About 70,000 fewer adults smoke tobacco daily now than three years ago, the latest official survey has found.
The Health Ministry will today release smoking prevalence data, including the ethnic breakdown of the figures, from its latest New Zealand Health Survey, conducted last year and this year.
However, a preview snippet of the results, already published on the ministry's website, says the provisional data indicates that about 17 per cent of people aged 15 or older are daily smokers. That equates to about 600,000 people.
The prevalence was more than one-tenth lower than in 2009, when the ministry found that 19 per cent of adults smoked daily.
