Four people are dead and a child is seriously injured following a fatal crash on State Highway One, Waipu this afternoon.

The crash, involving a logging truck and a car, occurred just after 1pm.

Initial indications are that the car was making a u-turn when it hit the oncoming truck. Police are still at the scene investigating the crash and are in the process of identifying the deceased.

The road will be closed for several hours.

The diversion is Rosythe Road onto Mountfield Road for traffic heading north and Mountfield onto Rosythe Road for traffic heading south.

The diversion is suitable for all traffic.

Northland Road Policing Manager Inspector Murray Hodson says this is a very tragic incident, which appears to be caused by a momentary error of judgement.

'Our hearts go out to the families of the victims especially at this time of year when families are getting together to celebrate Christmas.”

The crash is a reminder for all drivers to stay focused and concentrate on their driving. 'One mistake can lead to fatal consequences.”

Mr Hodson says there are already reports of drivers speeding to get to their destinations after being delayed by the crash.

'Please slow down.

"We want you to get to your destination safely and police do not want to attend another crash like this one.

"We also don't want to tell other families that their loved ones have died on the road this Christmas.”
