An extended secret recording of a controversial meeting between senior One Nation officials has been obtained by the ABC.

It comes after Pauline Hanson said the One Nation executive had dismissed a plan from her chief of staff James Ashby to charge inflated prices for campaign material.

In part of the audio previously released, Mr Ashby said One Nation "had an opportunity to make some money on this [the Queensland election] if we play this smart."

But Senator Hanson said the strategy was never given the green light.

"It was an issue that was raised and it was knocked on the head there and then. So it's never gone on to be implemented at all," Senator Hanson said yesterday.

The fresh recording runs for about seven minutes and does not cover the entire meeting.

There is no evidence in the recording of anyone in the meeting killing off Mr Ashby's plan.

They 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. Well they don't make any money, but you make money," one man says.

Federal Labor has asked the Australian Federal Police to investigate the matter.

Ashby 'embarrassed' by leak

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

"Look the words I guess are embarrassing, there's a lapse there, and I could have chosen better words," he said.

"Am I embarrassed about wanting this party to survive long term? No I'm not."

He maintains he merely floated the idea as part of a "brainstorming session".

He said One Nation never checked whether it would be legal because it had decided not to push ahead with the plan.

"No, we never went down that path of talking about the legalities," Mr Ashby said.

"We simply decided not to do it because it wasn't the right decision. We never went through with it.

"Let's not forget these were secretly recorded conversations in what we thought was an environment where we could safely put any idea on the table, and it wouldn't go any further."

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.
