Havelock North parents and students have been sent a message from principals to be aware of stranger danger, after local police issued several reports concerning children being encouraged to enter a vehicle.
Te Mata Primary School principal Michael Bain said police had come to see him and other school principals on Monday.
"A group of kids were approached on Friday when they were participating in cross-country," Mr Bain said.
"Since then there has been a child approached on Monday and one on Tuesday morning."
The child who had been approached yesterday morning was a student at his school.
