Further biosecurity restrictions on the movement of fruit and vegetables in the Auckland suburb of Northcote are being put in place, following the find of a third Queensland fruit fly in the area.
The male fly was found in a surveillance trap just outside the A Zone controlled area, but within Zone B, and was around 270 metres away from the last detection in Northcote.
Biosecurity officials say it is disappointing they have found another fly, but the detection is showing the effectiveness of their surveillance programme.
Importantly, they still have no evidence of an established breeding population.
