Rt Hon JACINDA ARDERN: The member well knows, of course, that if you're able to legitimately avoid paying a fee by making a different choice, and, for instance, you've got an incentives regime attached, that is not the common definition of a tax. What I would also say is that on that side of the House, based on what I've seen, according to at least Chris Bishop, National was meant to be the party of electric vehicles. If the member is now proposing that they do not wish to have a fee regime attached, then that's $1 billion—$1 billion—over 10 years to fund an incentives regime if it does not have a fee regime attached. I'd like to know how the National Party would pay for that.
