Police are continuing to receive an increased number of reports of suspicious approaches made to children in West Auckland this week.
On Wednesday a teenage girl reported to police she was asked to get in a man's car on Summerland Drive in Henderson.
Another girl, aged 17, complained to police that she had been followed by a ute in Lake Panorama Drive, also in Henderson.
The incidents follows the abduction and sexual assault of an 11-year-old boy who was walking home from the Ranui train station last month.
The man involved drove him back to Ranui and let him go.
Inspector Scott Webb said the increased reports are a result of increased vigilance in the community.
"We can however reassure the community that we are doing everything possible to ensure that all children and young people in this community are safe, and we are working closely with the victim of the Ranui assault as the search for the offender continues," he said.
