POLICE have requested public assistance in relation to three similar incidences where children have been approached in the Camden Haven area.
Each occasion a blue hatchback sporting red P-plates has been put at the scene.
Mid-North Coast Local Area Command crime manager Detective Inspector Steve Clarke said he was concerned at the reports and police were working hard to locate the vehicle of interest and its driver.
"There is a reason for concern at these reports," Det Insp Clarke said.
"We are asking all parents and residents to stay vigilant and keep an eye on children in the area."
Det Insp Clarke said the latest incident occurred on Wednesday at Lake Cathie - it is the third such event in the area this month.
Previously on January 8, two girls were walking along Kew Road when they saw a car parked adjacent to a block of units.
A man sitting inside the driver's seat of the vehicle called out to one of the girls, a 16-year-old, offering her an amount of cash to get into his car.
When she declined, he drove off in an unknown direction.
On Tuesday earlier this week another 16-year-old girl was involved.
The teenager was riding a skateboard along Abel Tasman Drive when the vehicle in question stopped a short distance from her.
Police said the driver tried to coax the girl into the vehicle but she fled the scene.
Police are still conducting investigations into the Wednesday incident which happened in Lake Cathie.
Det Insp Clarke warned youngsters in the area to also be aware of the situation and offered advice if caught in a similar circumstance.
