Tasmania's premier has pledged an independent review into how the findings of a sexual harassment claim by a female public servant were aired in a parliamentary hearing before she was told.

The woman, named only as Alysha to protect her privacy, alleged she was referred to as a "Japanese f*** doll" by a senior manager in 2019 while working at Ashley Youth Detention Centre.

She learned her accused harasser had been cleared when it was revealed during parliamentary budget estimates hearings on Monday.

"In terms of what occurred ... with Alysha here in the chamber, I want to apologise for what was a misstep," Premier Peter Gutwein said on Tuesday.

"There will be an independent review conducted at arm's length from government of the process that occurred. I'd expect that to be completed within a period of 30 days."

Alysha says she was told a few months ago that a determination in her complaint had been reached but she did not have the right to know as it was a "matter between the employer and the accused".

She was physically ill after listening to the estimates hearing online having being tipped off by a friend they were talking about her.

"The way in which this outcome was revealed to me was nothing short of negligent," she said.

"(Monday) was one of the most shocking days of my adult life."

Mr Gutwein and Alysha will meet on Wednesday. She has asked to be told the reasoning for the finding and wants drastic and tangible reforms to the complaints process.

"If being referred to as a Japanese f*** doll in a room full of my senior colleagues does not constitute a breach of the state code of conduct, I cannot for the life of me understand what would," she said.

"If that does not meet a breach of the ... conduct, then that document needs to be burned."

Mr Gutwein said State Service head Jenny Gale, who told the estimates hearing the accused had been cleared of breaching the public service code of conduct, had also apologised to Alysha.
