Textiles New Zealand wants more people to get out and trap possums.
The national textiles organisation says the fur is needed to double the export of garments made from a unique blend of possum fur and merino wool.
Chief executive Elizabeth Tennet says possums killed by 1080 poison drops can't be used for the fabric, so trapping is the main source of the fur.
But the current supply is not enough to meet the growing demand. One of the obstacles is the lack of a nationally co-ordinated system for issuing permits.
Ms Tennet says the industry is already worth $100 million, employing more than 1100 people.
