The government has released its plan to contain and eradicate mycoplasma bovis cow disease.

Prime Minister Jacinda Ardern confirmed yesterday the government will attempt to eradicate the disease, and it's anticipated 126,000 cows will need to be culled in addition to those being culled at the moment. The plan is expected to cost $886 million over 10 years. The government is set to foot 68 percent of the bill, with Dairy NZ and Beef and Lamb NZ set to meet the rest. Some experts fear the decision will come at a huge cost.

Farmer Jamie MacKay explains what could be in store with the cull.

“They're not going to go in and wipe out everything overnight. It's a phased process so we're hearing that this may take through til June or July and once again reassess.”

So far, 38 farms have been affected by the cow disease.
