Federal Labor says the government is more concerned about changing the voting system than boosting the economy.

Treasurer Scott Morrison will be the minister in charge of introducing a bill to change the Senate voting system on Monday.

"Those opposite spend every waking hour arguing about each other's jobs and not a moment on the jobs of the rest of Australia," Labor frontbencher Tony Burke told parliament.

Introducing the bill, Mr Morrison told parliament he represented the Special Minister of State in the lower house.

"The bill proposes to simplify and improve the Senate voting system," he said.

When Mr Morrison concluded his speech, Mr Burke rose to seek parliament's permission for the treasurer to immediately give a 46-minute speech to outline the government's economic plan.

He also sought permission for shadow treasurer Chris Bowen to be given 46 minutes to speak on Labor's economic plan.

The opposition chose 46 minutes because that was the length of Mr Morrison's National Press Club speech last Wednesday, which was criticised for not including any new initiatives.
