Historical - Baseline Surveillance

• Obtaining baseline information at highest risk sites
• Providing a benchmark against which the effectiveness of border control and other management practices can be measured

• Baseline surveillance for marine pests between 2001-03 and 2005
• Baseline surveillance has been completed on non-indigenous marine species at 16 major ports and marinas of international entry
• An additional eight secondary ports and hubs have also been surveyed

Current - Targeted Surveillance

• Focusing on a specific organism or group of related organisms
• Can be designed as an on-going programme or as a one-off survey
• Maintain a watch for non-target, new-to-New Zealand organisms

• Five marine pests are currently targeted (Chinese mitten crab, European shore crab, Asian clam, Caulerpa taxifolia and northern Pacific seastar)
• Targeted surveillance programmes at 11 high risk locations, biannually, for a range of target organisms

Current - Passive Surveillance

• Asking all persons in New Zealand (including public and industry) to keep watch for unwanted pests and diseases
• Investigating notifications of suspected unwanted pests and diseases
• Monitoring and analysing trends in information relating to pests and diseases

• Targeted communication material such as lists of notifiable pests, diseases and unwanted organisms, and guides for vessel owners circulated to raise awareness and enhance passive surveillance
• The Pest and Disease Hotline (0800 80 9966)
• Incursion Investigators
