The fuel excise duty, which is hypothecated on being applied to roads through the New Zealand Transport Agency, has been collected from recreational and commercial aircraft operators who use a clean, green fuel—what they call motor gas, which is far cleaner and far greener than the old aviation gas, which contains lead. Those businesses and those recreational pilots which have chosen to upgrade their aircraft or upgrade their engines to motor fuel are now captured by this fuel excise duty, and they've been asking for an exemption. In fact, they asked the previous Minister for an exemption, and the previous Minister's office, and they didn't receive an adequate reply. So they continue to raise this with the ACT Party, because they know that the ACT Party is the association of consumers and taxpayers.
