Treasury staff have mistakenly given copies of this year's Budget to journalists and political commentators early.
The fresh blunder comes hot on the heels of the Treasury allowing National Party staffers to search for details of the Budget on its website days before its official release.
Academic Bryce Edwards - who writes a popular politics column for the Herald - said this morning he was given Budget documents early by officials who thought he worked for Treasury.
Officials took it back when they realised their error, he said.
