I don't know if any of this will be of help, but you might want to check out http://www.allthingstartan.com.au/ and http://www.celticaffairs.com/Highland%20Dress.htm. They appear to be kilt makers and band suppliers who have a selection of sporrans.

I also came across this site: http://www.nzs.com/business/shopping...-and-regional/ . It lists "ethnic clothing suppliers" in New Zealand. There appears to be many, many kilt makers and kilt suppliers there, including Dunedine Direct, which claims to be the only southern hemisphere kilt makers who hold the Scottish Qualifications Authority Certificate.

Anyway, I hope something there might be of help in your search to shop a little more close to home.
