He collaborated with his father in sculptures for the churches of San Zanipolo at Venice and in Santa Caterina at Pisa, and provided some panels for the bell tower of Santa Maria del Fiore. Nino succeeded his father in the works of the Orvieto Cathedral in 1349.
Works he made alone include a Madonna with Child in Santa Maria Novella, Florence, a Saint Bishop in the Cathedral of Oristano and a Monument to Bishop Scherlatti now in the Museum of Pisa Cathedral. His other attributed works include a Madonna of the Rose in Santa Maria della Spina and a Madonna del Latte in the Museum of St. Matthew, both in Pisa. An Annunciation, once in Santa Caterina, is now in the National Gallery of Art in Washington, D.C..
