After extensive travels in Europe, Africa and the South Pacific, the young Duhamel settled in New Zealand in 1987 and became a citizen in 1992. He now lives and works on Waiheke Island near Auckland from where he has spent the last 9 years establishing a bronze sculpture practice and a network of art galleries representing his work in New Zealand, in Australia and in Europe.

Priding himself on the quality of his workmanship, Duhamel casts his bronzes himself in his home foundry. This allows him to keep full control over the entire creative process.
He has been a student of David Reid (bronze casting) and Chrystle Legardinier (etching on copper plate). He has worked on contract for the studio of American sculptor Jeff Koons, NYC Since becoming a full time artist in 2006, Olivier also teaches practical creative workshops, publishes a number of popular art manuals, offers pencil drawings and lifecasting services on commission and runs a life drawing class.
