In 1943, Stuart Shepherd (Tui) established an accounting practice in Morrinsville, founded on farm and small businesses accounting. After 40 years with the firm Tui passed away. Gary Cave and Garry Barnett took over until Brian Allison joined them in 1960’s, and the firm became Barnett, Cave & Allison.

Allison soon moved on and Alan Bannin joined the firm in 1966, becoming Barnett, Cave Bannin & Co. In 1973, Bruce Sexton facilitated another name change by becoming a partner and the firm became Barnett, Cave, Bannin, Sexton.

In 1987 Trevor Cooper’s recently purchased practice amalgamated with the firm and it became known as Cave, Bannin, Sexton, Cooper. Trevor was the first ‘local’ to join the firm and was well known by Morrinsville people.
