Peter Gutwein was today condemned for his blatant negativity which has now seen him stoop to playing politics with the jobs of Nyrstar workers.

The Premier, Lara Giddings, said Mr Gutwein's baseless fear mongering about the closure of the Hobart zinc smelter represented a new low in the Liberal Party's campaign of relentless negativity.

"Mr Gutwein openly admitted he had no evidence that Nyrstar's Hobart smelter was under threat from carbon pricing, in fact he was told the opposite by management, and yet he made the claim anyway," Ms Giddings said.

"This is a disgraceful example of a party that is prepared to use workers as pawns in their cynical political game.

"Mr Gutwein has long been a master of negative politics but now he has stooped to a new low of just making things up.

"It makes a mockery of the Liberals' claim that they have a positive agenda for Tasmania when they invest all their energy in pedalling fear and negativity in the community.

"This is the party that whipped up fear about the closure of Pacific Aluminium and TEMCO at Bell Bay and made barely a whimper when it was confirmed that the jobs of nearly 1000 Tasmanians were safe.

"The Liberal Party are trying to destroy confidence and spread lies because they think it will help them win power."

Ms Giddings said in contrast the State Government had a positive forward-looking agenda for Tasmania.

"We have helped to secure the future of major manufacturers in Tasmania while also investing in new initiatives to double the size of the dairy industry, double aquaculture and quadruple the wine industry.

"The Liberals constantly cherry-pick data to suit their political ends while ignoring positives in the economy, including the announcement of job-creating projects like the $70 million Proto Resources mine at Beaconsfield and the massive $758 million pipeline of investment in the construction industry."

Major projects either underway or soon to begin include:

- The $400 million Musselroe wind farm;

- The Institute of Marine and Antarctic Studies;

- Dairy investment including a new milk processing plant at Smithton, the $140 million redevelopment of National Foods' cheese factory in Burnie and a major dairy expansion planned by the Van Diemen's Land Company;

- The Menzies Research Institute;

- The Myer Redevelopment;

- The $35 million renovation of the Tasmanian Museum and Art Gallery;

- The transformation of Macquarie Wharf 2 into an Antarctic research and cruise ship terminal;

- $50 million to remediate the Macquarie Point rail yards to prepare the massive site for commercial development;

- The accompanying construction of a new Brooke St Pier ferry terminal;

- Confirmation that Bunnings plans to build a second store in Launceston.

"That is hardly evidence of a stagnating economy, as Mr Gutwein claims."
