Police are cold-calling recidivist drink drivers in an effort to reduce offences on southern roads.
Southern district road policing acting manager Senior Sergeant Steve Larking said officers had been visiting recidivist drivers at home, as part of "targeted enforcement".
"We call it cold-calling, and we go and knock on the door and try and ascertain why they drink and drive.
"We give them the message that police are aware they have a problem with drink-driving and we will be actively looking at them."
The initiative is an extension of "Operation De-Clutch", which began last year in the Bay of Plenty. Results of the push have yet to be revealed.
Figures released under the Official Information Act show there was a small increase in recidivist drink drivers between 2007 (309) and 2011 (321), largely due to an increase in Southland over the same period.
The number of offences remains steady in the southern district, with police recording a 2 per cent decrease between 2007 and 2011.
Mr Larking said those who elected to drink and drive would not "get away with it", as southern police targeted drink drivers via compulsory breath-test sites and regular operations in rural and urban communities.
