The NZ short front vowel shift
New Zealand English has undergone a chain shift of the short front vowels. KIT centralised toward schwa, which made room for DRESS to rise toward [ɪ], which made room for TRAP to rise toward [ɛ]. The result is a vowel system noticeably different from British RP, and the famous Kiwi pronunciation of "fish and chips" as "fush and chups".
