Northpower has axed jobs throughout its entire operation as the Northland lines company reviews its costs including ways to reverse millions the business is losing in Australia.
Twelve of the 35 staff made redundant in New Zealand and Australia were based in Northland and included eight linesmen, three mechanics in Whangarei and one in Dargaville over the past six months.
West Coast Energy, Northpower's business which operates in Melbourne and Perth, made an unaudited loss of A$4 million ($4.25 million) in the 2014/15 financial year compared with a profit of A$451,000 the previous year.
Northpower said the redundancies and difficult trading market across the Tasman would not have an impact on its Northland customers because the company, as a group, was performing well and earning well over $300 million a year.
Spokesman Steve MacMillan said sometimes restructuring was needed to plan ahead.
