Résumé :	Berm breaching of intermittently closed estuaries, either naturally or due to management practices, results in a physicochemical disturbance due to the flushing of water, material and biota into the ocean and the subsequent tidal influx. In 2007 and 2008 comparative and controlled studies were employed in three New Zealand estuaries: Sawmill Creek (46 degrees 04'S 170 degrees 12'E), Otokia Creek (45 degrees 57'S 179 degrees 20'E) and Kaikorai Lagoon (45 degrees 56'S 170 degrees 23'E), to investigate the impact of berm breaching on the hyperbenthic macroinvertebrate community in intermittently closed estuaries. Significant changes in community structure occurred in both the weekly comparative and the controlled studies (ANOSIM P
