There's confidence from the Ministry for Primary Industries that a bird flu strain will be eradicated. 

Around 80,000 chickens are set to be slaughtered after the disease was found at a Mainland Poultry-owned property at Moeraki in Otago yesterday. 

A second barn tested positive last night, but neither is the strain circulating in wildlife globally. 

MPI Director-General Ray Smith told Mike Hosking they're mapping half a dozen properties with links to the farm. 

He says it'll take a couple of weeks before the outer limits of the virus are confirmed, and expects it to be relatively contained. 

Live or raw poultry exports have been stopped for the time being.
