At times he crouches down on the board to take the lefthand bends, and puts his hand on the road to steady himself. The ride comes to an end at the base of the hill in the driveway to Atlas Quarries.
After watching the video, Northland road policing boss Inspector Wayne Ewers said there was no specific offence for the actions of the skateboarder, but a person engaging in such activities could possibly be charged with endangering transport.
Police records showed there were no *555 reports made around the time the video was posted online.
"It is difficult to estimate his speed as well but sufficient to say if he had fallen off into the face of an oncoming vehicle it would have clearly added to the statistics. I can say it's an act of stupidity." Mr Ewers said.
"The Brynderwyns require good concentration levels when driving over them and they have seen a number of serious and fatal accidents in recent years. Behaviour of this type not only endangers the skateboard rider but puts other road users at risk of being seriously injured or killed."
The Northern Advocate tried to speak with Matt Boortman but he had not replied by edition time.
Northland's road toll stands at five so far.
