Queenstown police are hoping CCTV footage will help them identify a stranger who offered a lift to a Shotover Primary School pupil last Thursday.
Sergeant Simon Matheson said inquiries were continuing.
"We will also be looking to work with the school to ensure the safety of all students," Sgt Matheson said.
Acting principal Evelyn Aurik took to the school's social media page last Friday to alert parents that a child "reported that they were approached and offered a lift by someone they didn't know".
Last week, police said a 7-year-old girl was approached outside the school about 2.55pm. No other children were nearby.
A man asked her if she wanted a ride and she replied she was waiting for her father.
The girl described the man as Asian, tall and skinny and the car as a four-wheel-drive.
Parents are being advised to talk to their children about stranger danger, and children waiting to be picked up should stay in a group or inside.
Ms Aurik told the Otago Daily Times she had no further details.
