A bus caught fire this morning on Auckland's northwestern motorway.

A Fire Service spokesperson said the Fire Service was called to the scene, near St Lukes, at 7.46am.

No one was on the bus, she said.

The Go West bus is on the shoulder on the west bound side of the motorway, just before the St Lukes turnoff.


One fire engine is at the scene and another two are on the way.

Time Saver Traffic producer Natalie Beran witnessed the fire.

"There was a lot of smoke for a while, it's not cleared a little bit. It looks like we've got a least four fire units on scene at the moment," Ms Beran said.
