Social conservative group Family First wants New Zealanders to boycott upcoming R18 movie Fifty Shades of Grey, saying it "glamourises sexual violence".
The group's director, Bob McCoskrie, joins a worldwide backlash, including Malaysia's government banning the film, which claims the book and movie normalises violent and abusive relationships.
Outspoken critic and psychiatrist Miriam Grossman has been writing a "parent survival guide" for Fifty Shades of Grey and says the book and movie is harmful to teenagers.
"Fifty Shades of Grey teaches your daughter that pain and humiliation are erotic, and your son, that girls want a guy who controls, intimidates and threatens. In short, the film portrays emotional and physical abuse as sexually arousing to both parties," Dr Grossman says.
Mr McCoskrie instead wants people to donate what would be their admission fee to a local womens refuge.
"A woman who is humiliated, abused, controlled, entrapped, coerced, manipulated and tortured is somehow an 'empowered' woman. And a man who is possessive, controlling, violent, jealous and coercive is somehow showing 'true love'," says Mr McCoskrie.
"These are foul and dangerous lies.
"[It] simply glamorises sexual violence and should be rejected by everyone who is concerned about family and sexual violence."
The US National Center on Sexual Exploitation has launched a campaign against the movie, including making the website fiftyshadesisabuse.com, sponsoring the #50DollarsNot50Shades Twitter campaign and also encouraging families to donate instead.
The film is to be released in New Zealand on February 14 - Valentine's Day - and is R18.
