Federal Treasurer Joe Hockey has backed the federal police after they controversially raided Seven Network's offices.
Dozens of officers searched the network's inner-Sydney offices on Tuesday, looking for evidence of a lucrative interview with Schapelle Corby.
The network denies a deal has been made with the convicted drug smuggler.
Mr Hockey was on Wednesday asked whether he agreed with Seven that the raids were "overkill".
"I support the AFP," he told reporters in Sydney.
Seven's commercial director Bruce McWilliam said a senior federal minister expressed "regret" over the raids in a telephone conversation with him.
Communications Minister Malcolm Turnbull later admitted to speaking with Mr McWilliam but denied offering an apology.
Mr Hockey would not be drawn into commenting specifically on the raids, saying it was a matter for the AFP.
"It's not a matter for us," he said.
"I'm sure they would have got a warrant and gone through the prior processes."
Opposition Leader Bill Shorten warned Mr Turnbull from getting involved in the police investigation.
"I think it's smarter politicians, and I suggest to Malcolm Turnbull too, stay out of the police investigation," he told reporters in Melbourne.
"Let that process happen."
Mr Turnbull said Mr McWilliam called him on Tuesday obviously unhappy at the large number of police officers raiding the Seven Network.
He said he then contacted Attorney-General George Brandis then got back to Mr McWilliam to tell him he should talk to him.
Mr Turnbull said Mr McWilliam contacted Mr Brandis who also later talked to Seven Network chairman Kerry Stokes.
He said it was "completely conventional" for a stakeholder to ring him as communications minister about a complaint and for him to refer that stakeholder to the minister responsible.
