New Zealand English has developed as a unique variety of English with its own vocabulary, accent, and history. It originated from a mixing of dialects including Cockney English and other British regional accents. NZE is distinguished by its pronunciation of vowels, with shifts in vowel space and the development of new diphthongs not found in other varieties like Received Pronunciation. One such new diphthong is the pronunciation of 'me' as a two-part vowel, differing from other forms of English.
