The biggest difference in what's going on in New Zealand versus the rest of the world, aside from the decriminalization of sex work, is that sex workers were actually part of the decriminalization process. There was a provision in that legal change stating sex workers would be part of an evaluation committee, and in 2008, they were, they were a part of the committee determining whether or not decriminalization worked. They are continually regarded as stakeholders - in their communities, but also in the legal process. That's such a different way of operating.
In New Zealand, sex workers are regarded as workers, as people who are members of the community, people who have a stake in the community - not just in the workplace, but in the broader community. They aren't objects to be controlled and regulated. They are not collateral evidence of a crime. They are human beings.
Most of the time, people are not actually concerned with prostitution and sex work. They're concerned about seeing people who they think are prostitutes and sex workers in their community. Sometimes this just comes down to profiling, the feeling of "I don't want someone who looks like that in my neighborhood." We need communities and neighbors to regard sex workers as part of the community and fellow neighbors. But that's really difficult. There's certainly nothing supporting that.
