Warrick graduated in veterinary science, with distinction, from Massey University in 1985. After five years in mixed practice around the Rotorua district and a couple of years of travel interspersed with locum work, he commenced his specialty training at the University of Glasgow, Scotland. During his residency, he gained a Masters degree and a Royal College of Veterinary Surgeons (RCVS) Certificate in Small Animal Orthopaedics.
Warrick then worked as a referral surgeon in a referral veterinary hospital in London before returning to NZ in 1996 to take up a position as Lecturer in Small Animal Surgery at Massey University. He gained an RCVS Diploma in Small Animal Orthopaedics in 2000 and registered as a specialist in Small Animal Surgery (Orthopaedics).
In 2000, Warrick and his family moved to Adelaide, Australia and set up his private referral business Veterinary Specialist Orthopaedic Services. Whilst in Australia, Warrick invented the Triple Tibial Osteotomy (TTO) technique, which has become the technique of choice for many surgeons throughout the world for the management of cruciate ligament injuries in dogs. He was also employed by the University of Adelaide as Affiliate Lecturer in the Department of Orthopaedics and Trauma and was involved in their total hip replacement research.
Warrick worked in Adelaide for six years before returning home to NZ in Jan 2007 to run his business from The Pet Doctors in Hamilton.
His primary research interest has been in the investigation of post-operative motion and its effects on joint healing. He also has research interests in total hip replacement and has been involved in research projects, in collaboration with human surgeons from the Universities of Wellington and Adelaide, using both dogs and sheep as a model for human total joint replacement.
On returning to NZ, he has been actively involved in assisting the surgeons at Massey University in their total hip replacement program and was awarded Associate Senior lecturer status in 2012.
Warrick sold his business in 2018 and left the veterinary industry in March 2020, turning his hand to sailing and DIY boat building, in pursuit of a better work-life balance. In October 2020 he started part-time work as a locum at the Animal Referral Centre (ARC), Auckland. In March 2023 Warrick and his partner relocated to the beautiful Sunshine Coast and joined the North Coast Veterinary Specialist & Referral Centre Surgery Team.
Outside of work Warrick enjoys his sailing and will be making the most the most of Queensland fine weather to get out on the water.
