Unlike senior citizens elsewhere, older Aucklanders can travel free on most buses, trains and ferries from 9am until midnight on weekdays.
Weekend travel is free at any time to card-holders everywhere.
But a Waiheke Grey Power member, Margaret Harris, told the panel that Auckland's size meant it could not be compared to other parts of the country and requiring people to hurry home by 3pm would be harsh for island residents among others needing more time for medical appointments and other commitments, including volunteering and supporting young family members.
She said that if the Government wanted cost savings, it should invest in mandatory photo identification on SuperGold cards to guard against fraudulent use by people not entitled to free travel, notably on Waiheke ferries, on which crew members had told her "rorting is rife".
Councillor Mike Lee, who is chairing several days of hearings on Auckland Transport's new public transport plan which will continue tomorrow and next week, said the document would have no ability to change the existing entitlement.
He acknowledged that the plan included a commitment to the Government to review the entitlement this year, but said "a review is not the same as changing anything".
The Herald reported this week that the free travel scheme cost $21.36 million nationally in 2011-12, of which Aucklanders used $10.7 million.
