Ken Henry takes up job at NAB

Life just keeps getting busier for former Treasury secretary Ken Henry. As well as writing a white paper for the Gillard government on Australia's engagement with Asia, he is now a member of the National Australia Bank board.

Henry, who retired in June after 10 years as Treasury secretary but continues to work as an adviser to the Prime Minister, will be a non-executive director of the bank from November 1.

But that's not all, Henry told The Australian that he's keen to take up more board roles in the future. 

Henry and Prime Minister Julia Gillard were quick to reject any suggestions of a conflict of interest.

"I have no doubt that I will be able to discharge both sets of responsibilities effectively," Henry told The Australian. 

"This project (the Asian century) is a very, very broadly based project that goes well beyond financial services."
