Video footage has emerged of a motorcyclist's wild ride across almost the entire length of the Auckland Harbour Bridge on the rear wheel of a bike.
The clip, which was captured during a sunrise, attracted more than 1000 views since being shared on Instagram this morning. It has since been removed.
The NZ Transport Agency has condemned the motorcyclist's behaviour and police are investigating.
The identity of the daredevil motorcyclist, clad in only a black T-shirt, light blue jeans and black sneakers, remains a mystery, but it appears the bike is a Harley Davidson.
NZTA, which operates the Auckland Harbour Bridge, condemned the motorcyclist's behaviour.
"It poses a huge safety risk for the motorcyclist and all other road users. It is reckless and dangerous and we'll support the police in any way to identify the person or persons involved," said Auckland Transport operations manager Rua Paul.
"We have video of all those involved and will pass it on to police."
Police are also making inquiries.
"The behaviour of this motorcyclist is extremely dangerous and could have fatal consequences," said Waitemata Sergeant Richard Byrne.
"It shows a complete lack of regard for their own safety and the safety of others."
People who witnessed dangerous behaviour on the roads should contact police, he said.
Byrne said anyone who had information about the motorbike stunt should call police on (09) 477 5000 or contact Crimestoppers anonymously on 0800 555 111.
The Herald has also contacted the AA for comment regarding the video.
The video comes as the road toll continues to climb.
