Eion Stevens graduated with a Diploma in Fine Arts with Honors from Otago Polytechnic in 1973.
He has exhibited since 1981 throughout New Zealand and has his work in public collections, as well as being included in New Zealand art history main reference books and periodicals.
Stevens is a consistent painter who has developed a number of images that he reuses and refines. His paintings are a curious mixture of semi-abstract forms and simply rendered figures and objects. Figurative elements are painted down to strong silhouettes. The abstract look comes from clearly defined areas of unmodulated colour which serve as sky, sea, land, walls, floors and so forth.
Stevens' paintings have a serious contemplative mood letting the viewer decipher or not decipher the work for themselves. His original approach was related to pop art.
There have been gradual changes in his work most specifically in relation to colour. Since 1985 Stevens has also been changing his rendering of forms using two styles, one surreal and childlike and the other schematic. His latter work has become brighter and purer.
