"The vessel has been operating in the South Pacific for the whole summer and all crew on board meet health authority requirements," he said.
All ships - cruise and cargo - visiting the Port of Tauranga strictly follow Ministry of Health regulations regarding the health status of people on board, the company said.
The rules were administered by the public health unit of the Bay of Plenty District Health Board.
Within 24 hours of expected arrival in New Zealand, ships must declare if there is any illness on board and they are not allowed to berth unless public health officials are satisfied there is no risk, the company said.
Ship captains must also declare whether the ship or anyone on board has been in a Covid-19 hot spot within 14 days. If so, those people would be banned from coming ashore.
