Nearly 20 years ago, the Government made it illegal to sell single cigarettes.
That law change meant that cigarettes could only be sold in packets of 20 - and for good reason. It's to make them too expensive for kids to buy.
But some dairy owners are openly flouting the law selling cigarettes one at a time.
The illicit sales have outraged a group of young Māori women who are campaigning to stop the practice.
They've taken the first big step by exposing the trade. Native Affairs followed them as they went undercover to expose this illegal practice.
