An investment banker says the most sensible thing for Kiwibank to do is join the banking oligopoly. 

A Commerce Commission report on banking found the sector isn't competitive enough, as it's being dominated by the big four Australian players.  

The Government's announced its intentions to find investors to deliver Kiwibank up to $500 million dollars to drive competition. 

Financial markets expert Andrew Body told Heather du Plessis-Allan he doesn't think it'll become a disruptor. 

He says that Kiwibank has been around for 23-odd years, and hasn’t been a maverick in that time.
