AUSTRALIA'S deadly redback spider has established itself in New
Zealand, posing a significant risk to humans as it threatens to
colonise major cities, researchers have found.
The venomous redback, a relative of the black widow, probably hitched a
ride to New Zealand on imported goods from Australia and had
established itself at sites on both the North and South Islands,
scientists said.
The government's AgResearch institute said in a study published this
month that the redback had proved more resilient to New Zealand's cold,
wet winters than initially expected.
AgResearch scientist Cor Vink said the spider, named for its
distinctive red stripe, threatened endangered native spider and insect
populations.
"Having redbacks in New Zealand is also significant to public health
because they have the potential to become established in a number of
areas that are close to urban populations," he said.
Redbacks are common in Australian cities and Vink said climate
modelling showed they had the ability to thrive in New Zealand's urban
areas.
The Australian Venom Research Unit's website says at least 14 people
have died from redback bites, although there have been no fatalities
since an ant-venom was developed in the 1950s.
