TVNZ's chief executive has ordered a review into the organisation's hiring process, following the abrupt departure of Breakfast host Kamahl Santamaria.
Santamaria quit after 32 days in the job, after a complaint was made over his behaviour towards a female colleague.
There have also been reports he acted inappropriately - including unwanted physical advances and sending lewd emails - while working for his previous employer Al Jazeera.
In an email to TVNZ staff, chief executive Simon Power said the organisation's recruitment policy had not been followed consistently and needed to be reviewed.
"We do not tolerate any form of harassment or inappropriate behaviour in the workplace. We're committed to providing a working environment that is inclusive and respectful," the email said.
"I've asked senior employment lawyer Margaret Robins to review our policies, processes and practices to ensure they are fit for purpose and appropriately robust. When that review is complete I'll share any recommendations with all TVNZers."
It was of utmost importance that concerns over the behaviour of team members was taken extremely seriously, treated confidentially, and investigated swiftly, he said.
Support and care for individuals who raised concerns was the top priority, he said.
Earlier this morning, Minister of Broadcasting Kris Faafoi said he had sought an assurance from TVNZ that appropriate recruitment processes had been followed.
"I think those things are important to make sure those processes are followed, it keeps the company safe," he said.
"I've sought an assurance, we were given a no-surprises update, I'm not going to get into the detail of it. It's not for the broadcasting minister to get involved in HR issues within the public broadcaster."
He said at the time he was hoping to hear back within two or three days.
