Labor is preparing to pass several of the Turnbull government's budget measures the opposition supported during the election campaign.
Opposition frontbencher Brendan O'Connor says Labor will keep its election commitments but has to scrutinise legislation to ensure the government is also keeping its promises.
And if the government was going to put such a premium on keeping promises, it should go ahead with its cuts to superannuation concessions in the form they were put in the May budget - opposed by some conservatives - Mr O'Connor told Sky News on Sunday.
Revenue Minister Kelly O'Dwyer says Labor will obviously see the legislation, but there is no need to negotiate measures already agreed to.
"If they turn around and say, 'no, we didn't really mean it', it means they are playing petty politics, they are playing with our national interest and Bill Shorten simply can't be trusted," she told ABC TV.

Ms O'Dwyer said the opposition already banked the $6.5 billion in savings in its own budget figures.
"The Australian people are sick of these games, they are sick of the politics.
"They want to make sure that the Labor Party works well with the government to act in the national interest."
Social Services Minister Alan Tudge said the government was open to constructive conversations on other measures proposed by Labor or any of the minor parties and independents.
But it was the government's own measures it wanted to get through parliament first, he told Sky News.
