Four research projects have been launched to support efforts to eradicate yellow-legged hornets from New Zealand.
Science Minister Penny Simmonds and Biosecurity Minister Andrew Hoggard announced the projects, which are being carried out by researchers at the Bioeconomy Science Institute Maiangi Taiao.
One project will use modelling to pinpoint Auckland locations where hornets are most likely to persist, guiding ground surveillance teams. The modelling will draw on around 17,850 public reports received since the hornets were first detected on Auckland's North Shore last year.
A second project will examine how yellow-legged hornets might affect rural and non-urban environments, while a third focuses on engaging Māori communities about the threat. The fourth project will produce guidance for honey and pollination industries, incorporating international experience and lessons from New Zealand's response.
Responders have found and destroyed 132 nests and 77 queens since detection. No hornets have been sighted since early April, though Hoggard said "continued vigilance is needed from the public and intensive searching and trapping is ongoing".
The Ministry of Business, Innovation and Employment is funding the work through the Strategic Science Investment Fund. Even with no spring detections, extended surveillance with no sightings will be required before eradication can be declared.
