The driver of a fleeing vehicle involved in a fatal crash near Cambridge remains under police guard while being treated for minor injuries.

Police say the 34-year-old man will be formally charged and will appear in Hamilton District Court later today, once he is discharged from hospital.

Two other people are also in Waikato Hospital, one is in a serious condition and the other is on the critically injured list.

Acting Waikato road policing manager Inspector Marcus Lynam says police are continuing to investigate the incident where a driver who had failed to stop crashed on Scott Street, Cambridge last night.

'We still have a number of enquiries to make but we can confirm that at about 6:30pm, an off duty officer observed the vehicle speeding and driving dangerously.

'The off-duty officer contacted police and a nearby unit located the car driving on Scott Street at about 6.45pm.”

Marcus says the officer activated their lights and sirens but the driver failed to stop and a pursuit was initiated.

A short time later, the vehicle crashed on Scott Street, near Moore Street.

One occupant of the car died at the scene.

'The matter has been referred to the IPCA and the Police Serious Crash Unit is investigating.

'A scene examination was carried out overnight with the road closed until early this morning,” says Marcus.

'Fleeing driver incidents are incredibly tragic for all of those involved, including our staff.

'The officer involved in this incident is being provided with welfare and supported by their colleagues.

'This once again demonstrates the tragic consequences which can happen if a driver chooses not to stop for police.”
