The other employees set to lose their jobs were likely to be based in Auckland, where Heinz Wattie's has sales and marketing operations.
"We strongly suppose that they are white collar workers in Auckland ... it is good news for the Hastings plant."
Mr Muir said workers were shocked by the company's announcement. No information was given out by the company to its workers or their representatives from the Engineering, Printing and Manufacturing Union or Service and Food Workers Union.
"Workers were given no information about these plans before they hit the media. It's incredibly disrespectful behaviour from their employer.
"These redundancies aren't being driven by any desire to improve business, develop better products or create stable, high-skilled jobs. It's all about short-term profit for Heinz Watties' owners."
Tukituki MP Craig Foss yesterday called on Heinz Wattie's to provide more details about the cuts. "We need more information from the company itself, to deal with the uncertainty and angst that a lot of us are sharing at the moment.
"It would be good to have clearer information as soon as possible, so everyone can get on with the great work they're doing across the Bay."
Heinz Wattie's has three plants in New Zealand with two sites in Hastings and a site in Christchurch. A former Heinz Wattie's employee at the Hastings plant, who did not want to be named and was recently made redundant, contacted Hawke's Bay Today yesterday, saying this was the third round of redundancies the plant had seen in the past year.
A Heinz Wattie's spokesman said in response last night the company did not wish to make any further statement.
