Two pair were spotted train surfing outside Manor Park Station, north of Wellington on the weekend.
A Russian tourist, Alexey Zhavoronkov, captured the footage while he was with his family on the road between Upper Hutt and Lower Hutt.
“We’re originally from Russia and this kind of madness is more like normal there … it was a shock to see people here doing it. It’s really dangerous … it was scary,” he told NZ reporters.
The footage went viral online and both police and rail authorities have condemned the irresponsible behaviour.
The footage has been given to police and they are currently searching for the two teens.
