Frequently Asked Questions

Could didymo spread to lakes throughout New Zealand?

Yes. Although didymo prefers a river environment with clear water flowing over stable substrate at depths sufficient for light penetration to drive photosynthesis, blooms have been found in South Island Lakes. Lake Wakatipu, for example, contains visible didymo on some parts of the lake shore.

What is pandemic human influenza?

All influenza viruses are unstable and constantly changing. New human influenza viruses emerge every year.

Human pandemic viruses are very rare but occur when a new virus, to which humans have no immunity, emerges. Genetic studies have shown that some human pandemic influenza viruses have been derived from avian influenza viruses.

Where was Asian tiger mosquito found?

A single male Asian Tiger Mosquito was trapped at Shed 8 on the wharf at the Ports of Auckland on Friday 1st March 2007 as part of a routine mosquito surveillance program. Investigations are currently underway to establish whether this is a one off event or whether it is part of a localised population.

How do I register my feedback for the TF Gen standard requirements?

How does painted apple moth spread?

Female moths are flightless but male moths can fly and newly hatched caterpillars can "balloon" up to a few hundred metres in the wind using silken threads. Most importantly, the pest can be spread by residents moving plants they’re living in.

What other areas of the world has didymo been found?

Didymo's native distribution is limited to cool temperate regions of the Northern Hemisphere, including the rivers of northern forests and alpine regions of Europe, Asia and parts of North America. Prior to its arrival in New Zealand didymo was not found in the Southern Hemisphere. Over the past twenty years, the distribution of didymo appears to be gradually expanding outside its native range and it is now also found in South America (Chile). Furthermore, even within its native range, there have been reports of excessive growths in areas where it previously existed only in low concentrations. 

How will I know that my Electronic BACC Application has been processed by the Risk Screener?

Once the Risk Screener takes the Electronic BACC Application from the Inbound Messaging queue and processes it, you will receive a consignment reference number and then (assuming they have all the required information) the issued BACC. The Application will now have a unique number within QuanCargo. The BACC will continue to be issued using the current methods of fax or e-mail. Additionally ECN and MPI are working on providing an alternative via ECN.

What is European Foulbrood?

European Foulbrood is a bacterial disease of bees caused by Melissococcus pluton. It is not present in New Zealand, but is found in many other beekeeping countries. European Foulbrood does not form spores, but can be spread on bee products and beekeeping equipment. European Foulbrood is often considered internationally as a ‘stress’ disease - a disease that is usually not fatal to a colony unless the colony is already under stress for other reasons. Healthy colonies usually survive European Foulbrood. Overseas, outbreaks are controlled chemically by feeding antibiotics to infected colonies.

How do people spread Argentine ants?

Anything transported from point A to point B can potentially harbour Argentine ant nests.

Materials that are most at risk of harbouring a nest include rubbish, and garden or nursery products like potted plants, garden mulch, bark chips, and compost.

However, these ants also readily establish nests in cars, caravans, or even aircraft. And in this way can spread themselves across town, or around the country with ease.

Argentine ant infestations are frequently not detected until they have reached the stage of becoming a human nuisance. This may take two years or more. By the time they are detected, the ants are probably well established and may even have spawned sub-colonies that have hitched a lift elsewhere.

Why can’t dog tail injuries simply be treated as and when they occur in the adult dog?

Tail injuries to adult dogs can be treated, although treatment may be prolonged and there can be complications.
