Description: The wetland assessment considered definitions and classification from the National Policy Statement for Freshwater Management (NPS-FM) and the Wetland Types in New Zealand document (Johnson and Gerbeaux, 2004). Mapping effort was focused on identifying natural wetlands rather than artificial or improved pasture type wetlands. Wetland polygons were smoothed using the Polynomial Approximation with Exponential Kernel (PAEK) method with a smoothing tolerance of 20 m. Farm ponds smaller than 1,000 m² were not mapped, and some wetlands highly likely to fall under the pasture exclusion criteria or former wetlands were excluded. Overall, a total of 2,755 individual wetlands were delineated and classified in the Waipaoa, Waiapu, Hangaroa-Ruakituri, Uawa, Waimata, and Wharekahika-Waikura catchments.Data delivered by Morphum Environmental August 2022
