Air NZ has developed a real knack for clever PR stunts. The latest is having their staff, covered in nothing but body paint, do the in-flight safety video. Classic.

This year’s cheeky ad campaign and the safety video, “Bare Essentials of Safety,” have brought Air New Zealand a lot of attention that it hopes will put lots of bottoms in seats.

The commercial, “Nothing to Hide,” has been viewed nearly two million times on YouTube — the most-viewed clip ever to come out of New Zealand, Steve Bayliss, the airline’s marketing manager, said by telephone Monday.

Each video took a day to shoot and cost about 10 to 15 percent of the cost of a major brand commercial, Mr. Bayliss estimated, since there were no actors to pay. The Air New Zealand staff members did not receive extra pay, just increased exposure.
