Formerly a veterinarian, Dr Walker retrained in human medicine and qualified from Auckland in 2007. He started work as a House Officer at Waikato hospital and commenced internal medicine training there before moving to Palmerston North and Wellington to complete his Fellowship in nephrology (Fellow of the Royal Australasian College of Physicians) in 2015.
During his time as a resident doctor, he was President of the New Zealand Resident Doctors Association (NZRDA) for 5 years, and currently serves on the board of the Māori Medical Practitioners Association (Te ORA). These roles reflect the strong commitment that Dr Walker has to improving health outcomes for Māori and to supporting doctors during the long and challenging years spent in specialist training.
