed for local government and it’s not yet clear how all the moving parts will fit together.

“Given all that, it is too hard to say what the impact will be, but it will definitely start to become much clearer in the coming weeks and months.”

The early signals from the Government earlier this year were that the cap would exclude critical infrastructure – roading, water and waste services.

Instead, the only exclusion is water charges.

The Government aims for the cap to take effect from January 2027, with a full regulatory regime in place by July 2029.

Selwyn Mayor Lydia Gliddon also wants to see more details on rates cap, and how it fits with the other Government reform.

“If the policy is designed well, it can deliver real benefits for families while still allowing councils to maintain essential services,” Gliddon said.

“Our focus is on constructive engagement with central government to ensure any changes reflect the realities of fast-growing districts like Selwyn.

“Affordability is important, and we understand why households want cost relief.

“At the same time, councils must maintain roads, water assets, parks, libraries, and other critical infrastructure.”

Overseas examples show poorly structured caps can lead to ageing infrastructure and higher repair costs later, “so practicality depends on getting the balance right”.

What cuts or fee increases the council could be forced into to make the 2-4% cap work is one of the key questions to work through she said.

“The cap doesn’t apply to fees and charges, so councils may look at alternative revenue streams.

“But our priority is protecting essential services and long-term sustainability, not short-term fixes.”

Last week it was a local government shakeup, this week a rates cap and next week it is tipped the first look at the new Resource Management Act is set to drop in council inboxes.

Gliddon said that “once we understand the implications, including what the Resource Management Act reform will look like, we’ll keep the community informed, because we want what’s best for Selwyn and the wider region.

"This is a significant opportunity to contribute to the future direction of local government for communities throughout the region, and I look forward to getting to work."

To support well-informed input into the consultation process, a two-day briefing workshop will be held in January, giving councillors the opportunity to work through the detail and shape Selwyn’s position ahead of the February submission deadlines Gliddon said.
