New Zealanders generally don't think in terms of regions unless they are talking about football; so ''Auckland, New Zealand, Mayors'' (using our place structure as the location and then applying that to the rename) makes it possible to include the cats. for mayors in a new, needed top category for ''New Zealand, Local Government.''
At the moment ''New Zealand, Mayors'' is filed among ''New Zealand, Politicians'' which, from a uniquely N.Z. perspective, would be better reserved for central government.
Having cats. eg. ''Auckland, New Zealand, Mayors'' makes them available in the development of a local one place study.
