The Police Minister says research has been done on how to establish a sex offenders register in New Zealand.
Police and the Corrections Department are working on the proposal and legislation enabling a register could go to Parliament before the election.
Police Minister Anne Tolley says they've had a look at problems that were identified when former ACT MP Deborah Coddington tried - and failed - to establish such a register a decade ago.
"Certainly had a look at that. I've looked at other jurisdictions and we've tried to learn from that."
Ms Tolley says police and corrections are already sharing information around the issue.
"I'd like to see the legislation in the house before the election but it's a pretty full programme. It will work its way through the Cabinet process."
She says the register would be administered by police in conjunction with the Corrections Department.
Deborah Coddington is welcoming Anne Tolley's move.
There have been arguments that the register will be used by vigilantes to attack the sex offenders.
But she says the register wouldn't be a wholesale release to the public.
"I think that people like school principals, police, those sort of people will always be responsible with this information and it will no doubt keep a lot more children safe."
But the latest bid has already fallen foul of the Greens.
Co-Leader Metiria Turei says her Party's never supported a register in the past as they don't think it's the way to provide safety for families and children.
"It is something of a distraction from what's really needed which is investment in families and children, investment in services that protect against family violence."
