Abstract
TRE 1
The assessment for TRE 1 undertaken in 2006 was not accepted by the Pelagic Working Group due to the lack of a reliable abundance index. Recent catches reported for TRE 1 are less than the estimated MCY levels and below the TACC. Reduced proportions of older age classes in the single bottom trawl catch between 1999-00 and 2006-07 combined with the strong drops in landings in 2006-07 and 2007-08 may indicate that stock abundance is declining at current catch levels.

TRE 2
From 2002-03 to 2006-07 reported catches for TRE 2 were substantially larger (average 325t) than the TACC (241t) but fell to the level of the TACC in 2007-08. It is not known if these recent catches are sustainable.

TRE 7
Stock Structure Assumptions
Trevally occurring along the west coast of the North Island are believed to comprise a single stock.
