An Australian woman has described people sneezing on each other onboard the Ruby Princess, which is at the centre of multiple Covid-19 deaths and cases.
Fifteen passengers from the Carnival cruise ship had died, and more than 650 people have been infected. They include passengers and other points of contact.
The cruise ship headed to New Zealand for a two-week cruise around the country.
The Ruby Princess berthed at the port in Napier on March 15, its last port of call in New Zealand before heading back to Sydney.
The Prime Minister said "of course" the obligation on the cruise company was to ensure no unwell person disembarked in the circumstances that were developing.
"I have been advised that those assurances were directly sought by the Medical Officer of Health from the captain directly before individuals disembarked."
Napier Mayor Kirsten Wise reiterated neither the City Council or Napier Port would have had any authority to prevent the Ruby Princess berthing last month.
Such authority of the port company, majority-owned by the Hawke's Bay Regional Council, related to whether ships could berth in certain weather conditions.
