The Government will be making an announcement on improving safety on Auckland's public transport network.

A woman was fatally stabbed on a bus on Wednesday - and 37 year old Aucklander Kael Leona appeared in court today charged with murder.

The ministers of Police and Auckland held talks with AT and Police this afternoon, and Simeon Brown will make an announcement tomorrow.

Police Minister Mark Mitchell told Heather du Plessis-Allan that he has a different role to play.

Mitchell says he's focusing on reassurance at the moment - and will meet the victim's family if asked.

Mitchell says for the past few weeks he and Brown have been discussing with authorities how to improve transport safety.
