"New tools to monitor criminals on home detention are closer to introduction, after successful tests of the satellite-based technology on Corrections Department staff. The department, in conjunction with home detention monitoring contractor Chubb NZ, has been testing voice-verification and global positioning system technology to either replace existing monitoring systems or use alongside them. Officials also plan to use the technology on high-risk child sex offenders who are subject to extended supervision orders, and on some offenders on parole. Laws passed last year allow for supervision of people who have offended sexually against children for up to 10 years after their jail term has ended."
