The Prime Minister says he will bring the Opposition leader on board to hammer out a plan for infrastructure. 

The Government is promoting a message of bipartisanship as it sets its sights on designing a 30-year pipeline for delivering major projects. 

Christopher Luxon and his Transport, Infrastructure, and Housing Ministers visited New South Wales last month to learn from Australia's productivity.  

Newstalk ZB's Kerre Woodham pushed Luxon on why he didn't take Labour leader Chris Hipkins if he's trying to build consensus.  

He says they have already reached out to other parties to make it clear the coalition wants to work in a bipartisan way. 

When it comes to the coalition itself, Luxon insists he's leading a stable coalition, and works well with both partners.  

That's despite the controversial Treaty Principles Bill coming up in this week's Cabinet meeting, and a paper unveiling Act's David Seymour's proposed principles.  

Luxon's adamant he won't support the Bill past first reading and has admitted this was the issue that stalled coalition negotiations.  

Luxon told Kerre the three parties are very different. 

But he says he's very proud of the way he works with both Seymour and Winston Peters.
