The distribution, abundance and size of pipis and cockles were estimated at 12 beaches/harbours in Auckland, Northland, and Bay of Plenty. Cockle numbers increased at Whangateau Harbour and Ohiwa Estuary, but decreased at Grahams Beach. Three beaches with a rahui or restriction (Cockle Bay, Umupuia Beach, Whangateau Harbour) had significant increases in numbers of large cockles. The pipi population declined at Marsden Bank, but increased at Raglan Harbour, Whangateau Harbour and Ohiwa Estuary.
