#regional: Thank you Matua! Phil Karaitiana Retires After 56 Years of Service

After more than five decades dedicated to protecting Aotearoa’s environment and communities, distinguished biosecurity leader Phil Karaitiana has retired, marking the end of a 56-year career in the field.

Karaitiana’s work has spanned a period of enormous change in New Zealand’s approach to pest and disease management, from early hands-on field control to today’s integrated strategies that combine science, technology and community engagement. His leadership was recognised nationally when he received the Minister’s Biosecurity Award at the New Zealand Biosecurity Awards, an honour given to individuals who have demonstrated continuous and outstanding service to biosecurity.

Over the decades, Karaitiana built strong working relationships across councils, iwi, hapū, landowners and volunteers, contributing to the development of practical pest management programmes that strengthened regional and national resilience. His efforts were particularly noted in the Wairoa and Gisborne regions, where he spent much of his career leading local biosecurity initiatives.

The evolution of his work mirrored changes within the sector itself – from traditional pest control methods to the adoption of modern tools and technologies, including drones and data-driven approaches to surveillance and response. Colleagues describe Karaitiana as a mentor and champion of collaboration, with a personal dedication to protecting New Zealand’s unique biodiversity.

As he steps away from formal duties, Karaitiana leaves behind a legacy of strengthened biosecurity practice and professional capacity within regional councils and community groups. His retirement marks a milestone in an era of environmental stewardship where local leadership made a lasting impact on national biosecurity outcomes.

Radio Waatea acknowledges his lifetime of service and the contribution he has made to safeguarding Aotearoa’s environment and communities.
