Privately run prison doing poorly - Greens
Escapes, wrongful detentions and wrongful releases are happening up to three times more often at the privately run Mt Eden prison than in Corrections Department-managed institutions, figures show.
Information obtained by the Greens under the Official Information Act for the 18 department-run jails has been compared to the first performance report for Serco.
Between last August and this April, Corrections prisons had six escapes, 10 wrongful detentions and six wrongful releases.
Serco had one escape, three wrongful detentions and three wrongful releases.
The errors were not much higher for Corrections despite its total muster of 8698 being nine times the 966 inmates at Mt Eden.
The Greens said the figures showed Serco was doing poorly.
