The removal of second piece of Rena's 700-tonne accommodation block has been put on hold as a result of the ship's stern moving during Cyclone Lusi.
However, salvors are preparing for the removal of a 600-tonne port side piece of the wreck.
The first piece of the accommodation block was cut and lifted from its location on Astrolabe Reef almost two weeks ago. It was initially thought the second piece of the accommodation block could be lifted from the wreck after divers had a clear seven-day window to survey and reset the lifting chains on the new piece.
Last week divers noticed the position of the Rena's stern had changed after Cyclone Lusi and spokesman for Rena's owner and insurer Hugo Shanahan said they would not progress with the second cut and lift of the accommodation block until an underwater sonar survey could be completed on the wreck.
He said it was something they had to do before they could make any decision to move forward.
