This looks like a bug. GeoPlanet has zip code children for each of
the counties covered by New York City except Manhattan (New York
County). The Manhattan zip code areas are parented by New York City.
We'll investigate the cause of this issue.

Since New York City appears to have only Manhattan zip code areas
among its children, you may assume that a zip code area parented by
New York City (woeid 2459115) is actually parented by Manhattan (woeid
12589342).

Thanks for bring this issue to our attention!
