SkyCity has an internal carpark.
Mr Kennedy said he thought the fact car parking in Wanganui was predominantly street-based meant it was less likely parents would leave their children alone in cars.
He said a bigger problem for most cities would be with children left home alone while their parents were away gambling.
Problem Gambling Foundation spokeswoman Andree Froude said the situation exemplified the fallout from problem gambling.
The urge to gamble could be so great that people made decisions they would not consider making under normal circumstances.
She said it was an unfortunate reality that children could become the victims of their parents' gambling issues.
Child, Youth and Family central regional director Tania Harris said the police were normally the first to be alerted to children being left unsupervised and they ensured the immediate safety of the children.
Child, Youth and Family (CYF) then worked with the family to develop a plan to ensure the children's future safety.
Ms Harris said it was not uncommon for CYF to be alerted to situations where children were left unsupervised in cars for lengthy periods.
"In addition to the obvious safety risks, children left in a car can easily get frightened or distressed," she said.
