But a Christchurch researcher, Dr Murray Laugesen, said: "The annual rise in excise of 10 per cent is not sufficient and Government needs to raise it further to reach that goal. The rate of fall [in legal sales] is insufficient to reach the national goal of less than 5 per cent of adults smoking by 2025."
Tobacco companies say the tax increases will fuel the black market, depriving the Government of tax revenue, as smokers seek cheaper options.
The Ash research, published today in the Australian and New Zealand Journal of Public Health, estimates that of the up to 3479 million cigarettes and loose leaf cigarette-equivalents consumed in New Zealand in 2013, 134.7 million were illegal. This includes about 26 million cigarettes and four tonnes of loose tobacco imported duty free and traded illegally.
"We are not seeing anything that alerts us to a particular problem," a customs spokeswoman said. She said tobacco "detentions" had been rising, but most were not illicit tobacco.
In some cases the importer chose to dispose of the product rather than pay the duty and GST and in others the sums were paid and the tobacco was released.
Contraband tobacco
• 800,000 cigarettes and 221kg of loose tobacco - voluntarily surrendered, plus detected and confiscated by Customs, annual average, 2007-2009.
• 962,000 cigarettes and 2319kg of loose tobacco - annual average, 2010-2013.
Note: Detained tobacco is released if the importer pays all taxes
