Kiwi fruit is naturally a very common feature in supermarkets.
There are a few other foods that seem to be typically Kiwi. One of my favourites is the pineapple chunks in chocolate. Yep they are as delicious as they sound and are one of the most popular things in all the sweet isles. There is also Hokey Pokey. This is a flavour of ice cream invented in New Zealand which has a sticky caramel honeycomb flavour and chunks of hard caramel in it. I haven't had a chance to try it our yet but (purely in the interest if science you understand) I will be testing it in the near future.
