Researchers from Te Herenga Waka—Victoria University of Wellington have shown continued loss of ice and snow in NIWA's annual end-of-summer survey. The 2023 survey was the 46th undertaken in a collaboration between the University, NIWA, and the Department of Conservation Te Papa Atawhai. The long-standing project captures an aerial portrait of more than 50 Southern Alps glaciers at a similar time each year to track how they change.
