Taskforce Raven members arrested 61 offenders, and charged them with 482 individual offences during their first three months of operation.
The taskforce has cleared 142 offence reports through its work focusing on recidivist offenders and youth crime.
Members have recovered $48,000 worth of stolen property including power tools, jewellery and groceries and seized 8 illegal firearms.
Northern District Commander Marco Ghedini said since the taskforce was established on 3 February this year, the district had observed a downward trend in crime.
"Tasmania remains a safe place to live, and we know that a small number of people are responsible for the majority of crime in Tasmania," he said.
"Taskforce Raven will continue to focus on recidivist offenders, and in just three months, members have delivered strong results, with a significant number of arrests and prosecutions. We have concurrently observed general reduction in crime across the district".
"While the taskforce is just one of a range of strategies, we have certainly seen positive indications since its inception."
Taskforce Raven will continue indefinitely, working in conjunction with Northern CIB, Launceston Uniform and the Northern Drugs and Firearms Unit.
"Through a combination of high visibility foot patrols and proactive investigations, members of the community can expect to continue to see taskforce members out on the streets," Commander Ghedini said.
"We know concerns about youth crime, and anti-social and unlawful behaviour, particularly within the CBD remain. I can re-assure the communities of Northern Tasmania that our strong focus will continue and ask for your ongoing support.
"We continue to encourage anyone with information that may assist Taskforce Raven to contact police."
