A review of Tasmania Police's handling of abuse allegations brought to them against nurse James Griffin has resulted in disciplinary action against three officers.
A professional standards investigation was launched after a review found police took a decade to formally investigate multiple reports to them about Mr Griffin.
The alleged paedophile took his own life in 2019 after being charged with multiple sex offences.

Police Minister Jacquie Petrusma in Parliament on Wednesday confirmed one police officer had been reprimanded, another counselled, and the third officer was receiving ongoing professional development as a result of the professional standards investigation.
Greens justice spokeswoman Rosalie Woodruff in Parliament on Wednesday said it appeared victims and witnesses of sexual abuse had not been taken seriously.
She asked Ms Petrusma what was being done to improve responses to such reports.
"Survivors of sexual abuse need to be reassured that they will be listened to and believed when they come forward," Dr Woodruff said.
Ms Petrusma said Tasmania Police was implementing recommendations from the review of the Griffin case released earlier this year.
She said recommendations included protocols between police and the Justice Department for Working with Vulnerable Children checks, and development of guidelines around initial investigation and notification of child sexual abuse.

Ms Petrusma said the memorandum of understanding between Child and Family Services and Tasmania Police had been reviewed to ensure appropriate responses and action was undertaken when when either party received information about child sexual abuse.
She said a full review of the Griffin matter had been provided to the Commission of Inquiry.
"As it contains highly sensitive and identifying information about victims, Tasmania Police and the other agencies are not waiting until the outcomes of the Commission of Inquiry to address the issues that can be addressed now," Ms Petrusma said.

Police Association of Tasmania president Colin Riley said he had been following news of the review.
"What is of interest to the police association is did the investigation look into the adequacy of staffing levels, the IT systems, and whether the workload was unreasonably onerous?" he said.
"If this wasn't, it needs to be looked at and any shortcomings addressed, if not already."
