Part of a shipment of insect-contaminated PKE was unloaded in Timaru before the rest of the cargo came to Northport.
When the load of palm kernel expeller (PKE) arrived at Northport, at Marsden Pt, on June 28, a bio-security inspection found it contained living, adult beetles that had possibly come from the PKE's source of origin, Indonesia.
Ministry of Primary Industries (MPI) earlier said the shipment was inspected in Timaru and no insects were found, but until now would not confirm whether any PKE had actually been unloaded there.
MPI confirmed yesterday some of the cargo was unloaded in Timaru before the rest was shipped north.
Palm kernel expeller is the mulched husk left after palm oil extraction, and is used widely in New Zealand as dairy stock food.
