Fruitfly trapping's back-up and running in Auckland, after an Oriental fruitfly was found in Papatoetoe

Biosecurity New Zealand's confirmed the single male fly was discovered in a South Auckland surveillance trap.

It follows the wrapping-up of a six week operation in Mt Roskill last Friday, after the Queensland fruitfly was detected.

Biosecurity New Zealand Commissioner North Mike Inglis says they are unrelated.

He says as a precaution, they'll be putting legal restrictions in place on the movement of fruit and vegetables out of the area.
