Accent

I am just curious: will an expat get "native" accent in a couple of yrs - or have a different accent forever?

i think u can 'master' the native accent in a pretty short time if u keep repeating sentences/words/phrases like
rugby ball(eng)-rugby ba'll' where the double l is muted
also they dont use the R in some words u can say spa'r' again the r is muted and the actual word is spar
also they tend to speak very fast
anyways lots of differences between normal eng accent and the nz accent

asta stiu si eu din ce mam documentat + my ex was from nz so i started practising the language
