He saw around 15 police cars, dogs and a helicopter involved in the chase.
Just 200m up the road the guard discovered the chase had come to an abrupt end, with police, some armed, swarming the area.
The eye-witness said the vehicle's tyres appeared to have driven over road spikes at some point during the chase.
A person in a black hoodie, believed to be the driver, is seen walking towards police with hands behind their head before they are brought to their knees.
The person is then made to lie front-down on the wet road while an officer stands astride. Up to three other officers stand guard, making sure the wanted person stays put before they are led to a police car.
The chase completely blocks the normally busy road, with police vehicles boxing in the wanted car, including parking on the footpath.
A police spokesperson said they the drama unfolded after they had found a vehicle of interest about 9.44pm on Wednesday.
The vehicle was wanted after officers had earlier been investigating "serious family harm offences".
"It has been monitored by ground staff towards the South-Western Motorway before the Police Eagle helicopter took over observations from the air," the spokesperson said.
"The vehicle has then been driven at excessive speed along the motorway.
"Spikes were successfully deployed after 10.30pm and it came to a stop in the Pinehill area on the North Shore. Due to the seriousness of the offending staff have conducted an armed traffic stop."
Both occupants were arrested without incident.
A 27-year-old woman has been charged with failing to stop, dangerous driving and drug offences. She is due to appear in the Auckland District Court on 28 July.
A 31-year-old man has been charged with multiple offences relating to an alleged earlier incident.
