The Conservative Party has organised its annual general meeting - scheduled to last an hour.
It appears to have been arranged by supporters of former leader Colin Craig, and the aim is to appoint a new board.
Mr Craig's erstwhile colleague and now bitter foe John Stringer on Friday revealed the plans for the meeting.
It's due to start in Auckland around 9am tomorrow.
Mr Stringer says he's been told he isn't entitled to attend, but he's going anyway.
He wants an extraordinary meeting to be held later this year or early next year.
Mr Stringer on Thursday filed a $1 million defamation case against Mr Craig.
Mr Craig launched a $750,000 defamation case against Mr Stringer in June.
Mr Stringer, a former interim chairman of the party's board, is claiming he was defamed in a pamphlet Mr Craig issued in July titled Dirty Politics and Hidden Agendas.
Mr Craig claims Mr Stringer defamed him on 31 separate occasions.
They both vigorously deny the allegations.
Their problems go back to the chaotic collapse of the party's executive and board in June this year.
Mr Craig resigned amid allegations of inappropriate behaviour and appears to be trying to make a comeback.
Mr Stringer announced he was interim chairman of the board after all the others quit, but subsequently resigned the position.
He says he's considering standing for the leadership.
Mr Craig led the party in the 2014 election campaign.
It won 3.9 percent of the party vote, not enough to get MPs into parliament.
