Catching illegal sex workers 'difficult' - Immigration NZ

Immigration authorities say finding foreigners working illegally in the sex industry is being limited by how hard it is to catch them in the act. New Zealanders have been able to work as prostitutes since 2003, but it is still illegal for immigrants to. The Prostitutes Collective says because of that, they are being bullied, exploited and forced into work by unscrupulous brothel owners and clients.
