The Government's making changes aimed at bringing down the cost of building homes.  

It's introduced new legislation to make it easier to import building supplies from abroad.  

It'll enable recognition of overseas standards and Building Consent Authorities will need to accept products already certified offshore.  

Building Industry Federation Chief Executive Julian Leys told Ryan Bridge this will impact a number of supplies. 

He says they're looking at products with the biggest costs - like internal linings, external claddings, windows, plumbing products and insulation.  

The Bill will have its first reading later this month.
