The lowest network charge for adults presently was Massey Park, Papakura, which charged $3.10 entry.
Adult charges at the region's pools range from $5 to $6 and $6.90.
Charges would still apply to all for entry to spas, saunas, hydra slides, diving boards, steam rooms and to use special play equipment.
Entry would be free for school groups to book space on school days between 9am and 3pm and for children's groups during standard hours.
Councillors were told the kids-free policy would not apply to Newmarket Pool, where the lessee sets fees and charges, or to facilities where the council is a partner but does not set the prices.
South Auckland councillor Alf Filipaina was concerned that an adult care giver for a disabled adult would have to pay. He was told it would be at a disability rate of less than $3.10.
An adult supervising a child would be classed as a spectator and pay the lowest network price, which might be $1.
Councillor Ann Hartley said it would be of concern if no concession was made for older people where pools did not currently offer a discount. It was stated that local boards were able to put in their own money to subsidise disabled or older people.
Officers said the council was trying to strike a deal with trusts in Mt Albert and Mt Eden to allow children 16 and under to swim free, but they would need compensation.
Auckland has 24 pools and three more are to be built in the next eight years - at Otahuhu, Albany and Ormiston.
