Kia ora,

On behalf of the Council of Australasian Weed Societies, the New Zealand Biosecurity Institute (NZBI), and the New Zealand Plant Protection Society (NZPPS), we are delighted to invite you to the 24th Australasian Weeds Conference (AWC), to be held in Ōtautahi Christchurch, Aotearoa New Zealand, from 23–27 August 2026. This cross-Tasman conference is a cornerstone event for everyone involved in weed research, biosecurity, land management, and policy across Australia, New Zealand, and the Pacific Islands. The AWC provides an essential opportunity to share knowledge, discuss the latest innovations, and build strong professional networks dedicated to tackling the challenges of weed management. Much has changed since the last AWC in New Zealand in 2010 – new incursions, evolving management strategies, and emerging technologies. However, one thing remains constant: our commitment to collaboration, learning, and face-to-face connection. Our 2026 conference theme _Collaboration Across Borders: Sharing knowledge for effective weed management_ reflects the importance of working together across regions and disciplines to protect our unique environments, economies, and communities from the impacts of invasive weeds. This year’s conference will be extra special as it will also incorporate the New Zealand Biosecurity Institute’s annual National Education and Training Seminar (NETS) bringing together two highly respected events under one roof for the first time. This integrated programme will bring together professionals working across weeds, pathogens, vertebrate, invertebrate, aquatic, and marine pest management creating a rare opportunity to connect disciplines and strengthen collaboration across the wider biosecurity system. Whether you are a delegate, a sponsor, or a presenter, there are many ways to be involved: - Attend to gain insights and share your expertise with a passionate and engaged community. - Sponsor an event, session, or programme element to demonstrate your support and connect with sector leaders. - Submit your abstract for inclusion in this groundbreaking programme We are excited to host this important event in our vibrant and resilient city and look forward to welcoming you to Te Pae Christchurch Convention Centre – a world-class venue set in the heart of the South Island.
