Hi Dylan! Thanks
I'd check out the CNZ facebook group and introduce yourself there. A lot of photographers post and make a general inquiry about shoots and who's interested, with mixed results, but I'd recommend asking individuals directly as well. A lot of the time people seem respond well to a general call but not actually follow through, I think just because most of us are super disorganised! You'll have more luck asking people directly
There are quite a lot of cosplayers in Welly, and HEAPS in Aucks, so start with the fb group and check out the cosplay new zealand tag on tumblr as well. I spam that tag a lot though, so apologies in advance...you might have to do some sifting through all my crap! But yeah, basically just ask people
Just a heads up though, cosplayers are usually NOT models, and very frequently need a lot of direction. Bear that in mind, or you might end up pretty frustrated (I don't know what you're used to - ignore if not applicable).
