A motorcycle passenger who suffered critical injuries after landing on his face is the latest in a string of avoidable crashes in the Waikato that are frustrating road police.
The latest was an example of people doing virtually everything wrong, Waikato road policing manager Inspector Freda Grace said.
A young man now faces a long recovery period from potentially life-changing injuries.
Emergency services were called to the scene of a crash on Huntly's Rosser St on Tuesday night after the driver of a mini dirt-bike crashed about 7.20pm.
Grace said initial indications were that the 18-year-old rider of the unregistered motorcycle and his 21-year-old passenger were travelling south towards Connolly Pl and were trying to overtake another vehicle when they hit a pothole. The rider lost control, mounted the kerb and crashed into a fence, Grace said.
"The passenger came off the bike and landed between the fence and a concrete retaining wall, suffering critical facial injuries while the rider suffered moderate gravel rash injuries."
Both were taken to Waikato Hospital and the passenger's injuries were believed to be survivable.
The serious crash unit is investigating and police are awaiting the results of blood tests to establish what, if any part, alcohol played in the crash.
"Irrespective of that, given the rider had no licence and the motorcycle was unregistered - the pair should not have been on the road in the first place."
Grace said police were wondering when motorcyclists would take ownership of the problem as the crash follows two serious injury motorcycle crashes in the Coromandel on Saturday.
The first happened about 1pm and involved two bikes colliding head-on on a speed restricted corner on State Highway 25 about 2 kilometres west of Whiritoa. One of the bikes was unregistered
Both riders were taken to Thames Hospital with minor to serious injuries.
"When emergency services finished clearing the scene there, another rider was reported to have been injured in a collision between his motorcycle and a tree on SH25A near the summit of the Kopu-Hikuai Rd.
"We're taking too many risks.
"Already this year six motorcyclists have died on Waikato roads while another four have suffered life-altering injuries before these latest incidents.
