Official figures show the police's most active and profitable mobile speed camera van parks up on State Highway 1 through Wellsford.
A mobile speed camera parked between Davies and School roads, a 50km/h zone, has issued 18,294 tickets since January 2018, worth $1.135 million.
The camera location has issued more than double the number of fines than the next most prolific location over that three-year period.
The summer holiday period is the most common time for motorists to be hit with a fine through Wellsford.
