Foreign Affairs Minister Winston Peters is not aware of any documents relating to New Zealand included in a major Australian security leak.
Two filing cabinets filled with hundreds of highly classified Australian government documents were found at a second-hand store in Canberra, which sells ex-government furniture on the cheap.
It's one of the biggest security leaks in Australian history, but Mr Peters says there's, so far, no evidence that information about New Zealand security was in the files.
"We are aware of that being a concern, but we've got no evidence at the moment that that's happened," he said on Thursday.
The Cabinet Files contain thousands of pages, obtained by the ABC, reportedly span five separate governments over almost a decade.
Mr Peters had been informed about the leak by his department, but had not been alerted to anything that may be of concern to New Zealand.
"You can't be satisfied, until you know that they have given us the requisite advice, if they've discovered something," Mr Peters said.
"At this point in time, not all documents have been looked at by the Australians."
The cabinets, which were locked at the time they were purchased, sat untouched for months, before they were unlocked, using a drill.
The ABC, which has not revealed its sources, broke news of the leak earlier this week.
On Wednesday, the Australian Department of Prime Minister and Cabinet announced an urgent investigation into the leak.
