Smokers are a dwindling group in New Zealand with tobacco consumption down 23 per cent in the past five years.
But anti-smoking advocates say rates here are still not falling as fast as in Australia, where the introduction of plain packaging has been credited with a 20 per cent drop in consumption in just three years.
The figures, supplied to the Ministry of Health by New Zealand tobacco manufacturers, show average cigarette consumption has declined 6.3 per cent each year since 2010 equating to a 23 per cent decline in consumption overall.
In Australia figures show consumption has plunged 13 per cent in the last year and 19.6 per cent in the three years since plain packaging laws and tobacco tax increases were introduced.
"Standardised packs and annual tax increases have provided a powerful double-whammy that's saving many lives across the ditch," said Smokefree Coalition Chair Dr Jan Pearson.
