A former chairman of Amnesty International UK, Dr Oestreicher is Canon Emeritus of Coventry Cathedral and a retired director of its Centre for International Reconciliation.
He now lives in Brighton, England, with his wife, Prof Barbara Einhorn, who has an Otago University doctorate in German.
The university will confer an honorary doctor of divinity degree on him at the third of its graduation ceremonies, on Saturday, May 23.
The university will hold 10 graduation ceremonies this year.
Dr Oestreicher, who has spent much of his life in England, will also give the graduation address.
University vice-chancellor Prof David Skegg said Dr Oestreicher had devoted his life to working for peace and social justice through his preaching, writings and work with the church and other international organisations.
He had also applied Christian principles such as reconciliation and forgiveness, Prof Skegg said.
As a child, he and his Jewish-born father and non-Jewish mother spent months hiding from Nazi authorities in Berlin before gaining asylum in New Zealand.
After moving to Dunedin at the age of 7 in 1939, he attended Kings High School (1945-49).
In 1953, he gained a BA in political science and German in 1953 at Otago University, where he was active in the Student Christian Movement and became an Anglican.
He subsequently also studied at the University of Bonn, West Germany.
