Health New Zealand says some vape stores are putting profit over the health of our children.
In July, the agency sent underage volunteers to 600 stores to attempt to buy vape and cigarette products.
63 retailers were caught - and will face infringement fines.
National Public Health Service Compliance Manager Jo Pugh says it's very disappointing.
"As a result, we sent out more infringement fines of $500 in this month than we have ever before."
