"If you're a regular ferry passenger and use ferry operator discount passes, you may find it better value right now to continue using these products," the flyer says.
Chief operating officer Greg Edmonds told the Herald that multiple trip passes would be cheaper until new deals could be worked out with ferry operators by mid-2013.
That meant it was likely Hop cards would be attractive in the first instance to only casual passengers, who could also use them on trains and for free rides on City Link buses on Queen St and to Wynyard Quarter.
Multiple-trip fares for ferries would be brought into the Hop fold at about the same time as buses were joined to the system from April.
Meanwhile, Auckland Transport has sold about 41,000 Hop cards since introducing them to trains last month at a $5 special price, which will rise to $10 at the end of next week.
