Feminists are seeing red over a rule forbidding pregnant or menstruating women attending a Te Papa exhibit.
A rule inviting regional museums to go on a behind-the-scenes tour of some of Te Papa's collections stated that "wahine who are either hapu [pregnant] or mate wahine [menstruating]" should not attend, the New Zealand Herald reported.
The rule was imposed to respect Maori beliefs surrounding the Taonga Maori collection, Te Papa spokeswoman Jane Keig said.
If an object is tapu it is "forbidden" and in Maori culture it is believed that if that tapu is not observed, something bad will happen.
It was expected that women attending the tour on November 5 would be honest about their conditions.
However, Deborah Russel, feminist blogger on The Hand Mirror blog, said the policy had no place in modern society.
"I don't understand why a secular institution, funded by public money in a secular state, is imposing religious and cultural values on people."
The state should not impose other people's cultural practices on people in general, Ms Russel said.
