Shane Jones says "structural change" to the energy sector is definitely on the agenda following the closure of two central North Island mills.
Winstone Pulp has confirmed it’s closing its two mills near Ohakune, with 230 people set to lose their jobs.
Jones says the Government can't control factors like global commodity prices, foreign exchange rates, and global shipping logistics.
But the Regional Development and Associate Energy Minister told Mike Hosking the power of large "gentailers" needs to be broken up to make energy prices more competitive.
He says the aluminium sector is looking towards importing, there's uncertainty for corn growers, and the country's biggest gas user Methanex has been facing issues.
