Authorities are confident restrictions on fruit movements in west Auckland will be lifted this weekend with no new discoveries of Queensland fruit flies.
Results from trapping are expected to be completed by Friday afternoon.
Intensive surveillance has not located any more fruit flies since one of the insects was discovered in Avondale on May 8.
Ministry of Primary Industries (MPI) deputy director general Andrew Coleman said authorities were confident the single male fly found was isolated.
"Once the results from the lab have come back a decision will then be made to remove the controlled area notice and restrictions, unless another fruit fly is found," Mr Coleman said.
