The types of roles that were most likely to be affected were cooks, stores and menu collators.
But the document said staff would be re-deployed elsewhere in the DHB or Compass Group where possible.
Food preparation at Hawke's Bay Hospital would also change to a "cook chill" method used by Compass Group, which would involve frozen ingredients arriving at the hospital, to be cooked or re-heated in bulk.
However, it was proposed Compass Group would continue to source the majority of its ingredients from within Hawke's Bay, such as bread products from Goodman Fielder and Quality bakers, and local fruit and vegetables.
In March, the Service and Food Workers Union presented a petition opposing the scheme to a board meeting, with more than 1000 signatures, mostly from DHB staff.
Any changes would probably occur from May next year.
