One Nation has won a temporary injunction restraining a former official releasing further secret recordings of party meetings, after the ABC aired explosive audio on its flagship 7.30 program.

Lawyers for Senator Hanson applied for an urgent injunction in the NSW Supreme Court on Thursday after a damaging recording previously disseminated by former One Nation treasurer Ian Nelson raised questions about the party's conduct.

The orders were sought against Mr Nelson rather than the ABC directly.

In late May, audio emerged in which Senator Hanson's chief-of-staff, James Ashby, proposed an arrangement for the party to make money from taxpayers and candidates through inflated expense claims.

Last week, 7.30 broadcast a recording of Senator Hanson expressing concern about a news story regarding a $100,000 light plane used by the party for campaigning purposes.

The origin of the plane is being formally investigated by the Australian Electoral Commission following accusations it was donated and not disclosed properly by the party.

On Thursday Supreme Court Justice Francois Kunc made a temporary order restraining Mr Nelson from divulging further secret recordings in his possession.

No order was made against the ABC.

The matter is expected to return to court on Tuesday.

Senator Hanson's barrister, Dauid Sibtain, told the court his client was seeking to restrain the publication of "any other recorded conversations of a party political nature" with Senator Hanson or others.

Justice Kunc said he was concerned to ensure the order was not so wide as to catch "arrangements for dinner or the shopping list for the party fundraiser".

One Nation has been contacted for comment.
