At the 2024 National Wetland Trust Symposium held in Paihia, a new revised method to map the pre-human wetland extent layer for Aotearoa New Zealand (AoNZ) was presented by Dr Olivia Burge to approximately 190 attendees including staff from regional councils, iwi groups, central government including the Department of Conservation, industry consultants and other Crown Research Institutes. Next steps are for the method to be written up fully as a set of case studies, before seeking funding to roll it out nationally.
