The caller was in his car talking to emergency services while they looked for him. He told emergency services he is somewhere on a road that leads to Piha Beach.
A Fire Service spokesman said the caller had no data coverage so was unable to use a mobile locate service. The trapped driver was sounding the car's horn continuously and listening for sirens.
The driver had told emergency services there is only 11 per cent battery left on the cellphone.
The Fire Service said the car was now being secured before the driver was winched to safety.
