The price tag of keeping people in jail is increasing, even as New Zealand’s prison population drops significantly, NZ Herald reports. Each person behind bars costs roughly $150,000 a year – that’s up $30,000 on the 2018/19 financial year. The figures have prompted the Green Party to call prisons “an expensive failure”. Meanwhile, the Corrections Association is questioning the taxpayers’ value for money and accusing Corrections Minister Kelvin Davis of playing politics over prisoner numbers.
