Toheroa and tuatua are two species of infaunal surf clam endemic to New Zealand. This report documents the findings of two intertidal survey projects, conducted to determine the distribution, abundance and size structure of toheroa and tuatua populations in Northland at Ninety Mile Beach in 2010 and Dargaville Beach in 2011. Each survey used a 2-phase stratified random sampling design. Patterns in spatial distribution along the beach and down the shore were described, together with trends in the 1933–2011 time series of toheroa abundance estimates for these beaches.
