Brothels not playing fair with sex workers

"They wouldn't get away with it at McDonalds" - that's how one sex worker describes unfair employment conditions in some of the country's brothels.

Almost 20 years since New Zealand became the first country in the world to decriminalise prostitution in 2003 - there are claims that sex workers are facing workplace exploitation.

Otago University researcher Claire Weinhold looked at the way brothels are running their businesses and tells Karyn that many were found wanting.
