Maggie Barry has been hit with fresh allegations of bullying, including that she referred to department officials as her "hired help".

The North Shore MP spent the weekend denying she bullied two staff members, saying investigations found no evidence of bullying in her office.

Now another former staff member has spoken out with fresh allegations of a "toxic" workplace - although Ms Barry has again rejected those claims.

Speaking to Newshub anonymously, the source said Ms Barry would lash out at staff and that she was "totally intimidating".

"She would attack and belittle your work in front of other people."

They worked in her ministerial office, and said staff would break down in tears.

The staff member said Ms Barry would treat everyone below her station with "utter contempt" - including referring to officials in her ministerial departments as "hired help".
