A Facebook group dubbed Perth NZ bombing has posted a video of someone in Wellington jumping off the top of a crane and into the water below.
The stunt, the video of which was posted yesterday and has since been viewed 86,836 times, has been condemned by police.
The jumper, who has not yet been identified, survived the 30 metre plunge off the Hikitia floating crane at Taranaki Street wharf.
In the post on Facebook, the group says: "This should go viral bombz."
Police today questioned the judgment of the jumper. "The most concerning thing is the safety issues. Climbing on to that boat with all the associated equipment on the deck etc, and then clambering up the crane to the peak. The potential is there to fall down on to the crane," Inspector Dave Rose said.
"There is obviously potential there for serious harm."
Mr Rose said the fall to the water was between 30 and 40 metres.
"Had the person landed the wrong way in the water - it doesn't bear thinking about."While it may seem like a fun thing to do at the time, you would have to question the person's judgment and decision-making around going up there."
The jump divided visitors to the group's Facebook page. One person wrote that video was "mean" and the jumper's height was "off the hook".
Another commented: "What an idiot!! I knew someone that lost their life doing that from that same point.. Use your F**** brain!"
The video comes a week after two youths were caught "train surfing" on a commuter train in Wellington.
Mr Rose said now most people had access to smart phones, it was much easier to capture these incidents on film.
"I guess perhaps it's something that happened in the past that we just hadn't been aware of, or haven't been able to visually get an appreciation of.
"Now with modern technology it allows passers-by or members of the public to capture that."
He said Facebook and other social media sites made it easier to publish these videos straight away.
Mr Rose said police would be keen to talk to the person involved about their "decision making"and "putting themselves in harm's way". "There was the potential for things to go horribly wrong", he said.
