Now, before I go any further, I didn't say this beforehand, but I do want to thank the committee for the work that they have done on this and I want to thank the officials who've worked on not only this part of the building reform but other pieces of work to ensure that at the end of the day, we build safely; we build buildings that we can futureproof, buildings that actually don't cost us a lot to heat, buildings that, in terms of their maintenance and energy costs, help us to meet our obligations, and at the end of the day help us to build more homes for Kiwis.
