Maori Party president Pem Bird has apologised to the party's co-leader Pita Sharples for a television interview in which Mr Bird suggested Dr Sharples could be replaced by Christmas.
Mr Bird has denied there was any "grand conspiracy" against Dr Sharples and said he was simply discussing options for the future of the party.
"There's no sinister plot, just some naivety. I got caught out a beauty and that blunder of mine caused a whole lot of angst. We've got beyond that. I fessed up to my mistake. What Pita said you can only imagine, but there has been sincere apologies from me."
He was referring to an interview on TVNZ from an airport in which Mr Bird indicated that at the party's usual post-election meeting it could replace Dr Sharples with MP Te Ururoa Flavell, who could also take Dr Sharples' ministerial roles.
The Maori Party will meet on December 17 where the issue of the leadership will be discussed. Both Tariana Turia and Dr Sharples have said they will retire, but Dr Sharples was expected to stay for the whole term.
