NSW Police have concluded their investigation into the Iguanas Waterfront incident and will hand a brief to the NSW Director of Public Prosecutions (DPP) tomorrow.
Federal MP Belinda Neal and her husband, suspended NSW Education Minister John Della Bosca, were interviewed by police last week over their alleged involvement in an argument with staff at Gosford's Iguanas Waterfront restaurant on June 6.
The pair initially decided to give a statement to police and later agreed to be interviewed after their political leaders intervened.
NSW Premier Morris Iemma ordered Mr Della Bosca to give an interview while Prime Minister Kevin Rudd said he wanted Ms Neal to fully cooperate with investigators.
NSW Police Commissioner Andrew Scipione said police were ready to hand the findings to the DPP.
"We're finalising (it) and looking to hand (it) over in the immediate future," Mr Scipione told reporters.
"We'll do that as soon as we can."
He said police did not set a deadline for the conclusion of the investigation.
"We never said that it would be finished by a day, what we said is that it would be thoroughly and professionally investigated and we would exercise every option when it came to the investigation," Mr Scipione said.
"We've done that and now we're ready to hand it over."
The DPP will decide if there is enough evidence to lay charges and prosecute Ms Neal or Mr Della Bosca.
