A Ngati Tama tribal leader put former Department of Conservation land returned in a Treaty settlement up for security in legal action even as the total value of his tribe's 2003 $14.5 million settlement was being lost.
An Auckland High Court affidavit signed by Greg White, a Ngati Tama commercial leader, sets out that the land could be used to pay legal bills.
Mr White resigned two weeks ago when financial losses under his leadership came to light - in all the tribe lost $19.5 million.
Only $1.5 million remains, plus 1904ha of conservation land, but there is a possibility that the tribe could once again become landless.
The way in which Mr White came to offer the land as security is complex.
