National is criticising the government's transport policies as expensive ideological projects that will inflict additional pain at the pump.
The latest transport policy statement would prioritise $20 billion worth of spending on 14 new roads and public transport links, as well as increase spending on maintenance and resilience projects.
To pay for it, petrol tax would rise four cents each year for the next three years; with funding topped up via general taxation, the Climate Emergency Response Fund, and additional loans.
The total, 10-year plan, is expected to cost $70 billion.
The National Party's transport spokesperson Simeon Brown spoke to Corin Dann.
