The owners of a multi-million dollar superyacht say they are "shocked" after it was destroyed in a fire at an Auckland boat-yard.
Up to 90 firefighters battled the blaze, which occurred around 1.30am on Sunday at the McMullen and Wing yacht and boatbuilding business in Mt Wellington.
The luxury 50 metre, 24-berth vessel, Star Fish, was three-quarters complete and due to be delivered to its overseas owners next year.
Rob Chappelhow from Aquos Yachts in the UK said: "We're absolutely shocked and stunned. We're keen to get to the bottom of what's gone on.
"But it's devastating news for everyone involved."
The guide price on the Aquos Yachts website for the superyacht was $49.5 million ($60.9m NZD).
The luxury vessel - which included an infinity pool, bar and gym on board - is completely destroyed.
The Star Fish was due to be launched in March 2013.
Speaking anonymously, the managing director of the long-established boat-yard, said those who had spent countless hours working on building Star Fish were also devastated by the extent of the damage.
Some were in tears when they heard it had been gutted by the fire, he said.
The investigation into the blaze continues today.
