New requirements for general transitional facilities The new General Transitional Facilities for Uncleared Goods standard, which replaces several older standards, came into effect on 1 February this year. Finalising the standard was a significant piece of work for the MAF Biosecurity New Zealand (MAFBNZ) Operations and Facilities Group. The standard underwent two rounds of public consultation, as well as extensive internal consultation, to ensure a smooth transition from old to new. To communicate the changes to the more than 6000 transitional facilities across New Zealand, a series of public information sessions was held in major centres in early December last year. These sessions New Zealand’s plantation forests are worth billions of dollars, but were led by MAFBNZ Group Manager, Operations and as with dropping a match and starting a forest fi re, the accidental Facilities, Clive Gower-Collins and Team Manager, Operations and Facilities, Tania Marinas, and introduction of a dangerous pest organism can be devastating. provided information about how businesses would o reduce the risk of new such as pocket knives, pruners and be affected. damaging insects and fungi even cameras and binoculars.

It is a notifiable and unwanted organism under the Biosecurity Act 1993. Fanworm Response Manager Dr Peter Stratford says the fanworm can have significant negative effects, being an invasive species with no known predators and an ability to thrive in a wide range of habitats. “The fanworm could displace existing native species, threaten high value conservation and biodiversity areas, and foul port structures, vessels and aquaculture farms. This pest generally thrives in sheltered bays and harbours where it is likely to successfully compete with scallops, oysters and mussels, amongst other species, for food and space. It may also alter the fish species present in an area. “It is important that we carry out these measures to try to rid the Lyttelton Port of this pest and prevent its spread to other high value areas such as the wider Divers working on initial surveying for the fanworm.

Pest watch: 15/11/2008 – 19/12/2008 Biosecurity is about managing risks – protecting the New Zealand environment and economy from exotic pests and diseases. MAF Biosecurity New Zealand devotes much of its time to ensuring that new organism records come to its attention, to follow up as appropriate. The tables here list new organisms that have become established, new hosts for existing pests and extensions to distribution of existing pests. The information was collated between 15 November and 19 December 2008. The plant information is held in the Plant Pest Information Network (PPIN) database. Wherever possible, common names have been included.
