Timber processing company Carter Holt Harvey is proposing to cut the staff at its Marsden Point plant in half as it grapples with unprofitability.
The Herald understands that there are currently 325 staff working at the plant and the company is proposing to restructure the business and reduce staff numbers to 160.
This comes following the closure of the company's Whangārei mill in February, where more than 110 jobs were axed.
Carter Holt Harvey confirmed that it had begun consultation with staff in its laminated veneer lumber (LVL) business to restructure tit into a smaller domestically-focused operation.
"The proposal reflects our serious concern that the export part of the LVL business, which accounts for approximately 70 per cent of our production and sales volume, is unprofitable and the business as it operates today can't continue," Prafull Kesha, chief executive of Carter Holt Harvey, said in a statement.
