No more fruit flies have been found on Auckland's North Shore and controls on the movement of fruit and vegetables have been lifted. Biosecurity New Zealand said the decision came after weeks of "intensive trapping" and inspecting hundreds of kilograms of fruit.
The last fruit fly was found almost a month ago in Northcote. The first was found in Devonport on February 14 and a further nine were found throughout Auckland.
Biosecurity NZ said in Northcote, teams had removed fallen fruit from residents' backyards, inspected compost bins, and placed bait on fruit trees to attract the flies.
"With no further finds, we are confident that there are no breeding populations of Queensland fruit fly in the Northcote area, and because of that, the controlled area notices can be lifted today," head of Biosecurity NZ Roger Smith said on Friday.
"All operational activities, including baiting, have been completed. However, as a precautionary measure, we will be keeping in place an enhanced network of fruit fly traps for an extended period.
"If fruit flies are present, these traps will detect them." Smith thanked residents and businesses in the affected areas for their patience.
