Risk-based registries reflect the determined dangerousness of registered offenders, while sentence-length-based registries reflect the severity of the crime.Offense-based registries reflect neither the dangerousness of registrants, nor the severity of their crimes.
However political lobby group the Sensible Sentencing Trust has criticised the proposed register for its lack of public access.
According to the Minister of Police and Corrections Anne Tolley, Cabinet has agreed to allocate $35.5 million over the next ten years for the technology component of the register and initial ICT work is underway as of 14 August 2014.
It will be managed by the New Zealand Police and information will be shared between the Police, Child, Youth and Family, the Department of Corrections, the Ministry of Social Development, and the Department of Building and Housing—government agencies which deal with child safety.
Like the Australian and British registers, the New Zealand sex offenders register will not be accessible to the general public but only to officials with security clearance.
Offenders are monitored for eight years, 15 years or the remainder of their life (four years or 7½ years for juvenile offenders).
On 1 March 2011, there were 12,596 registered offenders across Australia.
In many jurisdictions, registered sex offenders are subject to additional restrictions, including on housing.
Those on parole or probation may be subject to restrictions that do not apply to other parolees or probationers.
UK, Canada, and Australia have adopted either risk-based- or sentence-length-based registry schemes. states applying risk-based systems are pressured by the U. federal government to adopt offense-based systems in accordance with Adam Walsh Child Protection and Safety Act.
In the United States, the vast majority of the states are applying offense-based registries, leaving the actual risk level of the offender and severity of the offense uncertain. Studies has shown that actuarial risk assessment instruments consistently outperform the offense-based system mandated by federal law.
Sometimes, these include (or have been proposed to include) restrictions on being in the presence of underage persons (under the age of majority), living in proximity to a school or day care center, owning toys or items targeted towards children, or using the Internet.
