A one-year sabbatical in rural hospital medicine and primary health care became eight years based in Reefton on the West Coast, with occasional postings to the Chatham Islands. This was followed by four years at a remote rural hospital and general practice in Western Australia, working as a solo ‘bush doctor’ for a small mining town and two Aboriginal communities.



Buzz went on to establish a semi-rural general practice in Renwick, near Blenheim. He was the GP with a special interest in chronic pain for the Nelson region, and served as regional coordinator and senior lecturer for the University of Otago Rural Medical Immersion Programme before relocating to Auckland full-time in 2020.


He is an examiner for the Royal New Zealand College of General Practitioners, has served a term as Chair of the College Rural Chapter, and is currently Interim Chair of General Practitioners Aotearoa.


Buzz has completed training as a pain medicine specialist in Auckland and now works part-time as a Senior Medical Officer for the Auckland Regional Pain Service. He has published on asthma, COPD, and a range of primary care topics, and has advised the Ministry of Health through various committees over the years.


His diverse experience drives him to be thorough and evidence-based in his approach, supported by a trusted network of senior colleagues to help provide patients with the most comprehensive and up-to-date care possible.


Outside of work, Buzz is the proud father of three daughters, a very slow ocean swimmer, a Harley rider, and recently completed his first half-marathon. He’s also been known to enjoy a glass of Shiraz with friends.

Dr Burrell (Buzz) leads the Pain Clinic at Parkview Medical Group, where he works exclusively as a pain specialist.

He graduated from St George's Hospital Medical School in London in 1986 before completing his specialist general physician training in Derbyshire. He then emigrated to New Zealand as a respiratory research fellow and lecturer for the University of Otago. Buzz was voted Lecturer of the Year in Dunedin 1993 and Runner up New Zealander of the Year in 1997.
