The chief executive of Queensland Health's eHealth division has been reinstated to his position after four months on the sidelines following an investigation into allegations of nepotism within the department.

A spokesperson for Queensland Health confirmed that Colin McCririck is back at work at eHealth Queensland but referred all queries about the investigation that led to him being stood aside after just three weeks in the position to the state's Crime and Corruption Commission (CCC).

Mr McCririck was stood aside on New Year's Eve along with Queensland Health deputy director-general of corporate services Susan Middleditch after allegations were made following an internal complaint regarding recruitment processes.
