Lawyer Deborah Manning's hasty exit after tense Duncan Garner interview

The lawyer representing Afghan villagers allegedly attacked by NZ Defence Force soldiers says new information on the incident won't be revealed until later on Wednesday.

When pushed by The AM Show host Duncan Garner, Deborah Manning was adamant the information would be released publicly later today, and abruptly exited the studio at the end of the live segment.

"The allegations are so serious we really need to get this into a proper process, into a proper inquiry," she said.

"This is not something to be run through the media, to be drip-fed. Let's get this into a process."

The legal action Ms Manning and other lawyers are taking is on behalf of the Afghan villagers featured in Nicky Hager and Jon Stephenson's book Hit & Run.

It's a week since the controversial book Hit & Run was released and so far neither side is willing to concede in relation to the allegations from the book.

A letter to Prime Minister Bill English and Attorney-General Chris Finlayson on Tuesday from the lawyers representing the villagers said they had information that "relates to the various claims publicised by the New Zealand Defence Force in a media release" and in a news conference held by Chief of Defence Lieutenant-General Tim Keating on Monday.

They said they expect to provide the information "by or before tomorrow [Wednesday] morning".
