The only one that NZ serves that I haven't been to (yet ) is Norfolk Island, but also plenty others that NZ doesn't serve - will take more time and effort to get to.

I do have a soft spot for Cook Islands - I won't go into why.

Actually NZ have for the past 18 months published a wine guide every 6 months and this is sometimes available on the longhaul flights in business premiere (it should be on every flight but sadly not ). The wine guide lists most of the wines NZ uses in business class, although only some of them will be onboard (eg IIRC it lists about 4 pinot noirs, only 1 of which will be on any given flight) and there are sometimes substitutions.
