But I too want to talk a little bit about the prefabrication provisions because that's the area that I think will have the greatest impact. Rather than go into the sort of the detailed analysis of it, I would like to relay to the House the situation that I well remember when meeting with a business owner who owns and operates a building construction business in my electorate in the Coromandel, in Thames. This is a business that builds holiday homes—baches—and they are largely of the same design. There are, I think, seven or eight designs that this builder builds and, essentially, you can have design No. 1, design No. 2, design No. 3, or design No. 4, and so forth, but that's pretty much it. Really, the only thing that changes in the design of each of those homes is you can maybe, as a purchaser, choose a different coloured paint on the exterior, or different types of taps on the sinks, taps on the bath, or taps in the laundry, but, essentially, the floor layout, the design, the construction, and the plan is exactly the same. So if you buy plan No. 1, you're going to get plan No. 1, and that building will be constructed in a way that is identical to every other one, as I say, with only cosmetic changes.
