Abstract: Over two years monthly monitoring, four mysid species were collected. Tenagomysis chiltoni and T. novaezealandiae were the most common species. Gastrosaccus australis and T. macropsis were rarely recorded. Tenagomysis novaezealandiae was the geographically widespread species, occurs in all sites, abundant in east coast. Tenagomysis chiltoni was most abundant in west coast. Seasonal patterns in abundance of T. novaezealandiae were less apparent and it differs among sites, it may be attributed to the site-specific factors.
