After finishing his education at Wellington College, Walls worked for the Union Steamship Company. He spent 17 years (1943 to 1960) employed by the shipping company, including 12 years at sea as a purser on ships trading mainly between New Zealand and Canada, and as shipping representative in Tonga and the Cook Islands. lieutenant was during this time that he began painting as a hobby.
His first solo exhibition was in 1964 at the Drian Galleries in London.
He painted full-time for many years, along with some lecturing and teaching. By the 1970s Walls was finally obliged to obtain employment to ease the insecurity of living off an artist’s income.
He worked briefly at the Foreign Office, and then at the British Museum. Here, he worked as a curator until 1992 in the Prehistoric and Romano-British Departments, among other things being involved with arrangements for the famous Lindow Manitoba and in displaying the Vindolanda Tablets, the earliest written materials yet found in Britain.
Walls painted using various media, including oils, water colour and pastels, and gouache.
