A total of 10 Queensland fruit flies have now been caught in central Auckland.
In a statement released today, the Ministry for Primary Industries (MPI) said two more fruit flies had been found since Friday, but officials remained confident they were dealing with a localised population that could be eradicated.
It said DNA testing on all flies to date showed genetic similarity, which meant it was most likely a localised population.
Meanwhile, MPI officers worked closely with Cricket World Cup organisers to mitigate any potential risks associated with Saturday's Cricket World Cup game between the Black Caps and Australia at Eden Park.
Eden Park is within the controlled area which meant those who attended Saturday's match were able to take fruit and vegetables into the stadium, but were unable to take any out.
