Born in Harare, Zimbabwe, Portia Zvavahera studied at the Harare Polytechnic and the National Gallery of Zimbabwe School of Visual Art and Design. Her practice gained international attention for its distinct technical approach, which involves the application of oil-based printing ink onto canvas, often combined with oil paint to create textured, ethereal surfaces.

Her work frequently centers on the human figure, drawing from personal experiences, religious iconography, and traditional Zimbabwean motifs. By layering translucent colors and gestural marks, she creates compositions that evoke emotional states and spiritual narratives, often focusing on the vulnerability and resilience of the female form.

Zvavahera has established a significant presence in the global contemporary art scene, with her work featured in major international exhibitions and institutional collections. Her paintings are recognized for their ability to bridge the gap between the physical and the metaphysical, maintaining a consistent focus on the expressive potential of paint and printmaking.
