Ports of Auckland has been granted clearance by immigration authorities to bring in five critical workers who could help clear its massive backlog of cargo, Stuff reports. Spokesperson Matt Ball confirmed the workers were busy applying for their visas, but they had to do it themselves and were all at different stages. Meanwhile, Custom Brokers and Freight Forwarders Federation president Chris Edwards is confident that the cargo problem will be fixed in four to six weeks with the arrival of the port workers.
