Max you have one of the best fine wine makers in your area. Brown Brothers. They make the worlds greatest Port. (IMHO) (BTW, my wine knowledge is up there with my brain surgery knowledge)
With only slight bias, New Zealand produces many great wines. Mills reef, Morton Estate, are a couple from near my home. There are many more around the rest of the country.
Picking up on selected blurb, Australasian wines are world beaters. Don't be afraid to buy local.
