A two-time rapist has received an indefinite jail term for the attempted sexual violation of a teenage girl.
Justin Ames Johnston, 41, has been sentenced in the High Court at Wellington to preventive detention with a minimum non-parole period of six years.
He has also received a concurrent sentence of six months' for threatening grievous bodily harm to her father, who chased him at the scene.
In December last year, Johnston was found guilty of attempted sexual violation of the teenager.
The father of the girl discovered Johnston in the backyard the Upper Hutt property where the 16-year-old was alone in a sleepout.
