Underage teens are drinking less than their counterparts were 10 years ago, but adults are not.
Binge drinking has decreased among 15-17 year olds over the last two years, with 3.2 per cent of teens in this age group consuming six or more units in one session every week.
In 2006/2007, 8.4 per cent of 15-17 year olds were in this category.
However, hazardous drinking across all age groups has increased over the last 10 years, according to the Ministry of Health.
Kevin Sinnott, spokesman for the Brewers Association, said there is anecdotal evidence of a change among young people.
