He said New Zealand was seen as "clean, green and authentic".
"I think these are very relevant traits in many countries outside New Zealand where you don't have the same green spaces, the same emphasis on health ... cleanliness. It is meaningful to many Asians," he said.
"You're seeing a lot of Asian, particularly Chinese and Southeast Asian investment, looking at many sectors ... not only on the food side."
Gokongwei said the growing middle class in Southeast Asia were looking for high-quality food.
"Nobody can recreate a Griffin's [product]. Nobody can recreate 150 years of history and heritage," he said.
Griffin's biscuits were being launched in Singapore and Hong Kong, and by April would be rolled out across Southeast Asia.
Gokongwei said biscuits were popular in Southeast Asia, but Griffin's Toffee Pops and other chocolate biscuits were different to other products in the market.
"We expect Cookie Bear and a lot of the Griffin's products to be popular. Pure chocolate [in Griffin's biscuits] is a really unique offering. [Consumers in Southeast Asia] will look forward to trying that."
Griffin's chief executive Alison Barrass said since Universal Robina Corporation bought the company she and other employees had learnt about the culture of the Philippines.
"We're delighted to have an owner that's interested in growth ... but also provides a platform in Southeast Asia," Barrass said.
"It's put us in a very competitive position in that market very quickly. I think we couldn't have been more fortunate in terms of the ownership model."
