Tolley said the system in the past could inadvertently force victims to bear the burden of keeping themselves safe.
The trauma of violence could be compounded by further upheavals, such as disruptions to housing, jobs or schooling, she said.
"Evidence suggests that removing perpetrators rather than victims from family violence situations can help prevent homelessness for the victims and creates less disruption in their lives."
The funding will focus on Christchurch and Waikato, where domestic violence programmes are being trialled.
The new initiative will complement another scheme which helps victims stay safe in their homes by installing new locks and alarm systems.
Around 750 victims have had their houses fitted with security features under the $3.6 million programme.
In 2010, police introduced special orders which required abusers to stay away from the family home for up to five days.
In some cases, the person had nowhere else to stay.
