Prime Minister Christopher Luxon joined Mike Hosking in studio to discuss two major policy changes announced last week - abolishing fees free study, and raising the age of superannuation. 

Luxon said that although the changes may not be 'politically popular' they are important, and other party's aren't brave enough to agree. 

"I think they're being quite dishonest in terms of not facing up to the challenge that we've got and I think just chucking it down the road to the kids and grandkids isn't the right way," he said. 

"So, I get it's not politically popular, but actually we should have a bigger conversation and a debate about it."
