It's been six days since Treasurer Curtis Pitt handed down his budget, but that hasn't stopped the LNP from continuing to dump insults.

Shadow Treasurer Scott Emerson repeated the LNP's line about Labor's budget being a "con job" before delivering a zinger at a press conference.

"The reality is, everyone knows, you can't polish a steaming pile of Pitt," Mr Emerson said.

"And that's what these MPs are going to be doing over the next week."
