United Future leader Peter Dunne wants to make the SuperGold cards used by older New Zealanders more modern.
He wants them to be a recognised form of identification and to be used for healthcare information. And they should be able to be used on public transport without purchasing other cards.
He announced the "Super-Me" policy at the party's annual general meeting this weekend.
"The idea of Super-Me allows the gold card to go through a much-needed upgrade which will deliver better services to those who use it and empower them to have more control over their information," Mr Dunne said.
People get a SuperGold Card when they get New Zealand Superannuation, which kicks in at age 65, or are on a veteran's pension. The card allows them to claim discounts and concessions.
Cardholders can travel for free on off-peak public transport services in many areas in New Zealand.
Mr Dunne is the party's only member of Parliament. The party has a confidence and supply arrangement with the National-led Government.
