A police spokeswoman said officers were alerted to the incident, at Taka St in Takanini, about 7.45am.

GOOGLE MAPS Taka St had been closed between Great South Rd and Takanini School Rd.

Paramedics and firefighters were also attending.

The spokeswoman said the driver had "moderate to minor" injuries.

Auckland Transport warned commuters to expect "disruptions and cancellations" to southern line rail services.

The line was suspended between Papakura and Homai for 90 minutes. Trains from Britomart were being turned around at Homai.

Commuters were also delayed on the eastern and Onehunga lines, and the western line was experiencing some "minor delays", Auckland Transport said.

Taka St was closed between Great South Rd and Takanini School Rd for about an hour following the incident, and Takanini Rd was also closed.

The streets were re-opened just before 9am.

Police at the scene say the train received minor damage, as did the ute, which was only clipped rather than hit head on.

Passengers on the train had disembarked and were being transported to their destination by buses.

The southern line was re-opened about 9.15am, and passengers were asked to expect delays as services returned to normal.
