Cruise New Zealand says this country is missing out on tourist revenue because of the lack of infrastructure at ports.
Executive officer Kevin O'Sullivan said the decision by P&O Cruises Australia to deploy a smaller ship than what it had planned was a sign of dissatisfaction with facilities here.
P&O had planned to build a ship specifically for the Australia and New Zealand cruise market that would have been capable of carrying 4200 passengers.
''The good news is that P&O will still bring the 3000 passenger Carnival Splendor to Australia and New Zealand in 2019, but it has cited a lack of infrastructure progress in the region as one of the reasons for deferring the build of a bigger ship,'' he said.
Slow progress in building berths for larger cruise ships in Auckland, as well as even slower decision making to provide a cruise ship berth in Lyttelton, was hampering the growth of the cruise ship industry in New Zealand, said O'Sullivan.
