We need to reduce waste. Housing and construction contributes 40 to 50 percent of the waste that goes to landfill each year. Again, we heard from submitters that because demolition is a permitted activity in areas like Auckland, there is no control or encouragement for construction waste to be reduced, for sorting to occur on site, for materials to be recovered. Things like Homestar standards do improve that commitment to sustainability. The Labour members have said that things like improvements to the building code belong in the Building Act. Yes, they do. But where there are provisions which prevent councils from using their plans to put in place higher standards than apply in the building code and when there is no regular periodic review of the building code to catch up with what is being done in housing developments overseas, we think we need to use the opportunities that bills like this provide to have more warmer, more pleasant, and more energy-efficient homes. So it was disappointing that that did not happen.
