Sign Language Becomes Official in New Zealand

See this article by that title. It begins:

New Zealand's parliament has voted to make signing the nation's third official language.

New Zealand Sign Language, different to signing in other countries and used by about 28,000 people, joins English and Maori as a language which can be used in legal proceedings.

The nation joins several European countries and North American states and provinces in giving official status to signing - predominantly used by the deaf and hearing impaired.
