Asian Paper Wasp
(Polistes chinensis) in New Zealand
History and Background
The Asian Paper Wasp (Polistes chinensis) is a more recent arrival in New Zealand, first discovered in the 1970s. Unlike Common and German Wasps, it is a semi-social species, meaning its colonies are smaller.

Larger than Common and German Wasps, reaching up to 25mm in length.
Where Are They Found?
Common in the North Island but increasingly spreading south.
Prefers warm, sheltered environments, including eaves, fences, and bushes.
Frequently found in urban gardens and rural areas.
Why Is It a Problem?
Preys on native insects, impacting biodiversity.
Nests in high-traffic areas, increasing human encounters.

sting when provoked.
How to Identify a Nest
Small, open honeycomb-like nests often attached to buildings, tree branches, or fences.
Less structured than the enclosed nests of German and Common Wasps.
Can be identified by visible wasps tending to larvae in the open cells.
Control Methods – How to Get Rid of Them
Remove small nests early in the season by scraping them off structures.
