Devonport sportsman Simon Gundry was baffled by the closure.
"At the most ideal time of the year to sit down there, the place is shut up because somebody has looked at it and said it's dangerous. It's been there for 80 years without a problem."
Four years ago at Christmas, vehicles were banned from parking on the wharf.
A survey revealed "significant deterioration of the basic concrete elements of the structure".
A February 2009 report to the old North Shore City Council said if repairs were not done, the wharf would fail and have to be removed.
For the Rugby World Cup, Auckland Council fitted wooden seats, bait boards and stainless-steel rails.
Devonport Takapuna Local Board chairman Chris Darby said the wharf was "a floating park above the water" and could not be lost to the public.
In addition, it served as the ferry terminal's emergency exit and fire-fighting system.
An early estimate for works was $13 million. Proposals for a major upgrade would be considered by the board in February.
