Abstract A 790 mm fork length (FL) (6.91 kg)
kahawai netted in Waitangi Estuary, Hawke Bay, New Zealand, in August 1997 is
positively identified as
Arripis trutta (Bloch & Schneider 1801)
using meristic and morphometric characters. This fish is considerably larger
than the accepted maximum length for the species from New Zealand, and was aged
between 15
+ and 17 years. New Zealand
A. trutta of this age
are normally 460-610 mm FL. Captures of kahawai greater than 640 mm
FL and 4.0 kg in weight from New Zealand are reviewed, and a 10.0 kg
A. trutta is tentatively identified from Northland. It is suggested that
these
fish may straggle to New Zealand from eastern Australia, Norfolk
Island, Lord Howe Island, or Kermadec Islands.
