Minister for Children and Youth Affairs Katherine Zappone has met the board of Tusla for the first time since the Sergeant Maurice McCabe controversy.
Two weeks ago it emerged that a false allegation of sexual abuse was made against the garda whistleblower. The false allegation had been blamed on a clerical error.
The error was identified by a counsellor with the Child and Family Agency in 2014 and highlighted on RTÉ's Prime Time.
Speaking after the meeting in Cork, the minister said assurances were given to her that the systems were in place to ensure nothing like this could happen again.
She said the chairman, chief executive and other board members of Tusla said a reform programme was in place.
She accepted that the public's trust in the agency has suffered and that needs to be restored, adding she has ordered a Health Information and Quality Authority investigation.
Ms Zappone said: "Nothing like this can happen again".
She said the board of Tusla is clearly aware of the distress to the McCabe family.
Asked would heads roll after the investigation, she said "I don't know" but noted the CEO of Tusla has said there was no malicious intent in this particular case.
