New Zealand Sign Language (NZSL) is the main language of the Deaf community in New Zealand. It became third official language of New Zealand in April 2006 after English and Te Reo Māori on April 10, 2006.
NZSL is historically derived from British Sign Language (BSL). Both NZSL and BSL are unrelated to American Sign Language (ASL) which is historically related to Old French Sign Language.
