Mulesing is the most consequential ethical issue in merino wool, and the one most consumers have never heard of. Here is what it is, where the industry actually is, and how we know our wool is mulesing-free — without leaning on a certification.
What is mulesing?
Mulesing is a surgical procedure where strips of skin are cut from the rump of a young merino sheep to prevent flystrike. Flystrike happens when blowflies lay eggs in moist wool around the rump and the hatching maggots feed on the sheep's flesh — a serious welfare issue in itself. The procedure is intended to leave smooth scar tissue that does not retain moisture, eliminating the conditions flystrike needs.
It works. But it is also a painful, invasive procedure, frequently performed without anaesthetic. Modern alternatives — selective breeding for plainer-skinned sheep, careful crutching, improved fly management — achieve the same outcome without the welfare cost.
The state of play across NZ and Australia
New Zealand: Mulesing was banned on 1 October 2018 under the Animal Welfare (Care and Procedures) Regulations. The ban was uncontroversial because NZ farmers had largely transitioned to alternatives by then — selective breeding for plainer-skinned merinos, careful crutching, and better fly management.
Australia: Australia produces around 75% of the world's merino wool and the procedure is still legal there, but the industry has moved a long way. Pain relief is standard during mulesing today, and the share of farms that have transitioned to mulesing-free methods is growing year on year. There is a meaningful and rising volume of certified mulesing-free Australian merino, and many of the most progressive Australian farms have led the welfare conversation.
The honest summary: New Zealand's regulatory position is simpler, but "NZ good, Australia bad" is a lazy read of the actual picture. What matters more than the country is whether you can verify how the sheep are managed.
How Smart Merino guarantees mulesing-free wool
We do not buy wool through anonymous commodity channels. We buy it from farms we have direct relationships with — farms in New Zealand and Australia where we know the people, know the management practices, and can trace the fibre from sheep to yarn.
That direct line is what allows us to guarantee mulesing-free wool. Not a logo on the swing tag. Not a certificate paid into a third-party scheme. Just knowing where it comes from, because there is no middleman between us and the farm.
The shortest possible supply chain isn't the one with the most certifications. It's the one with the fewest hands.
What that means in practice
- Every Smart Merino garment is sewn, knitted and finished in New Zealand
- The wool itself comes from farms in New Zealand and Australia we source from directly
- We know the farmers and the farming practices on every farm we use
- No commodity-exchange wool. No anonymous supply.
What to look for as a consumer (in any merino brand)
- Direct claims about sourcing. Brands with real traceability will name the farms, regions, or country of origin clearly.
- Specific mulesing language. "Non-mulesed", "NM", or an explicit policy statement — not vague "ethical wool" copy.
- Manufacturing transparency. Where is the yarn spun? Where is the garment sewn? Brands that won't say usually have a reason.
- Ask the brand. Brands with nothing to hide will tell you exactly where the wool comes from. Vague answers are an answer in themselves.
Frequently Asked Questions
What is mulesing?
A skin-removal procedure on young merino sheep to prevent flystrike. Modern alternatives include selective breeding, crutching, and fly management.
Is mulesing legal in New Zealand?
No — banned since 1 October 2018.
Is mulesing still done in Australia?
Legal but increasingly less common, with pain relief now standard and a growing share of mulesing-free farms.
How does Smart Merino guarantee mulesing-free wool?
Direct relationships with the farms we source from — in both NZ and Australia. No middlemen, no anonymous supply.
Why no ZQ or RWS certification?
Certifications exist to verify supply chains brands can't see directly. We don't need that layer because we know our farmers ourselves.
Mulesing-Free, Direct From the Farm
Wool from farms we know personally. Garments made entirely in New Zealand. No middlemen between sheep and seam.
