The Engineering, Printing & Manufacturing Union is calling on the Government to urgently implement a strategy to prevent more job losses at factories.
The latest round of redundancies is at Flotech, which the EPMU says has decided to cease production, leaving 70 employees in Manukau out of a job.
Flotech's decision follows moves by Norman Ellison Carpets in Onehunga and Summit Wool Spinners in Oamaru to lay off more than 100 people.
The union says these redundancies show a Government job strategy is needed to support manufacturing.
He says more jobs will disappear if the Government does not help manufacturers stay afloat.
