In 2013 Sir John Key announced a second harbour crossing at an Auckland Chamber of Commerce meeting when he was outlining the then-National Government's transport policy.

A decade later Prime Minister Chris Hipkins and Transport Minister David Parker announced the proposal for a second Waitematā crossing: two three lane tunnels and a light rail linking Albany to the CBD.

Sir John Key joined Kerre Woodham to discuss the proposal.
