Prices deteriorated on an already weak market at last week's South Island wool sale in Christchurch.
The offering was largely dominated by crossbred wool.
With a drop-off in overall quality and little new business being written to off-shore markets, buyers were left buying largely "hand to mouth", PGG Wrightson Wool's South Island sales team said.
Extra demand was generated for the limited offering of new season lambs wool and also any finer wools on offer.
Crossbred fleece (31 to 33 micron) was 1 per cent-3 per cent cheaper and stylish wool was least affected, while 34 micron and stronger was up to 3 per cent -5 per cent.
