(work in progress)
Shopping in NZ supermarkets does not give you the choice of many wine countries, usually Aussie reds, South African (cheaper ones), sometimes a bit from Chile and of course home wines. So for new immigrants especially from the UK this is a severe disapointment, where one has the world (literally) of choice, but one adapts. We have settled mainly on only drinking NZ wines, not out of patrotism, just we have discovered what we like and what are the best.
