New Zealand has temporarily halted watermelon imports from Tonga following the discovery of live fruit fly larvae in a shipment at the Ports of Auckland. The Ministry for Primary Industries (MPI) has suspended imports pending an investigation by Tonga's Ministry of Agriculture and Food, Forestry and Fisheries. The suspension, effective immediately, means watermelons from Tonga will either be held or destroyed until the suspension is lifted. This incident highlights New Zealand's strict biosecurity measures to prevent the entry of fruit flies, particularly the Queensland fruit fly.
