What this legislation does is to facilitate that in two ways. The first is through the clean car standard. The standard is about making sure that we actually have a vehicle emissions standard, like nearly every other country, for new vehicles coming into New Zealand. It sets targets which get more ambitious year by year, and it enables importers with considerable flexibility to meet those targets by banking, borrowing, and being able to trade their credits if they are not able to achieve. These schemes have been shown internationally to make a big difference. The most important thing they do—and importers already tell me this—is they enable New Zealand importers to go to their head offices and actually get the stock of clean vehicles here, because there is now a regulatory direction, like every other country. Previously that was not in place, whereas other countries did have it, and so importers found it hard to get the stock of clean vehicles here that Kiwis want. So it's already making a difference in that respect. The clean car discount then accompanies it and helps to stimulate demand by incentivising Kiwi consumers to swap the dirtier vehicles for the cleaner vehicles. As I say, that has already been shown to be working, and it works in country after country after country internationally.
