Minhinnick was a partly qualified architect in Auckland when the cartooning bug took hold. In the mid-1920s he contributed weekly cartoons to the Wellington-based Free Lance, before becoming staff cartoonist. His apprenticeship to daily cartooning was six months on the Christchurch Sun before joining its newly-launched sister publication, the Auckland Sun in 1927. When this folded in 1930, he joined the New Zealand Herald. He officially retired in 1976, but his cartoons appeared regularly for more than another decade. He was knighted in 1976 for his contribution to the cartoonist’s craft.
