Our Team

A General Practitioner with special interest and training in occupational and aviation medicine, including travel medicine, he has also worked for various local companies and ACC. He has a keen interest in all aspects of general practice, particularly minor surgery and women’s health; in this latter role he worked with Family Planning for some years. He is actively involved in aviation, climbing and the running of the local gym. Somewhat unusually, he has also worked as a blacksmith for a number of years.

Dr Steven Fish

Steven Fish moved here from England in 2008 and practises four days a week. His wife, Hazel and three boys are well settled to life in Waimate and between sword fighting, cycling and Scottish dancing it is no wonder the family are now very much part of the town community.

In 2018 Steve and seven others cycled the Tour de France for the Mental Health Foundation NZ – a challenge and an achievement we are proud to acknowledge. Steve is passionate about all aspects of rural practice and particularly mental health.

Barney & Marion Clayton - Business Owners

Barney and Marion Clayton have been well known in Waimate for many years, farming and raising a family at McCulloch’s Bridge before moving to Studholme in 1997. The opportunity to take on a medical practice ensuring its success into the future was too good to miss and Oak House Medical Centre 2008 Ltd came into being. With the emphasis on service, profits are largely returned to the practice so that we are able to employ three General Practitioners, three to four Registered Nurses and a support staff including a Practice Manager and Receptionists. Being non-clinical owners comes with its challenges but it has the advantage of separating clinical and business matters so our doctors and nurses can put you first.
