There will be a Cabinet reshuffle this week and Nick Smith looks set to be brought back into the fold.
Doctor Smith stood down from cabinet last year during the Bronwyn Pullar ACC scandal.
But John Key says he's done his time.
"Nick is a guy that has been a very successful minister in the past, and yep, there was a little bit of a hiccup and it made sense for him to have a little bit of a time out.
"I've always said I'm not ruling him out as a minister and if I made that announcement on Tuesday I don't think you'd be terribly surprised."
