John Hosking, secretary of Transport, said border management and Ministry of Health have rigid health measures in place for international shipping.
Hosking said there was nil contact between vessel, crew and local workers and all correspondence is via email and phones.
“Crew are not to leave a vessel at any time and Ports Authority and Stevedoring are restricted to wharf,” he said.
“Health protection officers are monitoring all discharge of cargo, crew and local workers.”
Hosking also said the health ministry monitors crew medical certificates prior to arrivals including border management.
Local freight companies earlier confirmed shipping schedules for the Cook Islands will not be affected by the coronavirus crisis.
However MV Olomana is reportedly running late and local freight companies are hoping it arrives at the Avatiu harbour by tomorrow.
