The Marine High Risk Site Surveillance (MHRSS) is a national programme of surveys targeted at the early detection of high risk marine non-indigenous species (NIS). The primary objective of the MHRSS programme is to detect incursions of New to New Zealand non-indigenous organisms listed on the Unwanted Organisms Register at ports and marinas throughout New Zealand previously identified as high risk for the introduction and establishment of marine NIS. The MHRSS programme also has two secondary objectives, which are: (i) to detect incursions of marine NIS or cryptogenic organisms not previously recorded in New Zealand, and; (ii) to detect range extensions by marine NIS or cryptogenic organisms that are already established in New Zealand waters. The MHRSS programme is designed to detect the presence of five primary (Asterias amurensis, Carcinus maenas, Caulerpa taxifolia, Eriocheir sinensis and Potamocorbula amurensis), and four secondary (Arcuatula senhousia, Eudistoma elongatum, Sabella spallanzanii and Styela clava) target NIS. Each High Risk Site is surveyed bi-annually (hereafter referred to as the winter and summer surveys). This Annual Synopsis Report details the targeted surveillance surveys at the 11 High Risk Sites during the periods June–September 2016 (the Winter 2016 round of surveys) and November 2016–May 2017 (the Summer 2016–17 round of surveys). The number of locations sampled generally met the overall MHRSS programme survey targets. A total of 2849 locations (98.1% of target 2903) were surveyed during the Winter 2016 surveys. A total of 2923 locations (100.7% of target 2903) were surveyed during the Summer 2016–17 surveys. No primary target species were detected, but all four secondary target species were detected at various locations and times: • Arcuatula senhousia was recorded during the following surveys: Waitemata (Winter 2016, Summer 2016–17); and Whangarei (Winter 2016, Summer 2016–17). • Eudistoma elongatum was recorded during the following surveys: Opua (Winter 2016, Summer 2016–17); and Whangarei (Winter 2016, Summer 2016–17). • Sabella spallanzanii was recorded during the following surveys: Lyttelton (Winter 2016); Nelson (Summer 2016–17); Picton (Winter 2016); Tauranga (Summer 2016–17); Waitemata (Winter 2016, Summer 2016–17); and Whangarei (Winter 2016, Summer 2016–17). • Styela clava was recorded during the following surveys: Lyttelton (Winter 2016, Summer 2016–17); Nelson (Winter 2016, Summer 2016–17); Opua (Winter 2016, Summer 2016–17); Otago (Winter 2016, Summer 2016–17); Picton (Winter 2016, Summer 2016–17); Tauranga (Winter 2016, Summer 2016–17); Waitemata (Winter 2016, Summer 2016–17); Wellington (Winter 2016); and Whangarei (Winter 2016, Summer 2016–17). The number of specimens collected and sent to the Marine Invasives Taxonomic Service (MITS) for formal identification per survey ranged from none to 12. The total numbers of specimens sent to MITS were 24 for the Winter 2016 round and 47 for the Summer 2016–17 round. Five of the 24 specimens sent to MITS from the Winter 2016 surveys were NIS, including the red alga Grateloupia turuturu (Lyttelton, and G. cf. turuturu from Nelson), the caprellid amphipod Caprella cf. penantis (Tauranga), the fish Chironemus maculosus (Port Taranaki) and the solitary ascidian Styela clava (Wellington). • The record of C. cf. penantis from Tauranga Harbour represents a New to New Zealand record • The record of C. maculosus from Port Taranaki represents a MHRSS programme range extension. Ten of the 47 specimens sent to MITS from the Summer 2016–17 surveys were NIS, including the caprellid amphipod Caprella scauroides (Waitemata), the amphipod Apocorophium acutum (Waitemata) and the colonial ascidians Botrylloides giganteum (Whangarei), Clavelina lepadiformis (Wellington), Polyandrocarpa zorritensis (Whangarei) and Symplegma brakenhielmi (Waitemata and Whangarei). • The record of C. scauroides from Waitemata Harbour represents a New to New Zealand record • The record of C. lepadiformis from Wellington Harbour represents a MHRSS programme range extension. MPI was informed of the New to New Zealand species and range extensions at the time of collection, or the time that specimen identity was confirmed.
