NSW Premier Gladys Berejiklian will not discipline one of her ministers for dragging the harassment allegation against Luke Foley into the public domain against the wishes of the woman involved.

Ms Berejiklian on Friday said she was "disappointed" ABC journalist Ashleigh Raper had no control over the airing of the harassment allegation against Mr Foley by Corrections Minister David Elliott in Parliament last month.

But under repeated questioning at a press conference, the Premier refused to admonish Mr Elliott publicly and indicated there would be no consequences for his actions in terms of his role in her government.

"I am disappointed her ability to choose what she said, when she said [it], if anything was taken out of her control," Ms Berejiklian said on Friday.
