Petrol
prices have risen 48 per cent during the last five years while household incomes increased by 15 per cent, the Green's says.
The party says that's having "a chilling effect" on the economy.
"The more petrol prices rise, the more we have to export just to stay in the same place," co-leader Russel Norman said on Thursday.
"Rising petrol prices are putting enormous pressure on our economy and the key area of oil dependence is our transport sector."
Dr Norman says the government is going to spend $14 billion on new roads during the net 10 years and that's going to make the problem worse.
