New species of fruit fly found in Auckland

New species of fruit fly found in Auckland

Wellington, February 19, 2019

A second type of fruit fly, (Bactrocera Facialis, the ‘Facialis Fruit Fly’) has been found in a surveillance trap in the Auckland suburb of Otara.


This fly is a different species to the Queensland fruit fly and the detection is not related to the current Devonport situation.

Not an incursion

The solitary male fly was formally identified late yesterday.

No further Facialis fruit flies have been found and at this stage there is no indication there is an incursion of Facialis here.

Ministry of Primary Industries Director General Ray Smith said that Facialis is native to Tonga where it badly affects crops of capsicum and chilli, but appears to be less harmful to other fruit and vegetables.

It is a tropical fruit fly species so New Zealand’s climate may not provide an ideal home for it.

As with the fruit fly in Devonport, we need to determine if it’s a lone specimen or if there’s a population of these flies in the area, Mr Smith said.  


More traps set

 “To do this, We are setting more traps in the area around the find. And, while we look for more flies, we have restricted the movement of fruit and vegetables to stop the spread of any other Facialis fruit flies that may be out there. We are progressively ramping-up activities in the area and will be working closely with the local community,” Mr Smith said.

Biosecurity New Zealand (a Division of MPI) has declared a Controlled Area around the location where the Facialis fly was trapped.

Residents in the Otara area can find full information about what they need to do at 

Movement Restrictions

The restrictions are the same as with the Devonport Queensland fruit fly – whole fresh fruit and vegetables (except for leafy vegetables and root vegetables) cannot be moved outside of the A Zone of the Controlled Area.

This is the area that extends 200 metres out from where the fly was found.

Home-grown vegetables cannot be moved out of a wider B Zone.

Detailed maps of the controlled area and a full description of the boundaries, and full information about the rules are at  

If local people believe that they have seen signs of this fruit fly or found larvae (like white grains of rice) in fruit, they should call the Response Team on 0800-809966.

The work in progress

Mr Smith said that if there are no further detections, the operation is expected to last two to three weeks.

Field crews are busy today setting up a field HQ and placing traps. Work will proceed in the next couple of days installing road signs and distributing other information materials to the public. 

Biosecurity New Zealand has commenced an investigation into how the fruit flies have entered the country.

Mr Smith said that the separate and unrelated Otara and Devonport detections are evidence of the value of a multi-layered biosecurity system.

“Our border controls are extremely tight and effective and they are backed up by an active surveillance system. With these latest two detections that system has put us in the best possible position to respond quickly and ensure New Zealand remains free of these pests.

“That said, it is important we continue to learn and evolve our biosecurity system.  A review of our cargo pathway was initiated in January and is underway. I have now asked Biosecurity New Zealand to commission an independent assessment of the air passenger and cruise pathways,” he said.
