In 2008, a preliminary assessment was carried out for the Bounty Platform stock. New abundance data were available from an industry acoustic survey of the Bounty Platform that indicated that there has been a very large increase in biomass in this stock since 2004. An attempt was made to fit this timeseries of industry acoustic data, along with a time series of Tangaroa acoustic surveys and catch-atage data, in a population model. Because of the poor fit to the acoustic data the model results are not reported here, but the Working Group did provide conservative estimates of biomass (section 4d) based only on the acoustic survey results to allow yield estimates (CAY) to be determined for the management of the fishery.
No new assessments are available for the Campbell Island and Pukaki Rise stocks. No assessment has been made of the Auckland Islands Shelf stock. The years given in this section of the report refer to the August-September spawning/fishing season.

The 2007 stock assessment was not updated. For the base case, B2006 was estimated to be 78 000 t (90% credible interval 56,000–106,000 t), corresponding to 30%B0 (90% credible interval 20–41%).
The catch is dominated numerically by the strong 2001 and 2002 year classes, and the incoming 2004 year class also appears to be above average. The TACC was reduced to 20,000 t in 1 April 2006, and at this level of catch, th
