Leading Waikato
Accounting Firm since

Making a positive difference for over 70 years.
Our Story
Osbornes Chartered Accountants (OCA) was established in 1946 by John Osborne who was a returned serviceman. The practice has continued to grow over the decades with some families being fourth generation clients.
Initially Osbornes serviced the local business community, with no farming clients, but we now service a large and diverse customer base ranging from plumbers to kiwifruit growers, passive investors to large corporate farmers.
Technology has been extremely important over the years for the firm, leading the way and adopting the best technological advances - most recently moving the practice to a cloud based system.
