Welcome to the New Zealand Wool Classers Association

Fostering and supporting quality education, harvesting and presentation standards in the wool industry. A home for all involved in wool growing, handling, grading and classing.

Our role in the wool harvesting industry is to promote a high standard of wool classing & wool preparation. To achieve this outcome we maintain a register of qualified classers, hold field days, communicate through newsletters, email, Facebook and this website. NZWCA also maintains a strong role in promoting education for the wool industry.

Education for the Wool Industry

We can advise that there are 30 students studying the 2020/21 Certificate in Wool Technology delivered by Southern Institute of Technology (SIT). The tutors for this course are Laurie Boniface and  Richard Gavigan. Due to the Covid-19 Virus the proposed course starting in July 2020 has been cancelled and the next course is due to commence in February 2021. For more information about the course:

This course is in the final steps of being approved and discussions are taking place with SIT to deliver the course with input from the wool harvesting industry


A number of qualifications are registered covering shearing, wool handling and wool pressing but at present delivery of these is on hold pending industry and government discussion.


Examples of foreign articles found in wool bales, on display at the Christchurch Field Days.


This photo shows us the major problem that the industry has with foreign articles turning up in bales of wool at our local wool scours. No doubt wool shipped greasy will contain the same foreign articles.

In the past this unnecessary problem has caused a number of issues that include damage to wool scour machinery and contamination of wool products going through the manufacturing process. When these contaminates such as clothing, towels or plastic go through to the manufacturing stage it can create financial claims back to the Buyer/Scour.

This is a problem we all can fix by being observant in our workplace and recognising contamination problems before they arise.


All brands are to be removed from wool and kept separate. Last season some branding products were not scourable and created large financial claims and in some cases, wool could not be sold.
