A handful of Nelson residents are continuing to flout the the law, by driving so drunk they wouldn't even pass a test with the old limits.

Police stopped 10 drink drivers during a road policing operation in the region last week.

Senior Sergeant Grant Andrews says one driver was caught almost four times over the new legal limit - while on their way to pick a child up from school.

Grant Andrews says with Easter coming up - police are planning to bump up their presence on the region's roads.
