An accused child rapist is one of a growing number of people able to flee criminal charges after cutting off their electronic bracelets.
The man, 43, got married while he was awaiting trial and obtained a passport under his wife's surname. He managed to flee to Australia without being detected.
Officials blamed one another for the botch-up, but an internal review found a Ministry of Justice employee was to blame after simply ticking the wrong box on a form.
A police source said the number of offenders cutting off their monitoring bracelets while on bail and leaving New Zealand was increasing.
