The spokeswoman said the offer's joint lead managers were pleased with the strong retail demand seen on both sides of the Tasman.
"Key elements that have resonated [include] the strength of the business positioning, high dividend yield, quality of management and familiarity of the brand."
Retail investors are, however, expected to face heavy scale-backs in their share applications.
Meanwhile, local market sources still had concerns about Tegel's outlook yesterday.
"There is good interest at the low end of the [price] range," said one investor, who requested anonymity. "People are really struggling with the higher end."
He said there were question marks around Tegel's growth story, which involves a push into new international markets, including South Korea and Japan.
A number of recent New Zealand sharemarket floats have performed poorly post-listing and the source said retail investors should "learn from some of the previous IPOs".
Listings backed by private equity investors have also been attracting scepticism following this year's collapse of electronics retailer Dick Smith, which listed on the ASX in 2013.
"There is certainly still a significant lingering distrust in markets of private equity and private equity sell-downs," said another market source, who also didn't want to be named.
He added, however, that "sufficient demand" existed for Tegel to get its deal over the line.
The offer will raise between $299.1 million and $344.4 million.
More than $130 million of the cash raised will be used to repay bank debt, while up to $163 million will repay shareholder debt.
The remaining $22.5 million to $25.3 million will cover IPO costs, including an $8 million bonus for senior management.
Affinity Equity Partners will sell around 30 per cent of its existing 87 per cent stake in Tegel through the deal.
Tegel has forecast net profit to rise from $10 million in the year to April 24, 2016, to $44 million in the following 12-month period, thanks largely to decreasing finance costs.
The deal is being managed by Deutsche Bank/Deutsche Craigs, Goldman Sachs and First NZ Capital.
