Simon Bridges points to Jami-Lee Ross as the National Party leakerby RNZ
Jami-Lee Ross has been identified as the National Party leaker after the party's inquiry into the leak, but the MP is denying he was responsible.
"The report states that the evidence identify points to Jami-Lee Ross as being the person who sent the anonymous text message. I am releasing that report today.
"It is his [John Billington QC's] opinion that on the balance of probabilities the evidence establishes that Jami-Lee Ross was the person who leaked the expenses and the sender of the text message."

Despite the revelations he said he was confident about his caucus and his leadership of the party.
He said these matters were only the result of a single member of parliament and will be dealt with in caucus tomorrow.
"This isn't about me, this is about getting 56 members of parliament, these matters are for caucus to consider," he said.
"The caucus will be asked to consider all relevant matters including his membership of caucus, finally you will recall, Jami-Lee took leave from Parliament given personal health issues, this action is completely separate. I didn't know what the investigation report would contain when the matters were addressed in recent weeks."
But in a series of tweets, Mr Ross said he was not responsible for the leak:
Mr Ross said that Mr Bridges was attempting to pin his leak inquiry on him, because he could not find out who the actual leak was.
He said Mr Bridges was attempting to use his contact with a local police area commander, and a journalist who he said was a friend, as evidence that he was somehow involved.
Mr Ross said it was all because he had been questioning Mr Bridges' leadership decisions.
The investigation, which was carried out by PwC, was looking into the leak of Mr Bridges' travel expenses in August.
In August, RNZ revealed a person claiming to be a National MP had sent a text message to Mr Bridges and the speaker, Trevor Mallard, pleading for the initial inquiry to be stopped for the sake of their mental health.
That led to Mr Mallard pulling the plug on that inquiry saying it was unlikely the text had been sent from anyone outside the National Party.
The National Party then decided to go ahead with its own investigation into the matter.
All National Party MPs signed a waiver to cover communications dating back to February.
But as the staff's employer, Parliamentary Services refused to give permission on their behalf.
Mr Mallard arranged a forensic investigation of emails and relevant databases connected to his office and those staff involved in the preparation of the expenses - about 20 staff in total.
KPMG, who carried it out, concluded there was no evidence that Mr Mallard or any Parliamentary Service finance staff were responsible for the leak.
