New Zealand Wool Services International says it will resist any move to buy its scours.
The company operates scours near Hastings and Christchurch, which wash wool to remove the grease and impurities. It is the biggest in the country.
WSI says it has been informed by Cavalier Wool Holdings, which owns the only other scours in the country, that it's applying to the Commerce Commission to buy WSI's scouring assets.
Wool Services says it's told Cavalier that its scours are not for sale and it's opposed to any attempt to create a monopoly in wool scouring.
