A joint political inquiry into manufacturing is to be led by the past president of the Manufacturers and Exporters Association.
The Labour, Green, New Zealand First and Mana parties are holding the inquiry.
The Opposition parties say 40,000 jobs have been cut from the manufacturing sector in the past four years and change is needed to reverse the trend.
Cameron Moore, a long-time director and chair of large manufacturing firms here and in Australia, has been appointed to lead the inquiry.
He says he welcomes the parties' commitment to developing better policies, and the decline in manufacturing needs to be taken seriously.
The inquiry will begin public hearings next month.
