Shane Christie's CTE Diagnosis: Advocating for Player Welfare in Rugby
Shane Christie, a former Māori All Black and Highlander, was diagnosed with a brain disease likely linked to repeated head injuries by a pathologist at the University of Auckland's brain bank. Before his death at the age of 39 in August 2025, Christie was found to have a high stage of chronic traumatic encephalopathy (CTE). This diagnosis was confirmed by a second pathologist who noted that Christie had suffered several significant concussions during his playing career. Christie had retired from professional rugby in 2017 due to severe post-concussion symptoms and had publicly expressed his belief that he was suffering from CTE, a condition associated with repeated head trauma. His brain was donated to the University of Auckland's brain bank and examined posthumously, confirming the CTE diagnosis.
Following Christie's death, New Zealand Rugby expressed condolences to his family, friends, and former teammates. The organization acknowledged the CTE pathology results and emphasized the importance of supporting players with post-concussive symptoms. New Zealand Rugby recognized the association between repeated head impacts and CTE, highlighting the need for ongoing research in this area. The organization emphasized its commitment to player safety at all levels of the game, implementing measures such as Head Injury Assessments, recovery periods, and brain health services. While research on the long-term effects of head injuries continues, New Zealand Rugby remains focused on providing support to the rugby community.
Christie's former teammate and close friend Billy Guyton, who died in 2023, was the first New Zealand-based professional rugby player diagnosed with CTE. Christie co-founded the Billy Guyton Foundation to raise awareness about brain injuries in rugby and advocate for increased duty of care in the sport. He shared his struggles with concussion symptoms and fears of having CTE through social media posts. Christie's partner, Holly Parkes, revealed that she had known about his CTE diagnosis in 2023 and emphasized the importance of recognizing the physical impact of brain injuries, not just psychological issues. Parkes criticized the lack of acknowledgment and support from New Zealand Rugby and the Players Association regarding the link between head trauma and CTE.
Parkes continued Christie's advocacy work after his death, promoting better access to support and treatment for individuals dealing with head injuries from contact sports. She established KnockStop to provide early intervention and proper care for concussion-related issues. Parkes aimed to make concussion kits available in pharmacies nationwide and raise funds for treatment options. Craig Morice, a lawyer who worked with Christie, highlighted the significance of the CTE diagnosis in understanding Christie's struggles and advocating for player welfare in rugby. Morice emphasized the need for New Zealand Rugby to address concussion management and make the game safer for players of all ages.
The CTE diagnosis of Shane Christie sheds light on the long-term effects of head injuries in rugby and underscores the importance of player welfare and safety in the sport. As the rugby community grapples with the implications of repeated head trauma, efforts to support players with post-concussive symptoms and raise awareness about brain injuries remain crucial. Christie's legacy serves as a reminder of the challenges faced by athletes dealing with the consequences of head injuries and the ongoing need for research and support in the rugby community.
