A Christchurch plant is closing, with the loss of 50 jobs, after Schneider Electric's announcement that it is shifting operations to Australia and Vietnam.
The plant, which produces light switches and power plugs, was formerly part of Christchurch company PDL.
The E tū union's industry co-ordinator, Phil Knight, says a number of workers have been with the firm since its days as PDL, with one employee clocking up 42 years.
"We've seen a string of these closures, and every time it's a blow for our members and the economy," he said.
The announcement comes a fortnight after ABCorp announced it was closing its Christchurch plastic card factory and relocating abroad.
