A reshuffle in the NT has seen a former anti-fracking unionist take over the resources portfolio.

Chief Minister Michael Gunner has announced the second ministry reshuffle in his Labor Government's term.

Mr Gunner gave himself the Business and Innovation and Defence portfolios – adding them to a list that already includes Northern Australia, Trade and Major Projects, Treaty and Children.

He said the new roles would allow him to cut red tape and bring work to Territory businesses.

“The business community has said loud and clear that they want to see the cutting of red tape,” Mr Gunner said.

“The Government has listened and I am taking personal responsibility for reducing red tape for Territory businesses.

“I also want as much of the $20 billion defence infrastructure investment to be delivered by local Territory businesses, which is why I have taken on the Defence Jobs portfolio.”

Paul Kirby has been given that Resources and Primary Industry portfolios, after “years of experience working with the oil and gas industry”, the Government said in a statement.

That experience came while Mr Kirby was a representative for the Electrical Trades Union, which was fiercely opposed to fracking.

But he says he “absolutely” support the Government’s pro-fracking stance.

Selena Uibo takes on Aboriginal Affairs, in addition to her Education and Training portfolios.

Dale Wakefield has added the new Energy Policy portfolio to her renewables portfolio.

Deputy Chief Minister Nicole Manison is now the Multicultural Affairs minister, adding to her existing portfolios of Treasury and Police, Fire and Emergency services.

Environment Minister Eva Lawler has added Climate Change to her portfolios.

The NT Government says the portfolio name changes will not require additional expenditure.
