Anti-smoking campaigners are celebrating the introduction of plain cigarette packaging saying it will make smoking less attractive to young people. 

From Wednesday, tobacco products will be sold in non-branded packets, but will still display the usual health warnings. 

Campaigners warn there's still a long way to go to make New Zealand smokefree by 2025. 

Boyd Broughton from Action on Smoking and Health (ASH) says the government needs to set their goals. 

"The government needs to have a plan. And then you have a plan with some goals and timelines, and they need to be held accountable. So we need to get that plan which they promised in 2014." 

Retailers have until June 6 to sell the last of the old designs.
