Outgoing Treasury Secretary Gabriel Makhlouf has apologised for not keeping Budget information secure.
It also criticised him for not taking responsibility for the incident.
In a statement this afternoon, Mr Makhlouf has apologised for not keeping the information secure.
"Mr Ombler's investigation was conducted thoroughly and fairly. I have read the report carefully and encourage others to do so. I apologise that Budget information was not kept secure."
However, he said the report confirmed he acted in good faith and without political bias.
"It also confirms that I acted reasonably, other than in my descriptions of the incident. I am pleased that my honesty and integrity are not in question."
He said a separate inquiry would look at exactly how the Budget information was accessed, and how to stop it from happening again.
