There’s a belief a cap on public transport fares would be better bang for buck compared to other roading projects.  

Labour's campaigning on a $20 weekly maximum in Auckland, Wellington, and Christchurch, and $10 elsewhere. 

It would be funded by re-prioritising $65 million from the National Land Transport Fund. 

Independent urban planning expert Bruce Weir told Francesca Rudkin for some projects, $65 million doesn't go very far. 

He says when it's sunk into the roading network, it's chewed through pretty quickly and doesn't bring many long-term benefits. 

But the benefits of the policy, like increased use of trains and busses, could be slow to filter through. 

Weir thinks it'll take about three-to-five years to see any direct impacts.
