Meat workers at the two AFFCO plants which had not been affected by the company's lockout are on strike on Wednesday.
About 70 members of the Meat Workers Union began the two day strike at 5am Wednesday, at the Wiri plant in Auckland and the Napier plant in Hawke's Bay.
They are supporting some 1000 meat workers who were locked out of AFFCO's six other sites a fortnight ago following a breakdown in negotiations over an employment contract.
Union members at those six plants were on strike earlier in the week.
National secretary of the union Dave Eastlake says Wednesday's strike was kept separate from the earlier one to cause maximum disruption to the company.
Mr Eastlake says the union has received a response from AFFCO to its latest bargaining request, but does not find it encouraging. It will reply to the company in about a week.
AFFCO says the two plants hit by Wednesday's strike will continue to operate with workers on individual contracts, although production will be slower than usual.
