Westland Milk Products has resumed milk collection from Gloriavale's Lake Haupiri farms, after the Christian community was granted an interim court injunction to prevent the dairy company from withdrawing.
Canaan Farming Ltd says it has received "role model" status in past audits from Westland Milk.
Chinese-owned Westland announced last Thursday it was stopping milk collection from Gloriavale-owned farms from this Monday, in the wake of the Employment Court ruling about work conditions and alleged child labour.
Canaan is one of Westland's biggest milk suppliers, sending about 900,000kg of milk solids a season to the Hokitika dairy factory. Based on next season's average opening forecast of $9 a kilo, this would mean a $9 million loss of income annually for the Gloriavale Christian Community.
Canaan currently has 430 cows providing winter milk, with a further 1500 cows due to calve next month.
