Launceston's northern suburbs were locked down on Wednesday as part of an ongoing police operation targeting prolific offenders.
About 20 Tasmania Police officers were involved in the operation which saw 450 random road breath tests conducted at stations set up on George Town Road and connecting side streets at Mayfield.
The planned action was an initiative of Operation Raptor, a taskforce created in response to increasing crime rates in Launceston.
Acting Sergeant Aziz Melick said the taskforce had targeted recidivist offenders who continued to break the law, despite their dealings with police.
"We weren't necessarily expecting to have such results today but it has been positive and hopefully we've made a dent in the crime rate in Launceston today," acting Sergeant Melick said.
Police executed warrants, searched vehicles and conducted random breath tests from 1pm to 2pm, with the helicopter used in case people tried to evade police or flee from the houses being searched.
Of the 450 random breath tests conducted, police caught six drug-drivers, two disqualified drivers and one drink-driver.
A number of people with outstanding arrest warrants were also intercepted during the blitz, with one person found in possession of knuckle dusters.
Acting Sergeant Melick said the taskforce was particularly focused on volume crime including home burglary, car burglary and shop stealing.
According to crime statistics released in March, business burglaries are up 33 per cent in Launceston compared to the same time last year.
"Our most prolific recidivists offend constantly and our taskforce officers are monitoring them very closely to hold them to account," he said.
The data also revealed motor vehicle burglary offences, which include tampering with cars, has increased by more than 79 per cent in the area compared to March 2018.
Acting Sergeant Melick said the results of Wednesday's operation at Mayfield were quite telling.
"I spoke with a number of members in the suburb today who are pleased to see a police presence.
"They're fed up with these minority offenders who are continually disobeying the road rules."
Acting Sergeant Melick said people could help prevent their homes, cars and businesses from being targeted by take away the easy opportunities for these people to steal.
The north's favourite labrador was also out in force at Mayfield, with police dog Fang used to sniff out illicit drugs on motorists.
"We've seen really good success with police dog Fang," Acting Sergeant Melick said.
Police remained tight-lipped on future operations, but said it won't be the last Launceston sees of the taskforce.
