Some of the quirkier services available include sunglasses-cleaning by pool staff, white-glove service at afternoon tea and bespoke samphire and eucalyptus bathroom products by Molton Brown.
Last Sunday the ship collided with the Milburn Carrier II at the Port of Timaru. An investigation into the collision had been launched and could take between 12 and 18 months to complete.
A Transport Accident Investigation Commission spokesman said investigators boarded the Seabourn Encore yesterday at Akaroa, spoke to the captain and collected "relevant" materials.
"What we understand is that the Seabourn Encore was docked alongside the Milburn Carrier II when, in high winds, its moorings broke, and it collided with the carrier," he said.
There was some reported damage but no injuries.
The captain of the Milburn Carrier II and port officials were also spoken to by investigators, the spokesman said.
Maritime New Zealand was also investigating. The inquiry findings would be "peer reviewed" before being released.
