The Northern Infrastructure Forum says key highway projects will deliver game-changing perks. 

Its data shows the proposed Warkworth to Wellsford and Cambridge to Piarere routes would each add up to $500 million annually to our GDP once operational. 

That's $6 billion over 20 years. 

It would be generated through improved supply chain efficiency, resilience, and business productivity. 

Forum Chair, Simon Bridges, told Mike Hosking that the strongest message is that we should get on with these. 

He said that ignoring them is leaving money on the table.
