Major shipping line Maersk is diverting one of its regular services, OC1, away from the Ports of Auckland as cargo congestion in the city continues, Stuff reports. OC1, which links New Zealand to the US east coast, will be skipping Auckland for the next 11 weeks. Maersk would still continue serving Auckland, however, using rail to help shift export to Tauranga. The cargo congestion problem, which has caused gaps to appear on some shelves, is linked to the global rise in demand for goods as well as factory supply issues, due to Covid-19.
