Brinks Chicken, which has 398 employees at four processing plants in Christchurch, Karaka, Tuakau and Mangere, says it has reached conditional agreement for sale to Tegel Foods.Some rationalisation is expected if the deal goes ahead.The agreement followed detailed discussions, with the terms commercially confidential and subject to approval by the Commerce Commission, a Brinks statement said today.A decision by the commission was likely to take several months.Formal consultation would take place with union representatives and Brinks staff on the potential implications of any deal."If a deal is finalised, some rationalisation will inevitably occur, given that Tegel operates its own processing facilities, " the statement said.Brinks would continue a business as usual approach ahead of the commission decision. If a deal was not finalised, then it was Brinks' intention to continue with its existing operations.Regardless of whether any deal was finalised, neither Brinks nor Tegel anticipated any adverse impacts on processed chicken
