The Fiji Women's Crisis Centre coordinator, Shamima Ali, says she believes a return to special village laws will make women and children more vulnerable.
The proposed by-laws, reported in local media, allow controls on dress and impose curfews.
Miss Ali says the rules in place in colonial times also allowed corporal punishment, and says she has met a man who was flogged for committing a rape.
She says the by-laws would also place restrictions on women's behaviour.
"You know that does have, in a society that is already very patriarchal and gender biased and where there is a lot of gender inequality, these kind of by-laws would tend towards increasing the problems that we already have in terms of violence against women, access to justice and women's access to health and things like that."
