Auckland's weekend ferry services are virtually sunk, with multiple cancellations and timetable disruptions.

Operators Fullers360 says due to crew shortages all Half Moon Bay and inner harbour loop services including Birkenhead, Bayswater and Te Onewa Northcote point are not running on Saturday and Sunday.

Instead there will be bus, uber and taxi replacements. They're also warning of possible delays to Waiheke, Hobsonville Point and Devonport services.
