General Cable Corporation has confirmed the closure of its manufacturing and support operations in Auckland and Christchurch, with the loss of 170 jobs.
The company had set out a proposal to wind down the local unit in November, with consultation now complete.
Manufacturing at Christchurch will continue until the end of March next year, with sales of special products sourced from the international network of General Cable for special projects to continue after the closure.
General Cable Holdings New Zealand, the local holding company, reported a loss of $8.5 million on sales of $163.9m in calendar 2015, compared to a loss of $17.4m on revenue of $185.8m in 2014.
It had closed its Australian sales office early in 2016 and restructured its New Zealand operation to try to stem the losses.
The North American company had been selling its Asia-Pacific operations, but in November said the remaining Chinese, Australian and NZ businesses would be presented as discontinued in the accounts.
The New Zealand operations had provided copper, aluminium and fibre optic cabling for building and infrastructure in New Zealand and Australia.
