The report presents a CPUE analysis for the three component SNA 1 substocks: East Northland, Bay of Plenty, Hauraki Gulf and spans 21 fishing years (1989–90 to 2009–10).  The longline CPUE indices for the Hauraki Gulf and the Bay of Plenty show similar generally increasing trends over the 21 year series. The Bay of Plenty trawl CPUE index also had a generally increasing trend over most of the series, but decreased in the final two years. The East Northland longline CPUE index fluctuated over the 21 year series; the final year (2009–10) had the same value as the starting index year (1989–90).
