Tui Brewery are looking at scaling down their Mangatainoka Brewery capacity, which may threaten up to 24 jobs.
A media spokeswoman for DB said they had entered a consultation to redevelop the Tui Brewery, involving the installation of a new, smaller brewery "to service the requirements of the region".
She said the move would enhance the Tui HQ experience and generate further tourism.
"If the proposed redevelopment goes ahead, up to 24 full-time and part-time roles would be affected.
"The exact number will be determined at the conclusion of the consultation process.
