The wool levy was stopped after farmers rejected it in a very close vote in a referendum in 2009.
Now Beef + Lamb New Zealand will seek an independent evaluation of the impact on the industry.
The move follows a successful remit to this year's annual meeting. Farmers supported a call to evaluate the result of discontinuing the wool levy and to investigate whether a future collective investment would add value for woolgrowers.
The results of investigations into a possible future collective investment will come back to next year's annual meeting.
Beef + Lamb New Zealand still funds some wool-related activities from reserves left over from former levy payments.
