Time is almost up for anyone wanting to make a submission on whether New Zealand should legalise the sale of e-cigarettes.
The Ministry of Health proposal would restrict purchases to those over the age of 18, and ban their use in smoke-free areas.
Submissions close at 5pm on Monday afternoon.
Many smokers have credited e-cigarettes with helping them to quit the habit.
It's received the backing of ACT leader David Seymour and Maori Party co-leader Marama Fox.
"There's no downside for legalising e-cigarettes," Mr Seymour said earlier this year.
"The reality is it's the tar that kills you from smoking, and if I had a choice from being addicted to tar or to vapour, I'd choose vapour every time."
