Voula Delios, 68, was stabbed 22 times inside her North Hobart grocery store in July 2016.

Daryl Royston Wayne Cook was found not guilty in September 2018 of Ms Delios's murder by reason of insanity. He is now detained indefinitely in a secure mental health unit.

The now 37-year-old is a diagnosed schizophrenic who was in the grip of a psychotic episode at the time of the attack and believed Ms Delios was a heathen whom God wanted him to kill.

The criminal trial heard Cook had been displaying signs of being in the grip of psychotic delusions for months before his release but was not taken seriously because prison staff believed he was "faking".

The trial was also told that there was no follow-up when Cook failed to turn up at an appointment with a community corrections officer before the fatal stabbing.

The inquest into Ms Delios's death was delayed after coroner Simon Cooper was told the State Government had ordered an urgent internal review of prisoner psychiatric assessments and prisoner discharge processes.

Counsel assisting the coroner Jane Ansell said that two of the three "dot points" in the summary of the internal investigations report would now set the parametres for the inquest, which is expected to start in August and run for four days.

The inquest will examine the processes and procedures of prisoner mental health care and assessment, and prisoner releases.

It will also identify options to ensure prisoner mental health care and assessment, and release procedures are appropriate.

Mr Cooper was told none of the civilian witnesses who gave evidence during Cook's criminal trial would be called to give evidence during the inquest and only one detective would be called.

Cook would not be called to give evidence himself.

During the trial, the court was told the Cook had been diagnosed and treated interstate for mental illness — starting in his 20s.

The coroner said a formal application had also been made to his counterpart in South Australia for all of Cook's medical records.

Among those who would be called to give evidence were two prison chaplains who had dealings with Cook and the head of Tasmania's forensic mental health service.

Ms Ansell said she would also be seeking to call someone from community corrections to appear at the inquest.

Counsel for the Prison Service and Health Department, Paul Turner, said the Director of Prisons was already preparing a statement for the inquest.

"It's lengthy and comprehensive," Mr Turner said.

"It's likely to be quite a voluminous document."

The Director of Prisons was part of the investigative taskforce that prepared the report for the Government.

Ms Delios's sister flew in to Hobart from the United Kingdom for a case management conference and Ms Delios's daughter was also in the court.
