Two people are dead and two injured - one critically - after a horror smash in West Auckland overnight.
Police confirmed the deaths this morning, saying the crash happened after a patrol car saw the vehicle travelling "at speed" on Henderson Valley Rd.
Officers turned around to investigate.
Detective Inspector Kevin McNaughton, of the Waitematā CIB, said: "The vehicle has continued along Henderson Valley Rd at speed, some distance from our officers.
"The officers did not activate lights and sirens."
Police, fire crews and ambulance were called to the collision on Henderson Valley Rd just after 12.30am.
The vehicle slammed into a power pole, scattering debris across the road.
McNaughton said officers found the crashed vehicle, which appeared to have had its lights turned off.
"The officers have immediately attempted to provide first aid to the occupants. Tragically, two people have died."
Police confirmed two other people are in hospital - one in a stable condition and the other critical.
The next of kin have been told, police said.
A witness said it appeared that the vehicle had struck a power pole.
Firefighters could be seen working near the car, which had been severely damaged in the smash.
Auckland Transport alerted the crash at 6.15am today, telling locals that part of Henderson Valley Rd, near the intersection of Woodruffe Ave, is closed until further notice.
Powerlines are affected and it is understood that contractors are on site fixing them.
"Avoid this route or allow extra time for diversions on your essential journey," road authorities said.
Police are now investigating the crash and a scene examination has been carried out. The Serious Crash Unit is also there.
The Independent Police Conduct Authority has also been notified, police said.
