Successive governments have claimed crack downs on youth vaping but retailers are flouting the law, with just one prosecution on the books.

Associate Health Minister Casey Costello accepts compliance figures are not good for underage sales or illegal products, and says says she's "driving really hard" to "push enforcement" but this will take time.

Vapes, or e-cigarettes, were introduced as a smoking cessation tool - and while New Zealand's smoking rate has now fallen to historic lows, 16 percent of children aged 14 to 15 were regularly vaping last year.

While that's down 2 percent from 2022, it's a worry for many parents including Wellington mum Charyl Robinson, who says her eldest son is "hopelessly addicted" and went through withdrawals during pandemic lockdowns. She says it fractured relationships in the household, with outbursts, rage, violent behaviour: withdrawal symptoms amplified because young people are not equipped to deal with it.

Robinson teamed up with other mums throughout the country to set up Vape Free Kids NZ - an advocacy group fighting for tougher regulations - and while regulations have been tightened up, she says the fight has become "immeasurably harder" since the coalition came to government.

Associate Health Minister Casey Costello says it's "ridiculous and wrong" to say the tobacco industry has anything to do with her government's policies.

"Increased penalties need legislative change .... what I'm trying to do is as much as I can under this period, but right now we can do a lot around education and enforcement.
