The introduction of higher insulation standards designed to make homes not only warmer, but more energy efficient, could be delayed even longer. The building code changes were announced last year by the Ministry of Business, Innovation and Employment, with a one year transition period through to November this year. Some in the building industry raised concerns about meeting the deadline, so MBIE sought feedback on a six month extension. A decision is due by July. To discuss the stresses on the industry, Kathryn is joined by David Kelly, CEO of the Master Builders' Association. She'll also talk to Andrew Eagles, CEO of the Green Building Council about why he has concerns about the delay.
