An organiser at the Engineering, Printing and Manufacturing Union working with dozens of people who stand to lose their jobs, says February's job summit has had little impact so far.
At least 113 people from SCA Hygiene in West Auckland are said to be devastated after being told this week that the ailing plant in Henderson will close early next year.
The Henderson plant specialises in making nappies for the Treasures brand.
An EPMU organiser, Cliff Gunning, says the job summit hasn't delivered for many people as it has failed to save manufacturing jobs.
Mr Gunning says some workers will be able to salvage their jobs if they choose to relocate to SCA Hygiene's plant at Te Rapa in Hamilton, but only about 30 positions could be saved.
