"I think we're at the beginning of a new wave of trying to do things in the world and how businesses and entrepreneurs see the purpose of their organisations, and moving that from a purely financial to a much more socially or environmentally aware viewpoint," he said.
The new mindset would co-exist alongside traditional models of philanthropy, he said.
"We are also entering a renaissance of philanthropy with things like the Givealittle pledges, with more and more billionaires planning to give away half or more of their wealth, and a really fast-rising proportion of people starting to give significantly when they are very young."
Holland Becket partner Bill Holland, who chairs Community Foundations of New Zealand, attended the private dinner. He said the interesting part of the concept was about building the concept of philanthropy into a business from the start.
"It's not just a matter of people being successful and then deciding to be philanthropic," he said.
"The philanthropic side is incorporated in the business plan and it's quite interesting how that in itself can help make the business successful ... there's no question people are looking at the bigger picture. Environmental and sustainability concerns are important not only to business, but to their customers."
How business can give back to society
A private dinner brought Derek Handley together with some 20 Tauranga leaders in business excellence, academia, entrepreneurship, philanthropy, iwi fund management, early-stage investment, government and social enterprise.
It was hosted by Nicki Wilkins, general manager of the Acorn Foundation, and her lawyer husband Marcus, and arranged by Tina Jennen, who works with Enterprise Angels and local entrepreneurs.
The Acorn Foundation encourages people to consider leaving a gift either in their will or during their lifetime to benefit the local community and Ms Wilkins said the dinner provided an opportunity to hear more about what was happening in the business sector in terms of philanthropy. She is a board member of Community Foundations of New Zealand.
"The desire for people to give is growing significantly," she said. "I can see real benefits in Derek's desire to help people in business to give in a way they know they are truly making a difference."
Tina Jennen said Tauranga had the capability to become a national - and global - leader in the new and more socially responsible way of doing business.
"When you bring disparate people together a powerful cross-pollination of ideas can occur," she said. "We wanted a diverse group of key community leaders to hear Derek's plans so we can get ready to take action."
Derek Handley said the dinner had been a great opportunity to have more in-depth discussions.
"As small as New Zealand is, you don't get a chance to meet these people that often," he said. "It's fascinating what's going on here in Tauranga and it was really interesting and inspiring for me."
Tauranga was also beautiful, said Mr Handley, who stayed on for the weekend. He noted one of the roles of business and entrepreneurship in society was to enable people to have a fulfilling balance of holistic lifestyle for people. "In a city like this you can almost feel it being 21st century holistic living, but able to build interesting ventures that mean something. That's a great place to be."
