Last month the company said it had allocated $22 million of shares in the offer available to institutions and clients of broking firms, at $1.30 a share.
The remaining $3 million of shares had been reserved for New Zealand resident shareholders who have been on Veritas' share register since February 22, as well as franchisees.
Veritas will pay for the acquisition with $20 million in cash as well as an allocation of $20 million in shares to Michael Morton, who bought the business off founder Sir Peter Leitch in 2007.
Morton remains the firm's chief executive and will be its largest shareholder following the acquisition.
The Mad Butcher operates 36 stores, which generated $150 million in sales in the year to March 2012.
Earlier this month 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.
Veritas shares were unchanged at $1.45 just after midday.
