UPDATED 9.58AM The Maori Party wants pilots and research done in New Zealand on vaping.
It wants taxpayers to subsidise the cigarette alternative in a bid to stamp out smoking.
Co-leader Marama Fox said there have been a lot of studies on vaping but most haven't been done in New Zealand and many have been inconclusive.
However, she told Mike Hosking there's been one five-year piece of research on it.
"That's produced very positive results around illnesses or lack of, and also the moving of people off the cigarettes," she said.
Fox said some statistics shows vaping is harm-reducing, not cancer-causing and that it's a good cessation tool that moves people off cigarettes.
She said people who are vaping will tell you it's been better on the pocket, they're having greater success and are feeling better in their life.
"And so it is a bit of a movement, but you're right, there is a lot of variable data, and we want to move carefully along this line."
