This would be a good topic for the expats who have moved to NZ - just exchange Christchurch for NZ - what traditional foods have you found/liked? Are there any?
As an NZer from one of the rural provinces I would sadly admit the first 20 years of my life were, cuisine-wise, not very interesting. Potatoes, meat, over-cooked vegetables. Maybe apple pie, or apple/blackberry pie in season, icecream, for dessert. In those days, Friday night was fish and chips night, eaten at the beach when weather allowed.
My first trip to Australia - Adelaide and then Sydney with its diverse population - was the first time I had any foreign/ethnic foods.
I'm struggling to think of a genuine NZ traditional meal that I miss - apart from a good meal of crayfish (red rock lobster). NZ lamb is popular with some but never appealed to me personally.
Over to the experts!
