The 930-guest capacity Viking Orion docked in Sydney on Wednesday, the final stop on what is normally a 15-day, 9-stop cruise of New Zealand and Australia. But plans went awry, local media reported, after New Zealand officials asked the ship to leave the country's waters part way through its cruise after finding small amounts of biofoul - plants, algae and small animals - that grow on ship hulls. Tickets for a 15-day Auckland to Sydney cruise departing Jan 10 range from A$8,995 ($6,066.23) to A$29,995 on the Viking website. Viking's Orion is the second cruise ship to fall afoul of New Zealand officials in the past month. New Zealand fisheries officials stopped cruise ship Coral Princess entering the country's waters in December after finding snails on the hull.
