Cigarette manufacturer Imperial Tobacco has announced a proposal to close its Petone Factory, putting 122 jobs at risk.
The factory and its employees will now enter a consultation process.
Kirsten Daggar-Nickson, head of corporate and legal affairs for Imperial Brands, said consumer demand was the reason for the proposal to close the Petone factory.
"Globally consumer demand for our product has declined, so the proposal to close our Petone cigarette factory is necessary for the future of our business.
"In markets like New Zealand, that future is next generation products. So we're transitioning our business, product line and distribution channels to offer these products to smokers that want to transition to a healthier alternative, and we successfully launched an electronic cigarette MyBlu in the New Zealand market last year.
