Today further allegations against Michael Wood over comments he made to a journalist about his Auckland Airport shares.

It's also emerged his shareholding was raised three times with Jacinda Ardern's office - and it was wrongly told Michael Wood had sold them.

A formal probe into his reporting of his financial interests has been launched.

His colleague Jan Tinetti was under pressure too - grilled by Parliament's Privileges Committee over whether or not she deliberately misled the House.

RNZ political reporter Katie Scotcher has the story, and RNZ political editor Jane Patterson joins Lisa Owen with the analysis.
