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 the painted apple moth?

The painted apple moth (Teia anartoides) is a native Australian pest accidentally introduced to New Zealand. The moth is a minor pest in Australia but poses a serious threat to our gardens, crops, forests, native bush, and the communities that depend on them.

How long does the varroa mite survive away from bees?

Up to five and a half days, but usually much less.

Why can't I bring New Zealand produce back into New Zealand?

New Zealand produce, once it leaves this country, is exposed to pests or diseases in a foreign country. By bringing it back to New Zealand, there is a risk that the produce has been contaminated and would introduce such pests as fruit fly.

What is Tuber brumale (Winter Truffle)?

It is an edible truffle which is associated with oak and hazel trees. It occurs naturally in France and Italy and in other parts of Europe.

During grading is packing of a particular size for Taiwan allowed when other sizes are destined for another market? Sec. 4.2.2.1

Yes. The intention of this section is that potatoes not cleared for Taiwan are not packed at the same time as those that are cleared for Taiwan. The wording of this section has been changed.

Leg-hold traps cannot be used in areas where there is probable risk of catching a companion animal. What is 'probable risk'?

Generally, a risk is "probable" if it is more likely than not to occur.

Whether it is probable that a companion animal would be caught in a certain area is a matter of judgment dependent on the particular circumstances. In trapping operations, both the trapper and the person in charge of or overseeing the operation are responsible for making this decision and for ensuring leg-hold traps are not set where there is a "probable risk". Obvious places where there may be a probable risk include parks, recreational areas, beaches, other places where people walk their dogs and places where pets are known to be kept. Particular consideration should be made in rural areas, in and around riverbeds, in roadside reserves and in known hunting areas, as these are areas where there may be pets and pest control is likely to occur. Please note this list of places where there may be "probable risk" is not exhaustive and is by way of example.

Persons setting leg-hold traps should refer to local bylaws and dog control policies for areas where dogs must be kept on a leash or otherwise controlled. It should be noted that measures may be taken to reduce the risk of capture of companion animals so that there is no longer a "probable risk". Such measures include, but are not limited to, the use of cubbies or other means of exclusion and appropriate placement of traps. Signage can be considered but should not be the only measure.

Will the spread of didymo increase or decrease over the next 10 years?

Since didymo was first detected in Southland waterways in later 2004, it has spread to over 150 waterways within the South Island. It does have the potential to spread to other waterways although it is difficult to know how didymo will act in the future.

What if I am bringing New Zealand wood packaging material back to New Zealand?

Wood packaging returning to New Zealand must meet the requirements of the New Zealand import health standard as it could have been infested whilst offshore with exotic pests.

How does avian influenza spread to humans?

Human cases of the H5N1 strain have been caught mainly by people in very close and prolonged contact with poultry in places such as markets and poultry farms, where there is a high density of different species of bird mixing, and where they are exposed to both live and dead birds and their droppings.

New Zealand does not have similar poultry rearing and marketing environments and there is little risk of people in New Zealand being infected through normal contact with birds.
