Emergency services are at the scene of a two-car crash on Auckland's Southern Motorway.
The New Zealand Transport Agency has asked motorists travelling southbound to take care through Tip Top corner.
The crash is not blocking any lanes however care is needed, they said.
Three people have been injured in the two-car crash at Mt Wellington, a St John Ambulance spokeswoman said.
One person had moderate injuries, and two were in a minor condition, she said.
Paramedics were called to the scene shortly after 11am.
A Fire Service spokesman said firefighters went to the scene, but no one was trapped, so crews had been stood down.
