New Zealand First leader Winston Peters said phone records of Revenue Minister Peter Dunne should be examined by David Henry, who is conducting an inquiry into the leak of a report by Rebecca Kitteridge into the GCSB spy agency.
"All the evidence is in those phone records and your minister is gone," Mr Peters called across Parliament's debating chamber yesterday to Deputy Prime Minister Bill English.
"We know there are electronic records that help this inquiry. He has got the power to find them. He should find them."
He also said the inquiry into the leak could be "an in-house snow job".
He said he had written to Mr Henry asking if he had been taking evidence on oath and keeping an electronic record of answers. The Department of the Prime Minister and Cabinet had written back saying they did not want to reveal that information.
