A motorist who was snapped driving at 170km/h on a north Waikato road then blew over twice the legal alcohol limit when he was pulled over, police allege.
Waikato police say they are horrified by the driver's antics north of Huntly on Saturday night.
The district's road policing manager, Inspector Freda Grace, said a highway patrol unit on a routine patrol on State Highway 1 noticed the south-bound ute approaching him at speed about 7.30pm.
"The officer saw the vehicle coming towards him by the Ohinewai-Tahuna overbridge and thought it looked like it was travelling pretty fast but it wasn't until he activated his radar that he realised just how fast it was actually going," said Mrs Grace.
"The front-facing radar locked on to the vehicle at 170km/h and the rear-facing device confirmed the same speed, if the officer was alarmed enough by the speed the driver was travelling at he was due for another surprise."
