✦ Synopsis

Macrobenthic samples .were collected along 3 north-south transects at 244-1394 m depth across the Chatham Rise, eastern New Zealand, to examine the distribution of polychaete assemblages in the region of the Subtropical Convergence (STC). Two main assemblages were identified: at 244-663 m depth occurring mainly on the crest of the Rise, and at 802-1394 m on the slopes of the Rise. Community composition differed,. however, between the northern and southern slopes of the Rise. The southern slope supported higher faunal densities and a greater proportion of surface deposit feeders. This latitudinal difference may reflect variability in organic flux across the STC.
