The Examiner revealed on Friday that land on the corner of Cressy Road and Peel Street had been secured for the project.

Ms Knowles said having a regional headquarters at Longford was excellent.

"The small location of the current station is simply not suitable, so we are very, very happy to have one of the main headquarters," she said.

"We hope local people will be contracted to do the build."

Located about three kilometres from the town, Ms Knowles said the chosen site made sense as police would be quite visible.

"It is good for the locals to have a police presence so they can chat about what their issues are," she said.

The $5 million project also has the backing of the Police Association of Tasmania.

Assistant secretary Senior Sergeant Andrew Bennett said they were very supportive and appreciative that the state government continued to recognise the need to invest in developing new infrastructure to support policing.

It has been estimated the project will go out for tender by the end of December or early next year, with HBV Architects working with the government and police to finalise the designs.

The chosen site allows for further development and expansion, with the possibility Ambulance Tasmania and Tasmania Fire Service might also operate from the site one day, creating an emergency services hub at Longford.

Ms Knowles said co-location at the site with other emergency services was common sense.

Tasmania Police Inspector Scott Flude has been heavily involved in the planning process.

"We don't get an opportunity to build a police headquarters every day and this site is perfect for that purpose," he said.

"The community feedback has been really good and there is an option to put other emergency services down there in the future, so I am really happy about it."
