The Ministry for Primary Industries (MPI) is confident the isolated population will be eradicated from Auckland and says insecticide spraying of the five directly affected properties is now complete.

Since the first male fruit fly was trapped in Grey Lynn in mid-February, 14 adult flies have been located with the last find on March 6.

The last detection of larvae in fruit collected from the affected area was on March 13.

MPI's Director of Response, Veronica Herrera says this is good news but is not yet an indication that the flies are gone for good.

"We need some months yet to be quite sure this population has been eradicated. We believe that we will be working in the area until at least the end of November and we will need the community's support for the long haul," she says.

Ms Herrera says going forward, MPI will still need to regularly apply bait to attract and kill any flies present, plus maintain regular trap inspections to make quite sure the flies are gone.

"We are also hugely grateful to the wider community in the Controlled Area who are having fruiting trees in their gardens baited and are having to comply with the restrictions on moving fruit and vegetables."

Fruit flies go to ground over winter and MPI expects to stop the baiting treatments in the controlled area in early June before resuming baiting in spring.

Surveillance traps will stay out over the winter to verify that the fruit fly is gone so international trading partners can be assured that New Zealand is once again fruit fly free.
