Fresh crow and squirrel legs and feathers were sniffed out at the border by a biosecurity dog.
The gory discovery was made at Auckland's International Mail Centre in a package arriving last week from the United Kingdom.
It had been labelled as craft jewellery, but that didn't fool biosecurity detector beagle Clawson, who sniffed out the illegal goods on the mail belt.
"It was a great interception for Clawson," Ministry for Primary Industries detection technology manager, Brett Hickman.
