Millennials - the generation born between 1980 and 2000 - were increasingly "choosing purpose over pay cheque" when looking for work, said Ryan, who won the Young New Zealander of the Year award in 2015.
"A pay cheque's still important - you have to pay the bills, you have to pay rent, you have to buy food. But being able to put energy, time and talent into things that will actually make a real difference is really important [to millennials].
"Millennials want to know how they can drive change in the organisation they work for to create change and better outcomes for society and the environment, not just day-to-day business as usual."
A recent survey Inspiring Stories conducted ahead of its annual conference for millennials, Festival for the Future, found the issues Kiwi young people were most concerned about were child poverty and mental and physical health.
Other issues that consistently came up were biodiversity, accessibility and affordability of housing and millennials' voices being represented when it comes to decision-making for the future.

Ryan said the success of Eat My Lunch, which donates a lunch to a Kiwi kid in poverty each time someone orders lunch for themselves, showed tackling child poverty was a priority for consumers.
It was a good example of how a business could change society for the better.
Just under half of the more than 10,000 participants of Deloitte's annual global millennial survey released last month said they believed businesses acted ethically. Of the 200 Kiwis spoken to that figure was 45 per cent.
Deloitte New Zealand director Lauren Foster said the results should be a wake-up call to business leaders.
Millennials currently make up more than a third of New Zealand's working population. By 2020 they will outnumber both baby boomers and Generation X.
Wellington startup Summer of Tech has been helping university graduates find internships in the technology industry for more than a decade.
Its chief executive Ruth McDavitt said although some startups and medium-sized businesses, like Xero and TradeMe, were keen to hire millennials, other companies snubbed young people, favouring more senior candidates.
"I think there's a lot of focus on hiring skilled and experienced older people. But we're never going to get future seniors if we don't employ juniors.
"We're losing talent overseas by not having entry-level jobs available. There's more people graduating and coming through courses than there are opportunities. Last year we had 2000 candidates looking for internships and we placed 220 of them into jobs."
In her experience, most millennials were motivated at work when they felt passionate about their job and felt like they had a purpose.
"When you're hiring millennials make sure that you're really clear about what your business goals are and they can align their values and understand that they will be making an impact," said McDavitt.
