Prime Minister John Key has indicated he has little sympathy for Peter Dunne's concerns that information about his emails was accessed without his permission during the inquiry into the leak of a sensitive GCSB report.
Mr Dunne resigned from his portfolios after refusing to release the content of emails between himself and journalist Andrea Vance just before Ms Vance reported on the contents of the so-called Kitteridge report which revealed potentially illegal spying by the GCSB.
It has emerged that former public servant David Henry who conducted the inquiry asked Mr Dunne for the emails after examining "metadata" or logs of Mr Dunne's email traffic.
Mr Dunne said he never gave his permission for this data to be examined.
Mr Key said he had some sympathy for concerns journalists such as Ms Vance may have about their metadata including information about their movements around the parliamentary complex being examined without their permission.
