Greens leader Richard Di Natale has conceded his deal with the Government to cut pensions is unlikely to reap the party any of its sought-after changes to superannuation.

Cuts to superannuation tax concessions are in the sights of both the Greens and Labor as a potential multi-billion dollar boost to the budget.

But the Coalition has promised no adverse changes to superannuation in this term of Government and Social Services Minister Scott Morrison has stuck by that.

Late yesterday, the Government announced it had struck a deal to pass $2.4 billion in cuts to pensions through the Senate, in return for considering superannuation under the tax white paper process.

Senator Di Natale said the arrangement put superannuation back on the agenda, but that was not how the Social Services Minister saw it.

"We're not going to increase those taxes as the Labor party does, nothing we have done with the Greens does in any way change the Government's position on taxing your super," Mr Morrison told Sky News.

"We will not tax your super."

The Federal Opposition, which trumpeted its decision to oppose the pension cuts yesterday morning, said the Greens had been "completely dudded".

Senator Di Natale admitted the superannuation changes were unlikely to come in while Tony Abbott was prime minister.

"I accept the Government is unlikely to act on those," he told Radio National.

But he argued change was still possible.

"Here's a blueprint for a future Labor government for them to be able to use and adopt," he said.

"It also lays the groundwork should there be a change of prime minister in this government."

The pension cuts will save the budget $2.4 billion over five years by tightening the assets test for the aged pension.

Under the changes, due to be introduced in January 2017, around 170,000 pensioners with modest assets will get $30 a fortnight more, but those with more assets will lose the part pension.

Labor argues the wealthiest couples targeted by the measure receive only $55,000 in super income — even if their super savings are more than $1 million.

It wants those on high incomes to pay more tax on their superannuation, arguing that the top 10 per cent of earners receive more than 30 per cent of the concessions.
