The proposed reform means management of drinking, waste and stormwater systems would shift away from individual councils and into the hands of four regional authorities.
It has been met with scepticism from many councils, including pockets of the South.
Between drinking and environmental standards — and allowing for population growth — the Government calculates between $120billion and $185billion needs to be invested.
But a common sentiment is shared by southern mayors following the end of a two-month engagement: they are none the wiser whether they want to join or not.
He also understood the status quo was not going to work for his region.
"In that respect, we understand where the Government is coming from," he said.
However, Hicks also believed the Government had some work to do, particularly regarding the structure it has proposed.
One of the main issues his council faced was disseminating dense data that made it difficult to ascertain outcomes.
"Along the way, we've said the Government haven't given us enough information.
"Actually, as I sit back and reflect on that, they've given us a whole lot of information. In some ways, they've given us too much information."
Hicks said the pipes in all local authorities had been under-invested in for about 60 years, and believed it was in part due to the invisibility of the infrastructure.
"There's millions of dollars of assets sitting there but you can’t see them.
"The only connection you have with those assets is when you turn the tap on and water comes out, or you flush the toilet and water goes away."
Cadogan was critical of councils that had already opted out, saying it tarnished public opinion and made it difficult to have discussion on the issue going forward.
"We felt it was an absolute insult to our communities that we make a statement before we know what the final proposal is," he said.
"We can’t get to that step until it goes to Cabinet next week."
Local Government Minister Nanaia Mahuta has indicated change is coming, whether councils like it or not.
Mahuta said the Government had taken onboard feedback, but wished to reaffirm the status quo would not continue.
"With the passing of the Water Services Act earlier this week, monitoring and enforcement of compliance will increase — communities will not have to put up with second rate water services," she said.
Councils had until Thursday to make submissions.
"To date, it would be fair to say we don’t have sufficient information to make a decision," he said.
"And we hope to get that [information] in the next few weeks from the minister."
Talking on Thursday, Tong said Otago and Southland councils had indicated they would opt out based on the current information they had, a sentiment he believed was echoed throughout the country.
He was not afraid the council would lose assets by joining the scheme, acknowledging that water systems were also a liability.
In her response to Local Democracy Reporting, Mahuta also made that clear.
There had been serious underinvestment in the infrastructure, and to claim it was an asset "might be an overstatement", she said.
Now Shadbolt has indicated he is skeptical, too.
"It's hard to know where Auckland is going to go, and some of the [other] big players. That will have a profound effect," Shadbolt said.
"It's been pretty consistent, the answer to everything has been ‘well we don’t know’, ‘we need
more consultation’, ‘give us the data’."
Shadbolt believed the Government had a mandate to push the proposal through irregardless of council opposition.
On Tuesday, the Queenstown Lakes District Council held an extraordinary meeting to discuss its response, and Mayor Jim Boult described the reforms it as a "hospital pass".
With the two-month consultation period now complete, Mahuta is now taking feedback back to Cabinet.
She said the Government had been clear the new entities would be collectively owned by councils within their multi-region entity, and the assets would continue to service their existing communities.
"Continued public ownership of our water infrastructure and services is a bottom line for the Government and we are developing safeguards against future privatisation.
"The challenges facing our water system and services have been around for more than two decades and we need to address them now."
Cabinet will consider the next steps for the reforms once a final report has been constructed, including a process for public consultation.
