"He was taken straight to prison labour house to pay off his fine," Korea JoongAng Daily said.
Park said it was only when the Herald began publishing articles about construction plans by new owners for a former Daeju site that Korean media reported Huh's activities and raised questions about those and the huge tax bill.
"Who's Daeju, is he still making money? It snowballed from there into casinos and gambling and the luxury lifestyle and the sentence," Park said.
It was "regretful" that Huh faced "misfortunate issues in Korea" but that it was important to realise these were personal.
"They should not involve or interfere [with] any of the companies or businesses here in New Zealand. Also there are no legal obligations from New Zealand to be part in this matter," Park said.
KNC was developing two Auckland apartment projects which would be worth $61 million, creating 150 full-time construction jobs and residences for 500 people.
Park said Huh had been charged with not paying $17.3 million tax for which he had incurred a $27 million fine.
He said Huh had no shareholdings or directorships in any of the companies in New Zealand.
