A person is seriously injured and another has moderate injuries following a two-car crash on Auckland's Southern Motorway late on Saturday night.
The motorway only reopened this morning at 5.30am after emergency services had to extract a person in a third vehicle that crashed into the two cars shortly after.
Police were called to the incident at East Tamaki around 11.50pm last night.
"The driver of one of the vehicles decamped on foot," a police spokeswoman said.
