Women's rights campaigner and academic Dame Dorothy Winstone has died.
Winstone fought battles over equal pay, women's right to serve on a jury and the establishment of a national women's hospital.
She also sat on the Royal Commission on Contraception, Sterilisation and Abortion which ran from 1975 to 1977.
The Dorothy Winstone Centre Theatre at Auckland Girls' Grammar was named in her honour in 1988.
Winstone's involvement with the school was always "unstinting", principal Liz Thomson said.
"She has been amazing, she has been involved in many organisations, I guess she has been a feminist in a way that we like to encourage our girls to be," she said.
"She has been a really great role model for the school."
Winstone attended Auckland Girls' Grammar from 1931-1935 and Thomson said it was only in the last year that she had stopped attending functions.
"She was our most committed old girl."
A memorial will be finalised on the school grounds in her honour in the coming weeks.
Winstone was made a dame in 1990. She died on April 3.
She had four children, 20 grandchildren and 12 great grandchildren.
A service will be held in Auckland on Wednesday.
