Introduction

Summary
Since 1993, underwater visual surveys recorded no consistent increases in snapper (Pagrus auratus) abundance and size until 2008. This change appeared to be due to the Department of Conservation (DOC) increasing compliance efforts and an alteration in sampling methodology from 2004.
