As well as conducting general optometric services such as eye examinations, visual screening and children's vision, Kerry specialises in Keratoconus, complex contact lens fitting and management; often taking referrals from colleagues and eye surgeons.


Kerry holds a Degree in Optometry (Honours) from City University in London and a specialist qualification in Contact Lens Practice. Kerry is also a Fellow of the British College of Optometrists and a Certified Examiner  for the New Zealand Police.


Kerry worked as a contact lens practitioner in the UK before returning to New Zealand, where he began teaching at The University of Auckland Department of Optometry and Vision Science. As the optometry course developed, teaching of contact lenses became a separate entity. Kerry further developed the course, and with the help of others (notably Grant Watters), went on to lecture, teach and examine undergraduate optometrists in the specialised area of contact lens practice.


Kerry also continued to work in Otahuhu, Birkenhead and Mairangi Bay, establishing a reputation for excellence in optometry and specialised care of contact lens patients, particularly those wearing rigid lenses and those with Keratoconus. Kerry still works part-time at The University of Auckland as a Professional Teaching Fellow, teaching clinical skills and conducting a specialist contact lens clinic for final-year students.


Kerry has taught and lectured on Contact Lenses globally and was a member of the International Association of Contact Lens Educators. Kerry was invited to Hong Kong Polytechnic University to lecture on ‘Updates on Contact Lens Complications and Patient Management’ and was employed as an educator for Allergan, travelling across New Zealand presenting to groups of practitioners about the problems of treating dry eyes. Kerry has also spoken to members of the New Zealand Contact Lens Society on impression materials in contact lens practice.


Kerry was asked to contribute to world-renowned textbook Contact Lenses edited by Phillips and Speedwell. He has enjoyed time as the Vice President and President of the New Zealand College of Optometrists and has helped facilitate conferences for the New Zealand Contact Lens Society.


Throughout his career Kerry has continued his education, completing a Bachelor of Science (BSc) and a qualification in ocular therapeutics. The ocular therapeutics qualification enables Kerry to prescribe therapeutic medication for superficial eye infections, inflammations and allergies.


Kerry’s addition to the clinical team further enhances the specialty skills, knowledge and extensive experience that ensures Mortimer Hirst remains a leading New Zealand independent practice.
