This morning, a New Zealand Police spokeswoman said the Serious Crash Unit had finished its investigation at the scene, between Rotongaio Rd and Hinemaiaia Access Rd.
"However, the police investigation will take some time. We will not know what the contributing factors were until that investigation is complete, which usually takes some months."
The highway was partially closed yesterday morning, which caused some delays.
