A ship from Australia has been refused entry into a Christchurch port.
The LPG tanker Arago remains anchored near Camp Bay in the Lyttelton Harbour as a Covid-19 precaution.
A spokesperson for Lyttelton Port says several of the boat's crew had travelled on a flight earlier in the month where a passenger was subsequently diagnosed with Covid-19.
A doctor boarded the boat yesterday to conduct testing of the crew.
"Once we have the results of that testing we will be able to decide whether an LPC pilot can board the vessel and berth it. It'll remain at anchor until the tests come back," the spokesperson said.
