New Zealand First leader Winston Peters claims there are five sets of electronic records which show that Peter Dunne was responsible for leaking information to a reporter.

Winston Peters was repeatedly challenged in Parliament on Tuesday to release details of the emails between Mr Dunne and a Fairfax reporter if he has them.
Mr Peters says he has information proving that Mr Dunne was the source of the leak, but Mr Dunne denies it and Prime Minister John Key does not plan to re-open the investigation.
John Key ordered an inquiry into illegal surveillance and the current operations of the GCSB by David Henry after the reporter was shown a copy of Cabinet Secretary Rebecca Kitteridge's report in April this year, a week before Mr Key was due to release it.
Mr Henry said Peter Dunne did not fully co-operate with requests made to him relating to emails between the Ohariu MP and the reporter. It found that Mr Dunne and she exchanged 86 emails during the fortnight before it was leaked, but that the MP only provided edited versions of 44 emails.
Mr Dunne is refusing to release the emails which he claims show that he was not the source of the leak. He has leave from Parliament for this week.
Outside the House, Mr Peters said on Tuesday that, though he was aware of five sets of electronic records, he is still trying to get his hands on all of them. He said he has some information, but not enough yet to go public.
"If you haven't got the complete picture - which I admit I haven't got, but I've got enough to say what I've said and know that we're going to make it home. Otherwise, this car's going a long way on no petrol."
Mr Peters said Prime Minister John Key should use his powers to see the emails. But Mr Key doubts he has the legal authority to get them - even if he wanted to - and has decided not to take the investigation into who leaked the report further.
Mr Key said he has already run an inquiry and accepted Mr Dunne's resignation and it is time to move on.
The Prime Minister believes Winston Peters is bluffing that he has seen unreleased electronic evidence of the communications trail between Mr Dunne and the reporter. However, Mr Peters said he has sufficient information to make the allegations inside and outside the House, but insists that Mr Key should be the one answering the questions.
Labour leader David Shearer said the Mr Key is washing his hands of the leak of the sensitive report because it is politically convenient and because Peter Dunne supports the Government.
