German and common wasps are both widespread throughout New Zealand (Clapperton et al. 1994).
Since 1990 the common wasp has further spread to virtually all parts of New Zealand, including Stewart Island. Common wasps are found in most habitats, but reach their highest densities in honeydew beech forests at the top of the South Island, where they have displaced German wasps. The two species coexist in urban and rural habitats.
