A judge has described the actions of a man police have dubbed New Zealand's most dangerous stalker as abusive, sinister, threatening and frightening.
Glenn Carlionne, 42, who goes by several other names, was jailed for two-and-a-half years when he appeared at the North Shore District Court after admitting to two charges of criminal harassment.
He has amassed more than 200 convictions since 1987 - many of them for stalking at least a dozen women.
Carlionne was released on parole following a lengthy prison sentence in November last year, despite the Parole Board assessing him as being high-risk.
At the time, the Department of Corrections said he was subject to conditions which were to be monitored until May this year and that he would be held to account if he did not comply.
Carlionne was arrested again three weeks later for stalking three women, though one charge was later dropped by police.
During sentencing, Judge Phillippa Sinclair told Carlionne his narcissistic behaviour is of grave concern and his offending is escalating at a worrying rate.
"You have maliciously targeted and preyed on these innocent young women. It appears you went to some lengths seeking out the victims' contact details.
"And not only did you make frequent and numerous contacts with the victim, but the content of your contact was abusive, sinister, threatening and frightening."
The jail term is Carlionne's fifth prison sentence.
