The children have been placed in Child Youth and Family care and their parents are under investigation.
The children, whose ages ranged from five months to eight years old, were found in the van around 11am on Sunday morning.
SkyCity said their surveillance recordings indicated the children had been locked in the vehicle for about 45 minutes.
A couple returning to their car heard the children crying and notified SkyCity security staff.
Staff found the parents upstairs gambling in the casino.
The family was taken to Auckland central police station.
I’m sorry, but there is just no excuse for that. How can you leave a five month old alone without adults, let alone five kids?Tags: child abuse
