Michael Charles Wintringham CNZM (born 1947) is a New Zealand public servant.
Wintringham was born in Blenheim, went to St John's College, Hastings,[2] and has a BA (Hons) degree from Victoria University of Wellington.
Wintringham was appointed chief executive of the Ministry of Housing by State Services Commissioner Don Hunn.
In 2001, Wintringham was sued in the Employment Court for NZ$1.2 million by former Work and Income New Zealand chief executive Christine Rankin.
Rankin lost the court case, but some of the evidence given during the hearing by Wintringham and Department of the Prime Minister and Cabinet chief executive Mark Prebble was embarrassing to all involved, and was the dominant political news topic of the year.
