I'm not a native English speaker and the American accent is the most familiar to me.
I plan to visit NZ for a Working holiday program, but I'm concerned that I won't understand what they say. I can fully understand the North American speakers, but when I heard New Zealanders speak on TV, I couldn't understand half of it.
How to make sure that I will understand this accent and will it make my English worse for other places if I stay there long term?
Thanks
