St John is aiming to save $30 million to survive the economic impacts of Covid-19.
The organisation says it's because of a projected loss of fundraising revenue - and to address a long overdue pay correction for staff in the next year.
In an internal memo, seen by Newstalk ZB, the organisation has told staff it's forecasting a significant deficit in the next financial year.
A St John spokesperson has told ZB job cuts are on the table.
