Labour MP Shane Jones has received a draft copy of the auditor-general's report into his 2008 decision to grant Chinese billionaire William Yan citizenship, the report on which his political career hangs.
Neither Mr Jones nor MP David Cunliffe, who is also understood to have received a copy of the draft, will comment on the report.
However, sources suggested Mr Jones was optimistic that its contents were not damaging enough to harm his chances of a comeback to Labour's front bench.
Responses to the report are due within the next fortnight after which the auditor-general's office will release its final report.
That will open the way for Mr Shearer's reshuffle of his caucus. When he asked the auditor-general to investigate the issue and stood Mr Jones down he said he would reinstate him if the report cleared him.
