I have a New Zealand accent. Despite living in Scotland for ten years, I can't do a Scottish accent for the life of me. I have picked up on a few phrases, though. As for simple words like 'Aye', I was already saying them in NZ, so that doesn't count.

There are too many phrases over here to even attempt to list them. Same for NZ, really. I wouldn't know where to begin, and I know that there are a lot of sayings that are new in NZ that I don't know personally because I wasn't around when they became popular (eg. nek minit).
