Three people have been taken to hospital after a crash involving two cars and a truck on an Auckland motorway.
Emergency services responded to the incident under the Alfriston Rd overbridge, shortly after 10am on Thursday.
A St John spokesperson said seven patients were injured in the crash.
Three were admitted to Middlemore Hospital in a moderate condition, four were treated at the scene and had minor injuries.
New Zealand Transport Agency said in a tweet only one lane south was currently open, with congestion quickly building through the Manukau area.
Motorists were asked to either delay or consider an alternative route if possible.
