Legislation setting up a legal framework for collective bargaining across industries is set to become law.
The Fair Pay Agreements Bill has passed its third reading in Parliament, with the support of Labour, the Greens and Te Pāti Māori.
The bill provides a framework for collective bargaining across occupations - like cleaners, supermarket workers and security guards - rather than just between unions and employers.
National and Act oppose the measures, which they say will hurt small businesses, and vow to repeal the law if elected next year.
Business NZ chief executive Kirk Hope and New Zealand Council of Trade Unions president Richard Wagstaff spoke to Corin Dann.
