Labour and rape prevention groups are demanding urgent change to rape laws to give victims more rights.
Marches took place throughout the country at the weekend in response to a group of young Auckland men who boasted online about having sex with drunk girls, some of them underage.
Labour's Justice spokesperson Andrew Little says at present, the law makes victims reluctant to press charges.
He says the law assumes the victims of rape have done something wrong, and the rules around consent need to be revised.
Rape Prevention Education executive director Kim McGregor says only one in every 100 reported cases of sexual violence results in a conviction.
