It cited sources as saying the women were unhappy with the decision because they attended meetings at Bowen House and were told to contact the party if they were visiting.
The male staffer had also been barred from a building where some of the women worked, and - in a separate letter - general secretary Andre Anderson had asked a witness in the case to stay away from Bowen House, Stuff said.
Labour Party president Nigel Haworth declined to comment today, saying the matter was under appeal.
Parliament's Speaker's, Trevor Mallard, has oversight over security at the precinct and described the call for people to stay away as "inappropriate".
"Any person employed at Parliament should make a formal complaint to their supervisor, the general manager or me if they feel unsafe," he said.
"I also strongly urge anyone who has been assaulted or has witnessed an assault of any sort to contact the police."
Issues have also been raised about the appeals process since it was announced last month, with National Party deputy leader Paula Bennett saying complainants had told her it was not victim-led and sources telling the Herald they had lost faith in the party's efforts.
