Latest on Fruit fly detections in the Auckland region

Biosecurity New Zealand alongside industry partners are currently responding to detections of single male fruit flies in Auckland.

Latest situation

The fruit fly response in the Northcote area is about to step up again, with the focus on maintaining controls and resuming baiting and more intensive trapping.

Latest media release here.

Along with the continued movement restrictions, a network of fruit fly surveillance traps which attract male fruit flies have remained in the area over winter and were regularly checked, with the last single male fruit fly detected in the current controlled area on 15 July.

The response has found 10 flies in the Northcote area since February, and while there is yet no evidence of larvae, pupae, eggs or female flies, the continued finds indicate that Queensland fruit flies could remain in the area, albeit at very low levels.

Controlled Area Notices (CAN) have been established in these areas to legally restrict the movement of certain fruits, vegetables and other risk items to prevent any potential spread. Further information can be found on the MPI website: https://www.biosecurity.govt.nz/protection-and-response/responding/alerts/fruit-flies/

Biosecurity New Zealand are underway setting further pheromone traps in the immediate areas surrounding these detections along with inspecting fruit, installing quarantine bins & road signs and distributing awareness information to the public.

At this point there is no indication there is an outbreak of fruit fly or evidence of a breeding population.

Biosecurity New Zealand and industry partners are responding to these detections under the Government Industry Agreement process, GIA. NZ Avocado, like other industry groups, are identifying people within the industry that are able to be travel to Auckland to assist with on-the-ground response operations.

MPI market access teams are in constant communication with international trading partners to assure them that there is no commercial production in these areas and that the response is going as planned.

We will keep you updated of any major developments as these responses progress.
