"But with things like It's Not Okay In Whangarei and huge Government input into raising awareness of the issue, more and more people now come forward to report family violence to police.
"And that's great, New Zealand is starting to take more responsibility for the care of its families."
Most domestic violence involved male brutality towards women or children, but there were cases of violent women.
Ms Pepene said a positive was that Northland groups working with domestic violence were seeing more self-referrals from men wanting to break the cycle.
"The perpetrators are starting to step up to the plate, too, and are seeking help before they go through the court system. That, in itself, is reflective of people wanting to make changes and help themselves," she said.
The violence could only end if it became a topic people openly talked about and everyone stood up to say it was not okay.
"Family violence has got to be as common to talk about as fire safety or brushing your teeth ... we've all got a part to play in it by taking an interest in what is happening in your neighbourhood, your community, and reporting any family violence."
Nationwide, police were called to nearly 90,000 domestic-violence incidents in the past financial year, more than 240 a day. About as many calls were made to the Women's Refuge hotline in the same period with nearly 86,000 crisis calls received. Police investigated 23 family violence deaths.
