Wool could be making a comeback. 

The world's largest wool processing facility has reopened near Napier following a $50 million rebuild and refurbishment project  

Associate Agriculture Minister, Mark Patterson, told Mike Hosking there's a big global trend going back to natural fibres. 

He says New Zealand could be at the forefront. 

Patterson says there's a highly motivated cohort of New Zealand entrepreneurs who see the potential in this, and they may want to make money, but they also want to be seen as doing something good for the planet.
