In 1986 he was appointed Department of the Prime Minister and Cabinet Secretary.[6] In 1987 he worked with Prime Minister Bob Hawke to introduce massive reform changes to the public service, creating "super ministry" departments.[7] Codd did note potential disadvantages of the machinery of government changes, including that there was potential for "bunker mentality" to continue.[8]
Codd retired from the public service in December 1991,[9] his appointment was terminated by an Executive Council meeting on 27 December that year.[10]
After his retirement from the Department of the Prime Minister and Cabinet, Codd joined consultancy firm Coopers and Lybrand.[11] He was also appointed to the board of Qantas in 1992, prior to the airline's privatization, and served 16 years retiring in 2008.[12] Between 1997 and 2009 he was Chancellor of the University of Wollongong (UOW), retiring in September 2009.[13]
In 2009, the University of Wollongong awarded Mike Codd an honorary degree and in 2010 named a building after him on its Innovation Campus in recognition of his eminent service as the university's second Chancellor. His portrait (by Mathew Lynn, 2014) hangs in the Codd building.[citation needed]
