In Focus on politics, Katie Scotcher explores the challenges and priorities in the inherently political transport sector.

The government is at a transport crunch point - Labour's first year as a majority has seen it scrap or reshape major projects and programmes, while decisions about the future of others loom.

The usual challenges of the inherently political sector are being compounded by the financial pressures from the pandemic and the urgent need to respond to climate change.

"It's a minority of cars and trucks on the road that actually have to be in cars and trucks and if we've got plenty of roads, if we use them better, the best way to use them better is to invest in the alternatives that make it viable for the ordinary short trips people are making to school, to work, to the shops to either be by active or public transport."

Changes in transport will be key as the government works to make New Zealand carbon neutral by 2050.

Transport is the second-largest source of emissions, after agriculture. The Climate Change Commission has said the scale of the changes needed in the sector cannot be overstated.

Michael Wood said those changes are his number one priority…
