Insect traps in Whangarei will be checked for the last time on Friday, a fortnight after the discovery of a Queensland fruit fly in the city.
Teams from the Ministry of Primary Industries have been inspecting gardens, rubbish bins, the contents of special fruit disposal bins and home gardens for any sign of the insect.
It's also set up hundreds of extra traps and imposed restrictions on moving fruit and vegetables in a 1.5km control zone.
The ministry says those measures will be lifted at 6am on Saturday if the check comes back clear.
It says there will be ongoing monitoring of traps to make sure the fly does not return.
