Clean Green New Zealand Confronts Forever Chemicals
New Zealand—internationally marketed as “clean and green”—has been confronting the reality of PFAS contamination since 2016, when investigations at military bases and airports revealed significant groundwater contamination from AFFF use. The New Zealand government’s response—systematic site investigation, community health assessments, interim water supply measures, and the development of a national remediation framework—has evolved into one of the more comprehensive national PFAS response programs in the Southern Hemisphere, providing lessons applicable to other countries addressing similar contamination profiles.
Military Base Contamination: Ohakea and Beyond
Royal New Zealand Air Force Base Ohakea in the Manawatu region was the first major New Zealand PFAS contamination site to receive sustained public attention. AFFF use in fire training exercises and emergency response over several decades produced a significant groundwater PFAS plume extending beyond the base boundary to affect private properties and community wells. The New Zealand Defence Force (NZDF) commissioned comprehensive investigations and implemented interim water supply measures—including provision of bottled water and connection of affected properties to mains water supply—while longer-term remediation planning proceeded.
RNZAF Base Woodbourne in Marlborough, Base Wigram in Canterbury, and RNZN Devonport in Auckland have all been investigated for PFAS contamination associated with AFFF use, revealing a pattern of military PFAS contamination that mirrors findings at similar installations globally. The NZDF established a dedicated PFAS team and committed to transparent community communication and comprehensive remediation—a governance approach that earned qualified community trust even when remediation progress was slow.
Civilian Airports and Fire Training Facilities
Auckland, Wellington, Christchurch, and Queenstown international airports—as well as numerous regional airports—have used AFFF in fire training programs required under Civil Aviation Authority regulations, producing PFAS groundwater contamination at multiple sites. New Zealand’s Civil Aviation Authority and Airport Authority New Zealand have coordinated PFAS investigation programs that are characterizing contamination extent and informing remediation planning. The airports’ PFAS contamination intersects with sensitive receiving environments: Auckland Airport sits adjacent to the Manukau Harbour, an important ecological area and customary fishing ground for Māori communities with treaty-protected interests in the resource.
New Zealand’s transition from AFFF to fluorine-free foam alternatives has been accelerated by the combination of environmental contamination evidence and regulatory pressure. The Civil Aviation Authority has updated its requirements to accommodate F3 foams at civilian airports, with major airports completing the transition to fluorine-free fire suppression systems. The NZDF is on a phased transition timeline for military AFFF replacement, balancing operational requirements with environmental protection imperatives.
Health Assessment and Drinking Water Standards
New Zealand’s Ministry of Health has implemented drinking water quality standards for PFAS through the New Zealand Drinking-Water Standards, setting maximum acceptable values for PFOS, PFOA, and combined PFAS that align broadly with international guidance while reflecting New Zealand’s specific regulatory framework. Community health assessments conducted near contaminated sites have provided biomonitoring data—blood PFAS testing for residents with potential contaminated water exposure—that has informed risk communication and health monitoring programs. New Zealand’s experience demonstrates that timely, comprehensive health assessment programs—even when they reveal concerning exposure levels—are essential for maintaining community trust and providing the health information that affected individuals need to make informed decisions.
