Here in New Zealand, a Mince Pie is a pie containing mince meat. The type of mince pie you're talking about is called a Christmas Mince Pie or a Fruit Mince Pie.

We also have chips (the type you might have with a hamburger), and chips (the type you might eat cold from a bag). If you need to clarify which one you mean, for some reason "potato chips" exclusively means the latter (for the other type you might say "hot chips").
