The union representing rail workers says its workers feel shaken after a recent fatal shooting in Auckland, and it is calling on their employer to beef up security.
A man has been charged with the murder of Shon Tyson Wanahi, who was shot near the Papakura train station early on Saturday.
The Rail and Maritime Transport Union said Transdev, which runs Auckland's train services, was dragging its heels when it came to improving safety for staff.
Transdev said the shooting happened away from a train or the station, where it said 24 hour CCTV surveillance and Auckland Transport security guards were in operation.
However, it said it will continue working with Auckland Transport, the police and the union on improvements to keep staff and customers safe.
