The Chassis Racers used a circuit on the Cullen Farm in Albany when they started in 1961, this was called "Albany Speedway" and ran Saturday afternoon meetings, but other than the Chassis Racers I don't know if any other speedway divisions raced there. I know a man who raced there, so shall ask the question.
Worrall's Farm was near Kumeu, so a bit away from the areas photographed, will ask around about other venues in the Albany area. I doubt the circuit in Glenfield had anything to do with cars, could be motorbikes, but probably horses.
