The current legislation does not give the transport Crown agency boards flexibility in the number of members like other boards have. NZTA must have six to eight, and Maritime New Zealand and the Civil Aviation Authority (CAA) both must have five members. It's not good practice to have an even number of members for voting purposes, but the workload and scope of the NZTA board responsibilities has meant that the default is to have eight members. In the case of the civil aviation and maritime boards, the requirement that there be exactly five members makes for overly complex appointment processes and succession planning. The small number of members has also meant that the workload of members is too high, particularly when facing governance challenges. Recent resignations from the CAA board have cited workload as a key issue. This bill proposes that the number of members of the NZTA board be amended to at least seven but no more than nine members and that the number of members of the Civil Aviation Authority and the Maritime New Zealand boards be amended to at least five but no more than seven members.
