A resident who did not want to be named said the drama unfolded about 7.30am when the driver went onto the beach on Auckland's North Shore.
She claims the driver told a passerby he was trying to turn around, however the woman said there was plenty of room above the beach on hard ground to manoeuvre.
"They needed to drive down a 50 metre pavement to get onto the beach. They are a law unto themselves and often drive like this," the resident said.
"The Armourguard driver seemed to think it was quite a joke - took them at least two hours to work out they needed to call a tow truck to get them out, just in time."
In that period the tide had begun to lap at the rear of the car.
