The evidence is very clear internationally that the overall effect of these schemes is a progressive effect, that it gives the biggest advantage to the lowest income people and there's strong evidence, particularly out of the Californian schemes, to support this, and that's because there's a massive lifetime saving for people who get cleaner vehicles in terms of the ongoing fuel costs. It's something that people are feeling at the moment. To fill up an electric vehicle, if you have one, is the equivalent of filling up at the rate of 20c to 40c per litre. The more of those vehicles we can get into the fleet now, the more we'll start cycling through the fleet and becoming more affordable. Already under the modelling for this scheme, we know that there are large vehicles, including hybrid vans, that either do not attract any charge or attract a discount under the scheme that's here. And, again, the point of this is to incentivise the importers to bring in the cleaner models that are not currently available to purchasers in New Zealand because there is no incentive for that. That will advantage middle and low income earners, who will save money by getting more efficient vehicles to use.
