Buttock-baring behaviour has been banned at Machu Picchu after a nudie run landed one Kiwi tourist in trouble with Peruvian officials.
A YouTube video of two tourists streaking across the Incan ruins has gone viral after being picked up by Peruvian news outlet El Comercio.
The pair were arrested following the incident last year and a police report identified the alleged culprits as 30-year-old New Zealander Matthew Topp and 18-year-old Australian Liam Rudevies.
They were ordered to erase the offending images from the memory card of their camera, but someone else obtained and uploaded them, travel agency Fertur Peru Travel reported on its website.
According to a translation of the police report, it was "totally forbidden to take photographs of this magnitude".
The city of Cusco's regional director of culture also issued a statement saying park guards at Manchu Picchu and other historical sites would increase surveillance from now on "to avoid these unfortunate events that threaten cultural heritage".
It is not the first case of New Zealanders behaving badly overseas.
In 2012, a complaint was made to the New Zealand High Commission in London about the drunken antics of Kiwis participating in annual Waitangi Day events.
Expat Dylan Clements said the behaviour was an "embarrassment" to New Zealand, and claimed he witnessed participants urinating and vomiting on famous religious landmarks, including Westminster Abbey and the historic Jewel Tower.
In 2010, a documentary screened on German television about Kiwi tourists using Oktoberfest in Munich as an opportunity for binge-drinking.
Following the 2005 Anzac Day dawn service in Gallipoli, Kiwis and Australians raised eyebrows for their "party-like" behaviour, drinking alcohol and leaving the sacred site strewn with rubbish.
