South Auckland engineering firm Flotech says manufacturing formerly carried out at its Wiri plant will be outsourced to North America and Europe when the factory shuts down this month, at the cost of 61 jobs.
Head of products Steve Rowntree said the factory, which makes gas processing equipment, would be gradually decommissioned over the next two weeks.
Flotech would retain 24 workers in New Zealand after the closure, including research and design staff.
Rowntree said costs, particularly freight, had become too high for the factory to remain in operation.
"Most of our products are being sold in Europe or North America and most of the parts that go into our plant [in Auckland] get purchased from the USA or Europe as well."
