For artist and designer Vojiniaina art "has always been something very intimate, something that sticks to the skin". As an inter-disciplinary artist, Vonjiniaina's practice includes painting, sculpture, performance and installation. Working across multiple disciplines, Vonjiniaina believes, challenges her creatively as an artist. In her paintings, Vonjiniaina prefers to use washes rather than solid colour to create tones and depths.
In 2002, Vonjiniaina was invited to participate in Dak'Art and the following year she was one of the guest artists at the exhibition Latitude in Paris, France. In 2007, Vonjiniaina won the gold medal award in sculpture at the Francophone Games.
