Biosecurity officials are warning travellers to declare high-risk items after two ostrich eggs were discovered in the luggage of a passenger at Auckland airport.
The two eggs, weighing around 1.5kg each were found wrapped in newspaper.
The passenger was fined $400, Ministry for Primary Industries spokesman Steve Gay said.
The eggs posed a high biosecurity risk because they could carry avian diseases, he said.
"And we can't write off the idea that the eggs were going to be used for breeding."
