I am a New Zealander and apparently we also say pin when we mean pen. I thought the broad NZ accent wasn't something that I was really afflicted with, but in an airline lounge in Seoul I was disavowed of this notion when the English businessman whom I was trying to borrow a pen from couldn't understand why I would expect him to have a pin (or indeed how I proposed to fill out a form using one).
As a kiwi who moved to Australia as a kid, the pin/pen and six/sex (Australians make the number six sound rather hilarious) dichotomy was a constant source of amusement to me :)
Want some chups from the fush and chup shop bro? Or I'll just pop down to the dairy instead ;)
I once was working in a deli in Ireland and I got a customer who asked me for a rep (or was it a rap?). I was seriously puzzled until one of the people who was with her told me she wanted a Wrap and she was from New Zealand.
Kiwi english is one of the most interesting english accents to me. It seems like you guys have undergone a whole new vowel shift.
