The Port of Tauranga has said its container terminal is running at 50% due to a Covid-19 scare caused by a visiting containership.

The New Zealand port said it would only be able to restore capacity when stevedores have been advised they can return to work after Covid-19 testing.

Officials sought urgent testing of workers who had been in contact with the 5,905-teu containership Rio de la Plata (built 2008), which had at least 11 positive cases on board.
