New Zealand is to host a meeting of attorneys-general from the United States, Canada, England, Wales and Northern Ireland next week.
Attorney-General Christopher Finlayson says the meeting on 8 May will focus on prosecuting crimes of violence against women and children.
He says the meeting will also discuss gun violence, strengthening co-operation in civil and commercial matters and support for victims of crime.
There will also be a wider meeting of law enforcement agencies that focus on international crime, he says.
