decision-making responsibility for a non-regulatory activity of the Auckland Council should be exercised by its governing body if the nature of the activity is such that decision making on an Auckland-wide basis will better promote the well-being of the communities across Auckland because—
(i)
the impact of the decision will extend beyond a single local board area; or
(ii)
effective decision making will require alignment or integration with other decisions that are the responsibility of the governing body; or
(iii)
the benefits of a consistent or co-ordinated approach across Auckland will outweigh the benefits of reflecting the diverse needs and preferences of the communities within each local board area.
