Mr Corbett says he is unable to continue his consultancy arrangement with Woolworths as a result of the major expansion of Mayne Pharma, of which he is Chairman.
The announcement this week comes just seven months after he rejoined the company he once led.
“I have enjoyed the opportunity to support Woolworths with the initial stages of its transformation, and to assist the team through recent leadership transitions,” Mr Corbett said. “Given the significant changes to my other responsibilities announced today, it seems an appropriate time to withdraw. I wish Woolworths well in its future endeavours.”
Mr Corbett’s arrangement with Woolworths will now conclude at the end of July.
Woolworths Chairman Gordon Cairns thanked Mr Corbett on behalf of the Woolworths Board.
“I want to thank Roger for his advice and support over the past seven months,” he said. “Roger has assisted me since I became Chairman and has provided the benefit of his vast experience and passion for Woolworths.”
