Crash on Auckland’s Northwestern Motorway leaves one person seriously injured

One person is in serious condition after a crash involving two vehicles on Auckland’s Northwestern Motorway.

A Hato Hone St John spokesperson said two ambulances were called to the scene just before 6pm.

“Five patients were assessed and one has been taken to Auckland City Hospital in a serious condition.”

NZ Transport Agency Waka Kotahi said the crash initially reduced SH16 to two eastbound lanes next to Newton Rd, approaching Spaghetti Junction.

However, the vehicles have been moved to the side of the road and all lanes have now been reopened.

FINAL UPDATE 6:35PM
