About 10 local and international media filmed and photographed the game, with images expected to be broadcast worldwide.
Romanian team management also took time out before Saturday night's game against England to see a lighter side of rugby. Team police liaison officer Sergeant Hugh Tait, of Dunedin, said: "They thought it was great".
Nude Blacks captain David Bourke said the team was "keen to get the season back on a roll" after a loss to a Spanish women's team two weeks ago.
The Nude Blacks won six tries to four, he said.
