Thanks to everyone for your supportive comments on my New Zealand rip off merchant!
As I mentioned on my earlier post, I contacted the Trade Me site to complain and received the following reply;
"Hi Clare, thanks for contacting us.
I am the Liaison Officer for our Trust and Safety team and I specialize in working with brands or their representatives to help them to protect their intellectual property on our site.
I have removed the reference to your brand from the below listing and sent a warning to the seller.

So, the issue has been resolved and I am happy :)
