The Building and Construction Minister is backing scaling back some insulation standards.

The Government's called the changes 'common sense' - with building costs rising more than 40 percent since 2019.

It's expected building code insulation requirements will be relaxed by the year's end.

Chris Penk says they add huge costs.

"Depending on where you are in the country or depending on what the conditions are or which way your house faces, you don't need all of that, you just need some of that. So as long as we can get to the same good overall result without being so prescriptive, then there's money to be saved and houses to be built."
