Snapper (Pagrus auratus) catch-at-age data sampled from the SNA 2 bottom trawl fishery in 2007–08 and 2008–09 were investigated for spatial differences in size and age. Comparison of the differences in length and age structure, year class strength, growth, and genetics (not this study) suggest that snapper north and south of Mahia Peninsula, represent distinct substocks, if not, separate biological stocks.
