Board Member Advisory Committee

One of the major responsibilities of the BMAC relates to recruitment to the Board. It is the responsibility of NHAA members to elect the Board. However as the Board’s tasks change and become ever more complex, the NHAA also needs to ensure that procedures are in place that will enable it to access members with the right mix of experience, skills and interests for Board positions, both to fill interim vacancies and to stand for election at AGMs.
