An investigation has revealed details of the conduct of Queensland's former electoral commissioner, Walter van der Merwe.

Attorney-General Yvette D'Ath tabled a summary in Queensland Parliament of the Crime and Corruption Commission’s (CCC) review of Mr van der Merwe's time as commissioner, which states he was drunk in the workplace, regularly absent without reasonable excuse, and seen in a compromising position “of a sexual nature” with an employee.

Mr van der Merwe stepped down in February after complaints were raised with the Attorney-General's office.

The summary found substantial evidence for five of the seven allegations against him.

The report said he also showed favouritism, told senior managers to go easy on employees who were considered to be his friends, and overruled senior managers.

“Van der Merwe routinely did not perform his functions as electoral commissioner when in the workplace,” the summary by CCC chairman Alan MacSporran said.

“An example given related to an incident where he was allegedly seen in a compromising position with a temporary employee — it is believed the conduct was of a sexual nature.”

Ms D'Ath said it is a difficult time for the Electoral Commission Queensland (ECQ).

“Those circumstances are by no means a reflection of ECQ staff more broadly,” she said.

“As a public sector agency, it is crucial that the ECQ always retains the full confidence of the Queensland public and that it reflects the highest levels of ethics and integrity in the important work that it does.

“Staff should also expect a healthy workplace culture that supports staff wellbeing.”

Ms D'Ath is seeking to appoint a new acting electoral commissioner “to provide fresh eyes and stability for the organisation while the position is being filled permanently”.

Deputy commissioner Dermott Tiernan has held the top position since Mr van der Merwe's departure.
