A rump of backbenchers are agitating for the coalition to scrap the legislated rise in the guarantee from 9.5 per cent to 12 per cent.

Labor has seized on the division, accusing the government of chipping away at the retirement savings scheme.

But Mr Frydenberg insists there are no plans to drop the hike in the guarantee.

"Whenever the Labor Party talks about superannuation, it borders on the hysterical," he told Sky News on Thursday.

He said the federal opposition couldn't cop any criticism of super.

"That makes them blind to the reform that we need in superannuation."

Mr Frydenberg said the government passed laws to make super insurance for young people opt-in, consolidate inactive low-balance accounts and cap fees in some cases.

"It seems the Labor Party are stuck in the ideological conflicts of the past," he said.

The guarantee is due to increase to 10 per cent in 2021/22 and then rise by 0.5 per cent in each of the following four years, hitting 12 per cent in 2025/26.
