"I support making pools free if the cost isn't too high, but I want to hear people's thoughts on the fairest option for the whole region given there are differences in pools provision depending on where you live.
"Free pools are a massive success in South Auckland where they help kids learn to swim and keep them healthy and active," Mr Brown said.
But councillor Cameron Brewer said no one would believe that universal free entry to the region's 24 pools would cost $5.5 million when it cost $6.7 million to provide six free pools in Manukau.
Mr Brewer said it was disingenuous to put the $5.5 million figure in the draft budget for public consultation.
The KPMG report was rushed, incomplete and undercooked the costs, he said.
"I'm concerned that many will see the $5.5 million figure, which equates to less than $5 per Aucklander, and demand universal free access. However, the Manukau experience shows it's going to be miles more expensive and the public should have been given an honest and realistic cost to consider," Mr Brewer said.
Making all 24 swimming pools free would increase demand and costs, such as the need for bigger changing facilities, carparks, maintenance and more staff, he said.
KPMG said it had only enough time to base its figures on six swimming pools.
GATES OPEN
Aucklanders can have free swimming pools for $5.5m so long as:
