New Zealand born Marietta is based in Auckland, she has painted for twenty five years in both New Zealand and Australia. For a time Marietta opened a studio in the Waikato where she gave lessons in the making of ceramics. However the lure of painting proved to be too strong, and today most of her time is spent teaching and working on her latest pieces. She is also writing and illustrating a series of children's books to be published in the United States.

Equally proficient in both watercolour and oil, Marietta's preferred choice of subject matter is still life. These striking, well-executed works successfully marry familiar objects with forms of flora or fauna. The finished works possess a quality of timelessness, with the large scale canvases being particularly well received. A pupil of acclaimed New Zealand artist Paul Coney, Marietta's latest work draws upon many techniques refined by Coney. A well-taught mastery of the transparent application of acrylic and oil is evident in her work. Each composition embraces the most striking aspects of colour, light and textural elements present in the chosen subject. This current series visually references New Zealand as a land of natural abundance. Marietta's work is a contemporary take on the great art of still life painting; clarity and freshness being uppermost in her mind.
