Labour Party leader Phil Goff has told Grey Power members the economy isn't working and there is no long-term plan to fix it.
Both Mr Goff and the Prime Minister tried on Saturday to appeal to voters at the organisation's annual general meeting in Hamilton.
Mr Goff highlighted his party's recent criticism of the cost of the Diplomatic Protection Squad.
And he's given an assurance that state-owned power assets will not be sold by a Labour-led government.
Speaking earlier, Prime Minister John Key said the Government was spending more than ever on health.
He said 12,000 more operations were delivered for those aged over 65 last year than in 2009.
Mr Key also reaffirmed that the superannuation age will not change from 65 while he is Prime Minister.
