Police warn motorists of 'notorious' stretch of road

Police are advising drivers to take "extreme care" on a dangerous stretch of road in Northland after a major crash left three people dead.

Police say a vehicle crossed the centre-line and collided head-on with north-bound traffic in the Oakleigh area on State Highway 1, south of Whangarei.

They are working to identify the victims - two women and one man.

Two others were injured in the crash, with one man in a serious condition and a woman with moderate injuries.

The stretch of highway is known for its high crash rate.

"This piece of road is notorious and people have to take extreme care on it," says Inspector Wayne Ewers.

"Take care on any road when you're driving and make sure you're aware of the road rules, and what can and can't happen. Just take extreme care."

This was Wednesday's second fatal crash. A person died in Dunedin, when their car hit a power pole in the morning.

The road toll for 2017 has now reached 317, compared to 264 this time last year.
