Imports were suspended until the Australian Quarantine and Inspection Service (AQIS) had discovered the cause, the Sydney Morning Herald reported Biosecurity New Zealand as saying.
The ban would remain in place until AQIS came up with another treatment method or achieved the results New Zealand required, a spokesman for the organisation said, adding that AQIS and Biosecurity NZ were in daily discussions.
New Zealand tomatoes were only allowed back into Australia two weeks ago following new quarantine procedures to control the ‘zebra chip’ bacterial disease.
Australian imports account for about 8 per cent of tomatoes sold in New Zealand. Shipments of 3,000 tonnes from the Australian state of Queensland in 2007 were worth A$9m.
