One of the two police officers who was shot during a routine traffic stop in West Auckland this morning has died.

There are reports two people were arrested after the Armed Offenders Squad surrounded a house in Massey this afternoon, following the shooting.

Police Minister Stuart Nash says the police officer who died in the shooting was a man who had dedicated his career "to keeping us safe."

Police Commissioner Andrew Coster confirmed at a media conference this afternoon the officer had died and said it was "absolutely devastating" news.
