It is scheduled to be held in Harare on December 22.
Notices of the meeting were sent out in the last few days on the instruction of Mashonaland's general manager Givemore Makoni, who told AFP: "We are definitely going ahead with this."
The province is alleging that the ZC board acted outside the constitution by unilaterally rebranding the Zimbabwe Cricket Union into Zimbabwe Cricket when the many stakeholders in the country should have been consulted, especially the four provincial associations and others such as Country Districts organisations.
The MCA called a media conference on Thursday to give details of its complaint, whereupon Chingoka put out a statement saying the MCA personnel organising the conference had no mandate from the MCA to do so.
But Makoni said: "It was a Mashonaland board decision and therefore properly authorised."
Chingoka threatened in a statement to consider legal action and also invoke the labour laws by issuing suspensions against Cyprian Mandenge and Claudius Mukandiwa, who chaired the conference.
He did, however, explain in a letter to provincial chairmen that "the (rebranding) exercise was rushed in order to capitalise on the England tour. I profer apologies for proper procedures not being followed. My recommendation is to review this matter in the near future."
"But that's simply not good enough" said Makoni.
