Driving drunk is no longer being tolerated by Northland communities and the "mood swing" is helping to bring down local conviction rates, a road safety advocate says.
The comments follow new figures showing the number of Northland drink-driving convictions is down, but the number of recidivist offenders rose last year.
Ministry of Justice figures released under the Official Information Act show more than 1200 drink drivers were convicted in the year to June, compared to more than 1700 two years earlier. More than a quarter recorded their third or subsequent conviction last year - a small rise in recidivist offender numbers from 2011/12, but a significant drop from 2010/11.
A man in his early 20s was convicted in Whangarei last year for the region's highest breath alcohol reading of 1445 micrograms of alcohol per litre of breath, more than three times the legal limit.
The previous year, a woman in her 40s claimed the dubious title with a reading of 1433mcg.
