National Executive Committee

National Executive Committee

The National Executive Committee (NEC) conducts the affairs of the IAIAsa affiliate on behalf of its members by steering the strategic direction of IAIAsa and forming a link to the international body of IAIA.

The NEC shall consist of at least five Office Bearers: the President, the Past President, the President-Elect, the Secretary, the Treasurer, and a number of additional NEC members including a student member representative, each Branch chairperson (elected regionally) and such other ordinary members who may be elected and who may be assigned portfolios by the NEC. The NEC members are elected for two-year terms of office, which start on 1 March to the end of February. The term of office of the President Elect shall be extended to cover such person’s time as President Elect, President and Past President.

The NEC meets at least twice in person annually, within the first months (Strat Plan) of the financial year to elect a new President Elect (i.e. who starts his/her term 12 months later as President) and to plan for the coming year, and then again for mid term traditionally at the time of the IAIAsa National Conference. In addition a NEC teleconference meeting is held every second month to discuss progress of tasks and any other matters requiring attention. The Plan set at the Strategic Planning (StratPlan) meeting is largely implemented at branch level, where most interaction occurs with the IAIAsa members. The current committee members and portfolios are as follows:
