The Australian Federal Police says it made a mistake in accusing a lawyer for Channel Seven of a crime as part of a probe into the network's suspected lucrative interview deal with drug smuggler Schapelle Corby.

The error was made in applying for an order which would support warrants to raid the network's Sydney offices.

Armed police raided the offices on Tuesday amid reports Seven had paid Corby several million dollars for an exclusive interview.

Australia has proceeds of crime legislation to ensure criminals do not profit from their crimes.

On Friday, the AFP wrote to Channel Seven's legal representatives, saying it was incorrect to state the lawyers could be suspected of having committed the offence stated in the relevant warrant.

It says the order was issued under Section 246 of the Proceeds of Crime Act.

"The letter refers to the Section 246 Order, which is addressed to 'Justine Munsie or any other employee, Addison lawyers' and states that the issuing Magistrate, His Honour Magistrate Graeme Curran, is satisfied that 'you are reasonably suspected of having committed the offence stated in the relevant warrant'," the AFP said.

"The AFP accepts that this statement was incorrect and it should not have been made. It is a regrettable error, but an innocent word-processing error."

AFP deputy commissioner of operations Michael Phelan says an application form police used was copied from one relating to a different case, but a paragraph that referred to a criminal offence was not deleted.

The AFP says it regrets any "hurt, embarrassment or offence which this error has caused".

"This regrettable error does not invalidate the search warrants, or the order itself," it added.

Seven has previously said it was complying with an order to produce documents under the Proceeds of Crime Act, issued by the AFP on February 11.

Channel Seven has been calling for a full apology for the raids.

Its commercial director, Bruce McWilliam, has also defended the network's right to negotiate with Corby.

"It's not a crime to negotiate with a criminal to do an interview - and it's not a crime to pay a criminal for an interview. Everyone should be quite aware of that," he said.

"The only crime, the only thing that the act permits is that the government can seize any proceeds paid."

Minister knocks back Corby family interview bid

Meanwhile, members of Corby's family have been denied a request for her to take part in a media interview.

Media outlets are reporting that Schapelle's sister Mercedes and her Indonesian husband travelled to Jakarta to present a letter to Indonesia's justice minister, Amir Syamsuddin, asking him to allow Corby to do the interview.

But Mr Syamsuddin reportedly rejected the request on the grounds her parole conditions state she must not cause "restlessness" within the community.

Mr Syamsuddin says the Bali office is handling the case correctly.

Corby has been freed from prison but must remain in Bail for three years under her parole conditions.
