French cruise ship L'Austral has come under investigation for the second time in a month after reportedly hitting a rock in Milford Sound.
The Transport Accident Investigation (TAIC) launched an investigation after the 142-metre- long ship hit an underwater object near Stewart Island in January, Fairfax reported.
The ship, one of many owned by luxury cruise company Ponant, struck another underwater object on Thursday.
"It was entering the Milford Sounds under the directions of the pilot on board when it brushed an underwater object," said Ponant's Australian PR manager Michael Corbett.
