An acoustic survey to determine the abundance of smooth oreo in area OEO 4 was carried out between 8 and 26 November 2012 using Tangaroa (TAN1214) for acoustic work and San Waitaki (SWA1201) for trawling. Previous acoustic surveys were carried out in 1998, 2001, 2005, and 2009. The total estimated abundance of smooth oreo for OEO 4 was 88 600 t with a coefficient of variation (CV) of 42%. About 18% of the total estimate came from one school mark on the flat which was not fished.
