Last week the ninth-known prisoner in four years was released from Risdon incorrectly but was returned to jail on Saturday without incident.

Society president Evan Hughes said several measures had been implemented over the years to address the problem.

"The best answer to this is the implementation of the Justice Connect program," he said.

The state government is investing $24.5 million over four years into the ICT program, which will centralise systems between the Justice Department, courts, police and corrective services.

"It is a necessary step forward and I'm very pleased the government has acknowledged that. It is certainly supported by the legal community," Mr Hughes said.

In November, The Examiner revealed prisoner Josh Brown had been incorrectly released 28 days early.

He was left in limbo after spending two weeks adjusting to life back in the community.

Brown was returned to custody two days before his actual release date.

Mr Hughes said prisoners were generally understanding of the situation and lawyers played an important role in correcting the mistake.

"It creates difficulties for prisoners, it unsettles the community and it is complicated for lawyers because they haven't escaped but they're technically still serving a sentence," he said.

Mr Hughes said the society had an excellent relationship with the prison and regularly met with the director to work through prisoner contact and accessing sentencing information.

The state government is working to implement a Sentence Management Division before July to prevent further bugled releases.

The division will be responsible for calculating sentences, ensuring accurate record-keeping, interpreting warrants and imprisonment orders, liaising with the Tasmania Prison Service and the courts, and authorising releases.
