In the latest New Zealand edition of the Australian Women's Weekly, Davidson has revealed her abuser was a relative.
"I was molested from the age of 7 to 9 by a family member and it was heavy but I moved through it," Davidson said.
"It is just one of the many stories that make me who I am."
Davidson kept the abuse quiet from her family until she was 24, breaking her silence after another family member revealed the abuse she too had suffered.
"I felt like I finally had a safe place and someone to talk to about my story, otherwise I'm not sure I would have told anybody. Because of her I managed to tell my husband and my mum."
Davidson entered Parliament last month after the resignation of long-standing Green Party co-leader Russel Norman.
Carter ordered her out of the debating chamber just five days into her parliamentary career. Her rapid ejection made international headlines.
"My family was so proud of me," she told the Australian Women's Weekly. "They sent me messages saying 'We are so proud of you entering the house to get kicked out of the house'.
Key eventually apologised for his inflammatory comment.
The latest edition of the Australian Women's Weekly is on sale today.
