Our History

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.

Aitken Story
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.

Bob retired in 1993 and a few years later in 1997, Imran Raza became a partner, and firm then changed to RM Aitken & Associates.

Cooper Story
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.
