"This provides an excellent mechanism to wrap around support and provide early intervention."
His report is one of a series commissioned by the inquiry founded by entrepreneur Sir Owen Glenn. The inquiry's final "blueprint" for tackling family violence is due late this month.
It comes two weeks after a ministerial forum on alcohol advertising and sponsorship chaired by former rugby league coach Graham Lowe reported to ministers on possible sponsorship restrictions.
The 25 men and one woman told Dr Roguski that alcohol "triggered the violence" and was a way to cope with problems such as financial stress.
"You start drinking more and you start conjuring up ghosts or whatever you want to call them. And you start taking it out on your partner," one man said.
Another said: "With alcohol, you don't know what you're doing."
The report found that almost all the perpetrators had been victims of family violence in their own childhoods.
"It was a learned response," Dr Roguski said.
One man told him: "My dad taught me a man is angry, aggressive, abusive, violent. That's the role model I grew up with. So I'm thinking, how are you supposed to be when you become a man? You don't want to look weak. You don't want to seem soft. Your reputation is everything."
Dr Roguski found that both this and the attitude to drinking were a kind of "distorted masculinity", and recommended banning alcohol sponsorship of sports, music and the arts. He found that the men stopped being violent only when they found other men who had been through similar experiences.
He recommended training former perpetrators and community leaders as "non-violence champions" who could be called in when police first attended a domestic incident and might order the perpetrator out for a few days.
Alcohol Healthwatch director Rebecca Williams said there were indications that Mr Lowe's ministerial forum may have recommended restrictions on alcohol sponsorship, possibly in line with a French law that bans broadcasting of alcohol brands and images.
But Distilled Spirits Association chief executive Robert Brewer said the French law had not reduced harmful use of alcohol.
Justice Minister Amy Adams said a decision on when the report would be released and the Government's response was yet to be made.
Perpetrator report
What is this report based on?
Dr Michael Roguski interviewed 25 men and one woman who had perpetrated family violence. Most (14) were now over age 45; 18 were Maori.
What did it find?
Almost all (22) had been exposed to family violence themselves as children; they saw violence as normal for men and "don't want to look weak"; alcohol and other drugs stopped half of them from doing something about it until they "stumbled across" others who had stopped.
What does it recommend?
Banning alcohol sponsorship of sports; training former perpetrators and community leaders as "non-violence champions"; and connecting perpetrators with the champions as early as possible, for instance in houses for men issued with police safety orders.
