The One Nation party's credibility is under renewed attack after an extended recording of a secret meeting revealed more details of a plan to charge inflated prices for campaign material.

The party was embarrassed yesterday when a recording of adviser James Ashby suggesting profiting from campaign materials was leaked.

But One Nation leader Pauline Hanson said the party's executive dismissed the idea.

Cabinet Minister Matt Canavan said a longer version of the tape apparently does not show the plan being rejected.

"Well I am very concerned — their stories are all at sea here, they are all over the place," Senator Canavan said.

"One Nation like to present themselves as some pure and clean force in Australian politics but I think the more and more you see they are just another political party.

"They have people in it that seem to be in it for their own gain and not for the interests of the Queensland or Australian people."

"And they need to be held accountable for these revelations because they are very concerning."

In the recording, the executive can be heard discussing how to make money by selling the candidates an advertising pack.

"We should be selling them these [advertising] packs, because you make money and they make money," on man said.

"Well they don't make any money, but you make money."

Mr Ashby said it was "embarrassing" the discussion had been leaked, stating he had used "a poor choice of words".

Issue was taken very seriously by One Nation: Labor

Sorry, this video has expired James Ashby says he is embarrassed about the words he used at the recorded One Nation meeting.

Labor Senator Murray Watt said the longer recording shows "that in fact this was an issue that was taken very seriously".

"It was not knocked immediately on the head and it was considered in detail by One Nation and there were great discussions had about how this plan could be executed," he said.

Senator Watt has demanded the Liberal and National parties rule out preference deals with One Nation.

Labor has asked the Australian Federal Police to investigate the matter while Prime Minister Malcolm Turnbull told Parliament the matter was "very serious".

"I'll be getting advice from the Federal Police Commissioner, the Minister for Justice, and the [Attorney-General] as we review the media reports in the course of the next day," Mr Turnbull said.

Queensland Premier Annastacia Palaszczuk has pledged to close any gaps in the State's electoral laws if investigations into the One Nation tape expose flaws.

Ms Palaszczuk said serious allegations about senior figures in One Nation submitting false expense claims to the Queensland Electoral Commission have been referred to police and other bodies.

"If the independent investigations of these allegations reveals gaps in our electoral laws that political parties could use to defraud taxpayers, then I will fill those gaps," the Premier said.
