Tasmanian Labor will unveil the details of its planned budget savings amid a warning from credit rating agency Moody's.
Premier Lara Giddings says planned savings measures, if her party is returned at the March 15 election, will be announced at the weekend.
The major party's responses to a $450 million budget blowout over the forward estimates have become a major election issue.
Liberal leader Will Hodgman has pledged $500 million in savings, including the axing of 500 public service positions.
Ms Giddings has campaigned on prudent financial management and says her spending promises amount to $105 million compared with the opposition's $378 million.
She accuses the Liberals of a Campbell Newman-style plan to sack up to 1200 people.
The premier, who has been under pressure to say how she will address the budget problem, says details of her plan will be released on Saturday.
"What we won't be doing is cutting jobs," she said.
Labor's savings will be released a day after Moody's affirmed Tasmania's AA1 rating, but revised its outlook from stable to negative.
The agency said it expected the state's deficits to increase with slow economic growth and lower revenue from federal sources, including windfalls for Hydro Tasmania when the carbon tax is axed.
Moody's cut Tasmania's credit rating from AAA in 2012.
Shadow treasurer Peter Gutwein slammed the budget management of the government, which recently abandoned a planned return to surplus by 2017.
"This is an indictment on the economic management of the state by Lara Giddings and Labor and puts the lie to Ms Giddings' claim that the state has turned an economic corner," he said.
"If an election were to be held tomorrow, the budget would be better off by around $110 million under the Liberals."
Ms Giddings said her government had reduced annual spending growth of nine per cent to less than two.
The campaign continued on Friday with opposition leader Will Hodgman taking on a local radio host in a three-round boxing bout to highlight his party's support for police youth services.
"It was an experience I didn't enjoy," Mr Hodgman said.
Three parties will officially launch their campaigns on the weekend - the Liberals on Saturday in Launceston, Labor and the Palmer United Party in Hobart on Sunday.
