ASB Bank is sending the message their predicted infrastructure bill isn't an impossible figure.  

The bank's new research suggests a trillion dollars will be needed over 30 years. 

ASB's Senior Economist Mark Smith says it's a huge number and we need to tap into as many funding sources as possible.  

He says there needs to be greater alignment between providers and funders, the infrastructure has to be fit for purpose and deliver value for money, while meeting climate objectives. 

Smith told Mike Hosking that the list is huge and the challenges are massive, but he believes it can be done.
