A sexual violence expert is calling for better education around sexual consent and relationships for men and boys because of prevailing offending.
New research shows the rate of New Zealand women facing sexual violence from a partner - one in six - has been mostly steady for the past 80 years.
The research, published in the journal Social Science & Medicine, also found one in five children experience sexual abuse, and one in 14 people experience non-partner sexual assault.
The study's lead researcher, Auckland University associate professor Janet Fanslow, said the offending was mostly because of a failure to involve men in preventative measures such as better education around sexual consent and healthy relationships.
