National caucus to vote for new leader

The new leader of the National Party will be chosen today, when the 56 MPs will lock themselves into a room and conduct a secret ballot. Simon Bridges has been considered a frontrunner right from the get-go, Amy Adams is also very much in the running. But does she have enough support to secure a win? Whoever is chosen will replace Bill English, who will deliver his valedictory speech on Thursday and then leave Parliament for good. RNZ political editor Jane Patterson joins Susie Ferguson to talk about what's going to happen.
