Peter Gutwein said a state-wide skills roundtable, including key industry and business stakeholders, TasTAFE and unions would be held in coming weeks to discuss meeting demand for his "construction blitz" over the next two years.

He said a skills shortage would not be bad news.

"That would be a fantastic problem to have, because it would mean that our construction industry is fully deployed," Mr Gutwein said.

"That's the reason why we're calling together the round table - to ensure that we can provide that skilled workforce.

"That's why I want to have TasTAFE, industry representatives, unions at the table to have a conversation about what we can do to ensure that we are nimble, and that we provide training and support where necessary to ensure that we have those skilled workers."

Construction, Forestry, Maritime, Mining and Energy Union Tasmanian organiser Kevin Harkins warned that he would rather see the blitz slowed if it had to rely on interstate labour.

"It looks good and is about bringing projects forward but I would rather see it slowed if it meant we had to bring in interstate workers," Mr Harkins said.

"We want to create as much for Tasmanians as we can and we want everyone paid properly with no sham contractors.

"If the workforce isn't available you can extend the program, so be it."

Mr Harkins said "quite a few" apprentices had lost their jobs due to the pandemic and should be re-engaged.

"There has been a decline in the number of apprentices employed and those who have been let go in recent months should be re-engaged," he said.

Mr Harkins said he was pleased Mr Gutwein had recognised "the important role of unions" and included them in the skills roundtable.

Unions Tasmania secretary Jessica Munday is also worried about a lack of skilled tradespeople but has welcomed the inclusion of unions in the skills roundtable .

"The government needs to be smart and targeted and make sure local workers are the ones getting the jobs," Ms Munday said.

"How do they plan to do that with a skill shortage? We've already got mainlanders on our current jobs."

Mr Gutwein said apprentices would benefit from more construction projects across the state.

He said under contracts in excess of $250,000, a minimum of 20 per cent of labour would have to be apprentices for work undertaken on government-funded building and construction works.
