New Zealand's sex industry prior to reforms in 2003 has been described as a dangerous environment that lent itself to violence, exploitation and coercion.

But now, prostitutes can go to the police for help rather than facing arrest. Their lives are no longer blighted by convictions for soliciting and they have the right to object to any ill treatment.

She wanted to run a business that helped the women who worked there achieve their goals in life.

"I would hope that they were with me for a certain period of time and that I was like a stepping stone to the next goal, but while I've got them there I'm trying to give them some really amazing life skills."…
