One person has died after being hit by a train at Ranui, West Auckland.
Emergency services were called to the incident at 6.55 this morning and are currently at the scene.
Police said Metcalfe Rd is closed between Pooks Rd and Ranui Station Rd, and diversions are in place.
Auckland Transport tweeted that Western Line train services will stop at Henderson because of an emergency at Ranui.
NZTA has advised that trains on the Swanson line will be affected after a "serious incident", and Metcalfe Rd is closed near the level crossing.
The crash comes as the New Zealand rail industry marks Rail R U OK? Day today, with a focus on creating a more supportive environment for rail workers exposed to trauma on the job.
The initiative was founded by TrackSAFE Foundation, and chairman Bob Herbert said depression, anxiety and mental trauma are "very real issues impacting rail staff and first responders, and regular meaningful conversations can really help".
'He has disregarded our voice and continued with this divisive kaupapa.'
