The search for more Queensland fruit flies will be wrapped up by Easter Sunday providing no more of the pests are found in Whangarei, Ministry for Primary Industries says.
A response by the ministry was put in place following the detection of one of the fruit flies in a surveillance trap in the suburb of Parihaka on April 1.
The Queensland fruit fly is a significant pest of many horticultural crops and home gardens.
Ministry chief operations officer Andrew Coleman said they remained on alert for the possibility there could be a last-minute detection of further flies.
"The response team will swing into action, should this be the case.
