Prices continued to rise at last week's North and South Island wool sale, lifting between 4% and 14%.
In a further sign of market strength, all 24,000 bales on offer were sold at prices which New Zealand Wool Services International manager John Dawson said were higher than expected and which helped push the strong wool indicator towards 600c for the first time since March 1995.
Mr Dawson said the falling New Zealand dollar underpinned market strength.
Compared with the March 3 sale, fine crossbred fleece and shears rose in price by 4%-11%, helped by strong demand from China.
Coarse carpet-type full fleece gained between 5% and 9%, while shorter shears were up by 3% to 8%.
Prices for first lamb's fleece wool rose between 4% and 10%, combing oddments were keenly contested, lifting between 7% and 12%, and shorter types were up by 4% to 13%.
Wool Partners International auctioneer Dave Burridge said continued high demand coupled with low supply fuelled the higher prices.
Good crossbred fleece, 31 to 39 micron, was 4% to 6% dearer, and poorer styles up to 5% dearer.
Second-shear fleece was 5% dearer and crossbred oddments 3% to 5% dearer.
Thursday's sale is scheduled to offer 5100 bales from the North Island and 10,700 bales of South Island wool.
