How much should I tip in New Zealand restaurants?

Question

I know it's not mandatory but I'm unsure how much is appropriate to give for good, great and shoddy service.

Answer 1

Great service - 10% ish - depends, would usually round it up, i.e. if the bill was $110, make it $120

Good service - a few bucks, kind of depends as well on the individual person looking after your table

Shoddy service - not a cent and would tell them they were not great as well!!
