A priority pool of up to $3 million will also be reserved for New Zealand resident shareholders of Veritas who were on the share register as of February 22 and to existing Mad Butcher franchisees.
Darrow said Veritas has begun a book build process with institutional investors and NZX broking firms to allow indications of how many shares they would like to purchase.
Broking firm Craigs Investment Partners is underwriting $12.7 million of the share sale and has gained sub-underwriting agreements with Collins Asset Management, a company associated with director Tim Cook, for $2.5 million, and from RMI Holdings, associated with director Phil Newland, for $2 million.
The company has already received firm commitments for $10.2 million of shares, it said earlier this month.
The offer will open during April and remain open until early May. Veritas may also decide to close it early.
Darrow said the offer was subject to Veritas shareholder approval and a meeting would be held in late April to seek approval.
