Island Invasives 2026 is the fourth conference in the Island Invasives series that started in Auckland, New Zealand in 2001. The goal of the conference is knowledge transfer that enables accelerated uptake of eradication methodologies which will enhance biodiversity and the lives of people on islands around the world. In February 2026 the conference returns to Auckland to celebrate its 25th anniversary. The conference continues its resolute focus on the complete eradication of invasive species of any taxa from islands or island-like bodies. Scholars and practitioners from around the world will convene to present on any aspect of this topic with their work published as peer-reviewed papers in the renowned conference proceeding series. Sponsors of the conference will have direct access to this global audience to promote their organisation and services.
