Hon GRANT ROBERTSON: We're going to come to that matter in a moment, but I would say that the member will be well aware that fuel taxes, as they are paid for through the fuel excise duty and the road-user charges, are hypothecated to transport. That is an engine of growth in the economy. And I do note that, in the wake of the global financial crisis, when the previous Government was in power, on 1 October 2009 they increased fuel excise duty by 7 percent.
