Ms Gordon said the van had been reported stolen from Palmerston North several days earlier.
It's alleged the occupants had been on a crime spree, involving a theft in Napier and petrol "drive-offs" in the Sanson area.
Ms Gordon said the teenagers were from the Palmerston North and Feilding areas and had been sleeping in the van during their trip. All 11 were taken to Levin police station and their parents contacted to collect them. Two were released into Child Youth and Family care.
Ms Gordon said inquiries were continuing and the files would be referred to Youth Aid for follow-up action. The 18-year-old will appear in Levin District Court next week.
She said it was a reminder for parents to check where their children were.
