The return of State Parliament will be delayed by a week in the wake of government member Rene Hidding's resignation amid historical sexual assault allegations made against him which he has strongly denied.
Labor had granted a pair some weeks ago for one government member to take leave but had not received a request from Premier Will Hodgman to grant another pair for the vacant seat - a move that Labor leader Rebecca White labelled on Tuesday "unprecedented".
Mr Hodgman said he had received advice the most appropriate course of action would be to delay the resumption of Parliament which is now set to return on March 19.
He said the Governor had accepted the recommendation and that there would be no reduction in the number of sitting days.
In reaction, Ms White tweeted: "After losing control of his government, Will Hodgman is now running away from governing and scrutiny by delaying the return to Parliament."
This prompted retaliation from Greens leader Cassy O'Connor who said the party could have granted a pair for the vacant seat so the government could not "run and hide".
Tasmanian Electoral Commissioner Andrew Hawkey said a recount for the vacant seat would commence on March 12 which was the day that Parliament was due to resume.
Mr Hawkey said a public notice would appear in state newspapers on March 2 to invite all member who were not elected in the last state election to contest in the recount.
The TEC must allow for a 10-day delay after newspaper advertisements were published for a recount.
Mr Hidding on Monday resigned after the serious allegations were made against him through the media over the weekend.
He denied those allegations and said they were part of an ongoing family dispute with the woman making the allegations.
Mr Hidding said he decided retirement from politics was the best for the well-being of his family.
Two Tasmanian police officers flew to Queensland on Tuesday to take an official statement from Mr Hidding's accuser.
Break O'Day councillor John Tucker confirmed he would nominate for the vacant seat in Lyons.
He finished last on the Liberals ticket in last year's state election with 3404 primary votes.
Mr Hidding is the last House of Assembly member to fall under the Defined Benefits Scheme which was scrapped by the Bacon Labor government in 1999.
A lower house backbencher receives a salary of around $139,000 and a government minister a salary of about $200,000.
Mr Hidding served as a government minister for four years and was opposition leader for four years from 2002.
Under his superannuation scheme, he will receive a lump sum based on a calculation of his time spent in Parliament and loading received for his leadership, ministerial and other duties.
This is believed to be well in excess of $1 million.
He was first elected to State Parliament in 1996.
