I don't know if the brand is available outside New Zealand, but it is
"fresh∗paper" brand OCCASIONS Photo & Presentation paper. 180 gsm glossy
paper, glossy on one side ffairly rough on the other, made in China. I
haven't had access to a mass spectrometer for several years so I don't
know what the coating is, I just assumed it was Kaolin. There is a
website listed
http://www.freshprintcompany.com but I can't connect to it.
