New Zealand Sign Language (NZSL) is the language of New Zealand's Deaf community.
It's a visual-gestural language with its own grammar and is capable of expressing any ideas like any other language. It is not a literal translation of spoken or written English.
NZSL is used by 20,000 New Zealanders. Approximately 4,000 of these are Deaf people who use NZSL as their first or preferred language.
