Why there are so many airpots rendered in New Zealand? Seems to me like a bug.
They're rendered only on zoom 10:

There was recently an import of loads of airports/airstrips in New Zealand. I don't know how accurate this import is, and whether all of those airports actually exist?
Them only rendering at zoom 10 is a bug. One of the Mapnik maintainers has said he's aware of it, though it should probably be reported on Trac: http://lists.openstreetmap.org/pipermail/talk/2011-June/059140.html

By looking at satellite imaginery, I see rocks on majority of them. There are no even roads to them. And in any case, 200 airports around a city with like 2km between them? o_O
I looked at the data and see that nodes with relevant tags do exist there, so it seems like a bad import.

I see a lot of grass strips.
Technically, if you can land a cropduster, it's an aerodrome.

It seems that a lot of the airports on OSM don't even exist or may have existed at one time and don't exist anymore. Don't be afraid to delete any airport nodes placed where there doesn't appear to be any sign of an airstrip on the satellite imagery.
