Exporter Wool Services International says strong demand and limited supply is still driving up the prices, helped this week by a slight drop in the value of the New Zealand dollar since the last sales a week ago.
The price of coarse carpet type fleece rose 2.5% - 5% in the sales on Thursday.
Fine crossbred wool prices were up to 1% higher.
Coarse crossbred wools strengthened by up to 2%.
However, a small end of season offering of finer mid micron wools eased 4% - 6%.
Of the more than 7000 bales on offer, 96% were sold.
Buyers from China, India and Australasia continued to dominate the market.
