The Corrections union insists corrupt staffers are few and far between, and some are even forced to go down the wrong path. 

14 staff from Mt Eden and Auckland South Corrections facilities have been arrested. 

A dozen are charged with accepting bribes, and others with conspiring to supply a Class A drug —namely methamphetamine— to prisoners. 

Corrections Association President Floyd du Plessis told Mike Hosking it's not the norm, but in the past, some staff have been coerced by people who monitor their behaviour and learn about their personal lives. 

He says in the past, staff have even had people turn up at their house and intimidate them, and have succumbed to that pressure.
