Dr Ollie Lee (Chiropractor) B.Chiro NZCA
Dr Ollie Lee grew up in the northern suburbs of Wellington and graduated from the New Zealand College of Chiropractic in Auckland.
Ollie has always been exposed to chiropractic, as his mother started seeing one to help with back pain from carrying him as a baby. She discovered how chiropractic was not only useful for pain, but helped her navigate all aspects of daily living- leading to both of Ollie’s parents having been under regular care his whole life.
Ollie has experienced first-hand how chiropractic can help people get the most out of their life and excel at the things they do and love. He is passionate about human health, performance and the incredible ability of the body to adapt and change so people can reach their goals.
Outside of chiropractic, you can find Ollie lifting weights, running, enjoying some weekend basketball and trying to find the next best thing to eat in town. He is also keen into music, and is the 3x national New Zealand Beatbox champion. In 2026 Ollie also ran his first marathon in Taupo.
Ollie is thrilled for the opportunity to be part of the Kapiti community and is dedicated to supporting you in all of your health goals- big or small!
