Well its legal in NZ, so probably will see alot more of them now, yes they are quite easy to pick out.
The first time I ever saw one was when I was in Sydney, Kings cross, notorious for them, I was shocked, they even came up and approached young men who had girlfriends with them, that really bothered me. I could not believe what they were wearing, but then I was just a young naive 20 yr old then.:)
