Detective Sergeant James Watson, of North Shore, said a young Devonport woman had come forward with a further complaint against Green at the weekend after seeing his photo in the Weekend Herald. "Every person that comes and makes a complaint we can go and lay more charges," Mr Watson said. "He's got 227 convictions."
The woman had been "freaked out" by constant harassment similar to what was alleged for the 19-year-old, he said. The court heard that teen had left her family home and changed her phone number to avoid Green.
He had been out of prison for only a week when he started contacting her, said the police prosecutor in court.
The prosecutor said the officer in charge of the case had described Green as "the most dangerous stalker in New Zealand at the moment".
Detective Sergeant Chris Power, of Christchurch, said police had also been in touch with three local women.
He encouraged any other alleged victims to come forward. "Anyone that's received any mail, messages or photographs from a person calling himself with a first name of Glenn and any name after that, wanting to have a meeting, get in touch with me directly."
Green has used several different names, including Glenn Mike Carlionne, Glen Dallas Goldberg, Glenn Richard Charles Holden and Glenn Colcord.
Mr Power said Green had apparently texted, phoned and posted letters to home addresses.
But the one South Island complaint that had already been evaluated did not in itself amount to a criminal offence, and police were keeping an open mind as to who could be behind the other cases, though Green was on a list of suspects.
