She was born in 1973 in Blantyre, Malawi, and graduated in Fine Arts from Rhodes University, South Africa. Her mother worked in the textiles industry on sewing and embroidery. In her artistic training, she tested several modes of expression, but finally became passionate about the work of silk, both because of the interest in the fabrics, the luminosity and the effects of reflection of it. She indicated that: “Silk has a fabulous quality of reflection but at the same time, I think it is very modern and at the forefront of fashion”. In 2018 Zangewa was the featured artist for the annual FNB JoburgArtFair. In 2019 Zangewa was included in the show I Am… Contemporary Women Artists of Africa at the National Museum of African Art.
