New Zealand ants found in New Zealand

An Invercargill family feared a biosecurity incident had occurred when they discovered ants inside a tin of Chupa Chups lollipops imported from Spain.  However, after further examination by the Ministry of Agriculture and Fisheries, it was revealed that the ants were... black house ants from New Zealand.  So, basically someone left the lid off a tin and this warrants a newspaper story?
