The New-Zealand registry is considering including Maori characters in .NZ domains.
New-Zealand's namespace is no different to any other. It wasn't designed for anything other than the basic English alphabet and its non-accented ASCII characters.
Want to register a .NZ domain? Your only possible choice is between the 26 letters of the Latin alphabet, the standard digits and the hyphen sign.
But New-Zealand's indigenous people, the Maori, have extra characters in their alphabet. The Maoris' long vowels, such as hyphenated a or e, are necessary to correctly spell certain words but cannot currently be included in a .NZ domain name.
The country's registry hopes to rectify this. A working group has been set up to work on implementing 5 Maori characters as IDNs (Internationalized Domain Names): hyphenated a, e, i, o, u. And a public consultation is underway to determine how best to deploy these IDNs.
