Meet Your National Executive

Dr. James Anderson
President
I’m in my fourth year as President of the NZRDA, following roles as Vice President and Southern Region Executive Representative. I’m an advanced training Paediatric registrar based in Wellington and, though originally from Scotland, I’m now proud to be a citizen of Aotearoa New Zealand. Passionate about advocating for the rights of both patients and colleagues, I believe in leaving things better for those who come after us. A strong union is essential for achieving this in healthcare, and the NZRDA provides a meaningful platform to address the power imbalance between employers and employees. I’m approachable and happy to assist with union or workplace challenges—feel free to reach out in person or via the NZRDA office.
