"We believe the Government should set an example to our nation and the rest of the world by supporting our sheep industry and use only woollen insulation and carpets in all future renovations and new builds, Parliament offices and commercial building."
The value of the coarse wool produced by most North Island farmers has dropped dramatically since 1987 when Journeaux and her husband John had their first sheep and beef property.
In those days it cost $1.10 to $1.20 to shear a sheep, and wool sold for $4 or $5 a kilogram. Selling wool, rather than selling meat, was the main reason to farm sheep.
These days the Journeauxs have their sheep sheared twice a year, and it costs $4.50 per sheep each time. Each sheep grows five to six kilograms of wool a year, which sells for about $8 - less than the cost of shearing.
Most of the wool is exported and it's a very good product, John Journeaux said.
"It's frustrating. If you try and buy anything made out of wool, it's not cheap. Somewhere along the line people do make money out of it."
He supports a push to make wool mandatory in Government-funded buildings.
"With the worry of climate change and pollution nowadays, it's a great opportunity to go back to a natural, long-lasting product."
