There are renewed calls to outlaw smoking in cars after a new study highlights the prevalence of the problem.
A study by Auckland and Otago universities concludes we're failing our obligation under the United Nations Convention on the Rights of the Child, by not protecting them from secondhand smoke.
Hapai Te Hauora Chief Executive Lance Norman said told Mike Hosking the study shows an overwhelming majority of New Zealanders want the ban.
"94 per cent of adult non smokers and surprisingly 89 per cent of smokers are in favour of banning smoking in cars with children."
Calls for the government to legislatively protect children from breathing in second-hand smoke in cars.
A study by Auckland and Otago Universities shows an overwhelming majority of both smokers and non smokers support banning smoking in cars with children.
Norman said there's a right and wrong way to go about enforcing an ban.
"You don't want that to be a go to jail law or an instant fine, you want it to be as positive 'here's a warning, here's a public health message about smoking'. You don't want to victimise families that are probably already struggling."
