"The police have been notified and are dealing with the situation."
Hughes said the school was taking the matter "very seriously" and had discussed some steps to take "if a driver stops and asks you for directions" or you think someone is following you, with the children on Friday.
"We would strongly recommend that you also discuss them with your child at home," Hughes said.
The school has also warned other schools in the area of the incident.
Police are treating the incident as suspicious at this stage. Officers have spoken with the boy and staff at the school.
There have been similar reports in the past few months outside schools in the west of the city.
An 11-year-old boy was abducted and sexually assaulted in Ranui in November.
Police said a man in a grey van asked the boy for directions before driving him to an unknown location and sexually assaulting him. The boy arrived home four hours later.
Six days later, on November 23, an 11-year-old girl reportedly fled a man driving a dark red or maroon four-wheel drive while she waited for a school bus on Wairere Rd, Waitakere.
The next day, a man asked two 12-year-old boys walking home from school to get in his dark-coloured ute on Swanson Rd in Ranui.
An intermediate-aged girl was also asked to get into a stranger's vehicle on Summit Dr in Henderson in December.
