Study encompassesall major beaches and cockle habitats, but excludes offshore sand banks. Generally thereis an increase in abundance from high to low tide. Low abundances were found at DuckCreek, Ration Point, Kakaho and Cainborne. Numbers were high at Browns Bay,BTOmley and Pauatahanui. Compared with previous study, cockle numbers havedecreased by around 50%.

Total population estimated 10have declined from 438-608 million individuals in 1976, to 187-257 million in 1992 andto 146-214 million in 1995, representing slightly more than one third of the 1976population. The 1995 survey recorded a slightly greater abundance of juvenilescompared with the 1992 survey possibly indicating a recoveryGrange, K. R. and T. Crocker (1999).
