The Meatworkers' Union hopes new talks will mean staff from a central North Island lamb processing plant can get back to work by Christmas.
About 100 workers have been picketing outside the Marton CMP Rangitikei plant since 19 October, when negotiations over proposed pay cuts broke down.
The company served a lockout notice on workers who refused to sign individual contracts.
The union says it hopes the deadlock can be broken during talks facilitated by the Employment Relations Authority on 21 and 22 December.
CMP Rangitikei says it has begun its annual process of employing new staff, but they will not fill the roles of the workers who are currently locked out.
