A survey of more than 30,000 of New Zealand’s Year 10 students shows that the number of teens who vape regularly has dropped by half since it's peak in 2021. 

The number of teenagers who vape on a daily basis has also dropped from “peak vape” of 10.1% in 2022, to 7.1%.

Auckland Grammar headmaster Tim O'Connor says he has noticed the shift but doesn't know what it can be attributed to.

"I don't know what's going on to tell you the truth. I don't know whether it's us being more effective, or the messages happening, or if it's just random," he told Heather du Plessis-Allan.
