As part of an anti-smoking crackdown, the government is also banning smoking in public spaces, along with the sale of five-pack cartons.
It says the sale of so-called ‘loose smokes’ will be stopped.
Hundreds of thousands of people who make their living by selling individual cigarettes on the street could be affected by the new enforcement.
But Health Minister Jamie Maxtone-Graham is remaining firm on the issue.
“Selling loose cigarette is the worst thing you can do,” he told Radio Australia’s Pacific Beat program.
“In my opinion as the minister for health, this is a no-no and this will be stopped. I’m not backing down on this.”
Medical workers in Papua New Guinea have welcomed the government’s firm stance.
Ellie Winge, from Port Moresby General Hospital, says the situation will only get worse as the country’s population grows.
“What will happen to us in 20 years time, in 15 years time?” she said.
“[The] health department and minister for health, they have to do something that has to be some sort of control in the country.”
