Motorists are being warned to expect delays on the Southern Motorway southbound at Takanini following a crash.
Police were called to the scene between Hill and Alfriston Roads at 7:14am after a vehicle crashed into the barrier and rolled.
One person has moderate injuries and another has minor injuries.
The motorway is currently down to one lane so traffic is building.
Police ask that motorists are patient if they experience delays.
