Rush hour commuters who use the Hobsonville-Beach Haven ferry have been forced to find alternative ways home.
Auckland Transport tweeted, "the 5.15pm & 6.15pm Hobsonville-Beach Haven ferry services are cancelled this evening due to a mechanical fault".
Bus replacements to Hobsonville will depart from pier 1 for stranded passengers.
Scheduled buses to Beach Haven will also depart Quay St by the PwC building, Auckland Transport tweeted.
