A man was caught speeding four times in little over an hour in the Lindis Pass.
Zihao Liu, of Hamilton, was caught by a mobile speed camera three times in 50 minutes travelling between 129km/h and 150km/h on State Highway 8 on September 10.
The 24-year-old's driving prompted the camera's operator to request a road policing patrol.
Senior Constable Phil Beckwith caught the man speeding again about 25 minutes later near Tarras, this time travelling 140km/h.
Alexandra road policing group Sergeant Bruce Martin said police decided to prosecute Liu, who had already accumulated 125 demerit points.
"There was clearly a pattern of poor driving," Martin said, in police magazine Ten One this month.
Liu pleaded guilty and was convicted of driving at a dangerous speed. He was disqualified from driving for six months and fined $750 plus court costs in the Hamilton District Court last month.
