Welcome Stephen!
Dunedin is a lovely city, isn't it? Though you're likely to be freezing a few appendages off down there this time of year. My wife and I immigrated to NZ in 2002 and would still be there today if it weren't for some health issues in the immediate family back here in California. We lived in Hamilton until 2008, but saw nearly every square inch of that country in our time there.
I purchased my first Alembic while living there- I got it from a fellow club member here on the forum. People will ship to NZ I'd suggest you hang around for a spell- something will pop up in short order.
The closest Alembic dealer is Bass People in Sydney. I spoke with the owner, David Burgess, several times while living in NZ and he is a good guy to deal with. I also know that several places in the States will ship down to NZ- Bass Northwest usually has some decent used Alembics in stock.
Take a look through the showcase thread and see what style bass tickles your fancy. Plenty of body shapes and electronics packages to choose from. There are plenty of friendly people who post here who are willing to help too.
Enjoy~
