After graduating Avis soon became the head designer for Silk and Textile Printers in Sydney, a firm famed for its avant garde approach to textiles. With her inspired and refreshing ideas Avis quickly earned a reputation as one of Australasia's most innovative textile designers.
Returning to New Zealand in 1948 Avis created a portfolio of designs featuring Australian and New Zealand motifs. It was these designs that later caught the attention of design historian Douglas Lloyd Jenkins, who curated the touring exhibition Avis Higgs: Joie de Vivre in 2000. Her extraordinary talent as a textile designer is now preserved at the Hawke’s Bay Museum and Art Gallery.
Throughout the 1950s and 60s Avis was an active member of the New Zealand Academy of Fine Art, the Architectural Centre Gallery and the Helen Hitchings Gallery. She was a foundation member of the Wellington Society of Watercolour Artists where she became president.
Exhibiting widely throughout New Zealand, Avis won numerous awards including the National Bank award for watercolour in 1964 and the IBM New Zealand Academy of Fine Arts Award for Townscape in 1985. In 2006 Avis was awarded the Governor-General’s Art Award for her contribution to New Zealand art, and held a retrospective of her work at the Academy of Fine Arts.
With the renewed interest in Avis’ textile work, Dilana Rugs reproduced six of her designs for an exclusive collection and Laurie Foon of Starfish reproduced a limited edition of Avis’ duckpond design for her 2006/7 season.
