About 40 jobs will go from the former Farmlands head office in Hastings as it locks in savings from its merger last year.
Members of the South Island's CRT and the North Island's Farmlands voted to merge in February last year after being told there would be $38 million of net benefits over three years, with 42 per cent coming from the elimination of duplicated systems and resources.
It was described as the perfect marriage, because they were similar organisations but operating in different parts of New Zealand.
Staff were warned last month that the farm-supply company was consolidating functions and many jobs could go.
In a statement, the company said after considering staff feedback on the job losses "the rationale from the proposal around the location of support functions is largely unaffected".
