Without words or even sound, members of the deaf community cheered Green MP Mojo Mathers as she made her history-making official introduction to Parliament.
Ms Mathers delivered her maiden speech with assistance from a sign language interpreter in the chamber - a first for the House.
"My election on the Green Party list under MMP means that the hearing-impaired, deaf and people with disabilities have representation in Parliament by someone who shares with them many of the same experiences and challenges that they face," Ms Mathers said.
"It is a huge honour to be representing this community in the House, and I take this responsibility seriously."
The public gallery was filled with deaf supporters, who were joined by MPs in applauding Ms Mathers by waving their hands - the sign language equivalent of clapping.
