The NEC has said the trade union federation divisions remained unresolved because the factions ignored the recommendations of the ANC task team.
Divisions in the Chemical, Energy, Paper, Printing, Wood and Allied Workers' Union over investments and a trust for members have spilled into court.
Unions are likely to accept the state's latest public sector wage offer and bring to an end seven months of negotiations and the threat of a strike.
Cosatu's policy is one sector, one union but there could be two, metalworker's union if Numsa has its way.
Cosatu boss Sdumo Dlamini says the rebel unions had only identified unity and cohesion as issues they want to be addressed, not electing new leaders.
Trade union federation says it had planned to hold the meeting, but Numsa says legal intervention was needed to compel it to do so.
Zwelinzima Vavi will not appeal his expulsion from Cosatu as general secretary, unless it holds what he calls a legitimate congress.

The internal money problems are probably most damaging, as they reveal a state of financial mess more dire in magnitude than what Vavi is accused of.
With mounting debts hanging over its head, the future existence of the SA Commercial, Catering and Allied Workers Union remains under threat.
Allegedly the main reason for Vavi's expulsion was his "failure to fulfil his duties as secretary".
Cosatu's Zwelinzima Vavi will not be resigning and says he will return to the trenches to try and mobilise workers.
