Thanks Leigh. I hope you are right . . . But the following from:
https://www.cruisemapper.com/ports/dunedin-port-21?tab=schedule&month=2024-01#schedule
Port Dunedin cruise ship schedule shows timetable calendars of all arrival and departure dates by month. The port's schedule lists all ships (in links) with cruises going to or leaving from Dunedin, Port Chalmers, New Zealand. To see the full itineraries (ports of call dates and arrival / departure times) and their lowest rates – just follow the corresponding ship-link.

Also I am sure I also saw it in the Ponant details but will look later.
Mike.
