There is a beastie known as the common brushtail possum. It is a native of Australia but made its way to New Zealand thanks to European Settlers who hoped to use it as a food and fiber source. This did not turn out to be a good idea. Today there are literally millions of possums destroying natural New Zealand habitat and acting as a vector for bovine tuberculosis, thus threatening both the ecosystem and agriculture.
However, Kiwis are nothing if not resourceful. If Australia gives you brushtail possums, make... yarn! Folks now make a living collecting possums and selling their pelts. Incidentally, Wikipedia tells us that possum is a delicacy in Taiwan, Hong Kong and Malaysia, where they are known as "Kiwi Bear". Who knew.
But on to the yarn. New Zealand is of course famous for sheep and their wool. The possum fur is very fine and light, a little like angora but shorter. When mixed with wool the result is a light, very warm yarn with just a hint of natural heathering.
