Kiwi actress Rebecca Gibney slams media report on grandfather's alleged sexual assault of her and her mum

New Zealand actress Rebecca Gibney has expressed how "saddened" her and her family are from a media report her grandfather tried to sexually assault her as a child.

Gibney took to Instagram today after sensitive information she had shared with ABC News for an upcoming interview, was reported by The Daily Telegraph without her knowledge. 

In the interview, Gibney travels home to Wellington to discuss her father and grandfather with host ABC Julia Zemiro, who Gibney later describes as "extrememly sensitive and wonderful".

"I have not seen the show and I have not been contacted for publicity nor have I given any interviews for the episode," wrote the actress, who is a public campaigner on domestic violence .

Gibney reportedly told Zemiro of how her 12-year-old self fought off her maternal grandfather's advances. 

The Daily Telegraph also reported that her grandfather, who is now deceased, sexually abused her mother between the ages of two and 15 years.

Gibney posted that using her family's story to sell newspapers was not on.

"My family and I are extremely saddened that I was not contacted or informed that this article was coming out," she said.

The ambassador for Share the Dignity said that if her openness about growing up in an abusive home can help others, then her job is done. 

"For those that have suffered any kind of abuse, please know that you can get help and move forward. My family and I are a testament to that," she said.
