The company carried out a $25 million share offer to partly fund its purchase of the Mad Butcher and those shares, which were issued at $1.30 apiece, were allotted yesterday.
Veritas paid for the transaction with $20 million in cash - as well as $20 million in shares - to Morton, who remains chief executive of the retailer.
Darrow said he did not agree that backdoor listings had a bad reputation in New Zealand. "I was very heavily involved with the Charlie's reverse listing ... and that was very successful."
Juice maker Charlie's was acquired by Japanese brewer Asahi for $129.3 million in 2011.
NZX chief executive Tim Bennett, who attended yesterday's listing event, said the Mad Butcher offer had been subject to the same level of scrutiny as any other new listing.
"Given this was the first transaction of its type under the new regulations I think it got more scrutiny than it normally would so I don't think there should be any concerns about [it being a backdoor listing] at all," Bennett said.
He said the fact that the Mad Butcher offer was highly oversubscribed demonstrated the level of appetite for new investment opportunities.
"This is a business that people understand ... obviously it's got some good growth prospects," Bennett said.
There is scope to open 34 new stores over the next five years, Morton has said.
Veritas shares closed at $1.58 last night, which was 21.5 per cent higher than the offer price.
