Hi all,

An end of year update on the update. Our institute has supervised a further cull recently. Divers got only another 15 in late November, but some I think are from a  2nd generation. The few full-grown worms taken were non-reproductive (whereas worms back in August were mostly near gravid). Now the NZ government has announced funding for a 5 year control and monitoring programme.
