The remaining $3 million of shares has been reserved for New Zealand resident shareholders who have been on Veritas' share register since February 22, and for franchisees.
Veritas will pay for the acquisition with $20 million in cash as well as an allocation of $20 million in shares to Morton, at $1.30 a piece, who will be the firm's largest shareholder.
The Mad Butcher is gradually transforming its store network to a new format, including a new logo, which Morton said had boosted sales.
He said the business was also phasing out Warriors paraphernalia - a legacy of league-mad Leitch.
"We're very much middle New Zealand now," Morton said. "Some of the higher volume stores are in high net worth areas."
Leitch remains the Mad Butcher's brand ambassador.
Morton said new stores would soon open in Invercargill, New Plymouth, Paraparaumu and Nelson. There was scope to open 34 additional stores over the next five years, Morton said.
He said three-quarters of the firm's franchisees had expressed an interest in buying shares.
The offer and acquisition are subject to approval by Veritas shareholders, which will be sought at a special meeting on April 29.
Veritas' shares closed at $1.80 yesterday.
