A report presented to the board said Green intended to visit the woman after his release and he knew her business address.
"She is regarded as a potential victim of criminal harassment by Mr Green," the report said.
The woman looked very much like Green's other victims, the report said.
The report suggested a further release condition should be that Green was banned from entering the area where the woman worked.
Green told the board the report was "fabricated".
However, the board agreed with the report and added the restriction to the 16 other release conditions.
Green has had five protection orders against him, eight convictions for criminal harassment and 29 convictions for breaching protection orders, the board said.
"He has a number of other convictions of serious offending including six for perverting the course of justice, perjury and threatening behaviour."
Green becomes fixated on women he sees on the street or in magazines, and harasses them by writing "abusive" and "frightening" letters and text messages, calling them and sitting outside their homes.
He was earlier denied parole because he was deemed a risk to the community.
The Parole Board earlier said that while Green did not have a release address, he would be prevented from living in or north of Auckland and would also be tracked using electronic GPS monitoring.
"On any measure the risks relating to Mr Green's release are high. He poses a significant threat to public safety. The board can only impose conditions best calculated to address those risks for the six months following Mr Green's sentence end date," the board said.
