They don't have to come from NZ to be drinkable - try an Adelaide Hills Sauvignon Blanc

Sauvignon Blanc does best in a cool climate and the Adelaide Hills might not be Marlborough with its ocean breezes but it does avoid the worst South Australian heat. A skilled wine maker can turn the benefits of lower over night temperatures into a tasty drop and the Ariadne Adelaide Hills Sauvignon Blanc 2017 proves that.
An $8.9 a bottle wine that more than holds its own compared to those Kiwis at a couple or three dollars a bottle more.

I gave it a score of 91 on my ratings - excellent value-for-money drinking.
