The first shipment in an export trial of Vanuatu's Tahitian limes arrived in New Zealand in February.
Biosecurity New Zealand said Vanuatu officials had agreed to stop issuing export certificates for the limes until the issues were resolved.
Without identifying the issues, the agency said it was "working closely with local officials to identify and address any gaps in Vanuatu's certification system".
Vanuatu Plant Biosecurity Officer Touasi Tiwok told the Daily Post the temporary stop was an opportunity to discuss "risks" to New Zealand.
