Southern District police are receiving between 70 and 90 driving complaints a day from the public.
Queenstown Sergeant Keith Newell said along with the reports of bad driving there was also some "good camera footage" from motorists' dash cameras.
He encouraged the public to continue reporting bad driving they encountered.
His call comes as a man arrested for dangerous driving on the Gibbston Highway near Queenstown told police he was rushing to find a toilet because he had eaten too many cherries in Cromwell.
