Possum wool is arguably New Zealand’s national fibre. It is astoundingly warm, shockingly light, phenomenally soft, and an absolutely luscious yarn to work with. Best of all, when you knit with possum wool you’re helping to control a pest that has wreaked havoc on New Zealand’s native life. Here’s why possums are such a problem in New Zealand and how Kiwi ingenuity found a way to utilise this wonderful fibre.

New Zealand’s possum problem

Back in the 1850s, some numpty whose name is lost to history had the absolutely idiotic idea to create a fur industry in New Zealand by letting Australia’s brushtail possum loose. This experiment went pretty well for the possums, which were suddenly in a predator free environment. (Well, mostly predator-free. There were those human hunters, but they didn’t hold the possum population explosion back one bit!)

It went less well for New Zealand’s native wildlife and plant life, which became an all-you-can-eat buffet for those pesky possums. Today those 30 million possums will devour 21,000 tonnes of New Zealand’s plant life. And tomorrow they’ll do it again. And again. They’ll devour bird eggs and chicks from species such as kiwi, fantail, weka, tūī, kōkako and kererū. Only 15 years after they arrive in a forest, the forest canopy will collapse due to their hunger.

As if that weren’t enough, possums also are a threat to New Zealand’s cows. It turns out possums are one of the species that can carry bovine tuberculosis. And they don’t just carry it; they spread it to cattle. 75% of TB-infected cattle are found in areas where possums carry the disease.

In order to save New Zealand’s ecology, possums need to be eradicated. Containment is not enough. Wherever they go, environmental devastation follows, which is why possums will never be farmed here.

Sadly, we can’t just buy them plane tickets to Brisbane. Even though the species is endangered in its native land, Australia has no interest in repatriating a passel of possibly tubercular possums. (Australian species that have lived in NZ for a while don’t survive in their ancestral homeland.) So the methods have to be a bit more, erm, terminal.

But from great environmental challenges comes great yarn.

What do possums have in common with polar bears?

In 1991, Phyllis Huitema handed researcher Fazil Khan a pile of possum fur and asked if he could do something with it. Khan, apparently up for a challenge, brought it back to his office at Wools of New Zealand and began to experiment. Within two weeks, he’d created a yarn that was 80% wool and 20% possum fibre. And he began to discover the unique properties of possum fibre.

Though the possum lives in Australia’s tropics, it wears a wool coat that’s designed for the North Pole. Like polar bears and reindeer fur, each possum hair shaft is hollow. Because it’s hollow, even if it gets cold or wet it still holds in heat. (Kind of like how the double walls of a Thermos hold in heat for your coffee!) Possum wool is the third warmest in the world. It’s 55% warmer than merino wool. With such warm fur, no wonder they prefer cool New Zealand to sultry Australia!

You may wonder why, if it’s so warm, there isn’t a 100% possum wool yarn. Unfortunately, the individual hairs are too short to be turned into a yarn on their own. Instead, it’s blended with other fibres to add its magical qualities. 

Possum wool: light and soft as a cloud

Possum wool: Is this the world's softest, warmest, lightest yarn?

Those hollow hair shafts have another side effect: they make possum wool almost ethereally light. On its own, possum fur is so light that it will float away with a soft breeze. This lightness means that as it makes yarn warmer, it simultaneously reduces weight. It makes possum wool yarn lighter and warmer than cashmere.

That’s not the only way possum wool is heavenly! Each strand of yarn has a soft and fuzzy halo. This silky halo isn’t just beautiful to the touch. When manufacturers blend it with cashmere or wool, it also provides protection from pilling and shrinkage. Projects made from possum wool yarns are more likely to keep their shape and stay in good form than most other wool items. You can toss most of them in the wash!

And if you’re familiar with the concept of “blooming,” in which yarns puff up and get softer when washed, possum wool is the all-time blooming champ. You’ll want to use patterns that lend themselves to blooming.
