Kiwi pest-control authorities are fighting a holding-action against a car-sized wasp-nest.
Ecology professor Robin Fordham says the nest will have a complex structure and all the wasps won't have been killed.
The Massey University associate professor says the nest probably has separate, walled-off internal sections.
It's also possible Queen wasps have settled nearby after escaping from the attack, he says.
