Sorry, but that won't work.
Smokers can be a stubborn bunch and unless you legislate, they won't change.
In August Mrs Turia said she wanted to make smoking in cars with youngsters on board illegal as New Zealand steered towards being a smokefree country by 2025. She said she wanted that first step to become law before she left office next year.
The proposal has already outraged libertarians, but the facts are clear: smoking around young children is dangerous for their health and simply not pleasant.
Young people aren't in a position to tell their parents or guardians what to do, but the law can.
