CooperAitken, as it is today, is the result of growth and mergers over 100 years
starting in 1914 with Thomas Ryan, who was an auditor and accountant for Tatua dairy company.
Bob Aitken came to Morrinsville and joined forces with Thomas Ryan and started Ryan & Aitken. The firm originally worked out of the offices above the business that is now Sportsworld (Corner of Thames and Studholme).
Thomas Ryan passed away in 1959, and Bob Aitken ran the practice alone for some years before bringing on another partner, Michael Waddell, which lasted 12 years.
In 1981, Bob’s son Rodney become a partner and the firm then become R & RM Aitken.
Bob retired in 1993 and a few years later in 1997, Imran Raza became a partner, and firm then changed to RM Aitken & Associates.
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.
On Gary Cave and Bruce Sextons retirement in 1997, Grant Eddy and Gavin Haddon become partners and the firm was then known as Bannin, Cooper & Partners Limited.
