While some critics may say the Reserve Bank should focus on inflation and interest rates, Orr said the bank had a strong vested interest in, and influence on, the long-term economic wellbeing of New Zealand.
"The long-term issues are critical to our task of maintaining low and stable consumer price inflation, promoting a sound and dynamic financial system, and meeting the currency needs of the public," he said.
While millions of people had been lifted out of poverty in the last couple of hundred years, there remained massive global challenges that were often resolved through financial crises, wars or civil unrest, or at the cost of someone else or something else, such as the environment, Orr said, singling out environmental degradation, mass urbanisation, ageing populations, mass migration and income and wealth inequalities as current challenges.
In New Zealand, challenges included our environmental impacts, migration and urbanisation, creaking infrastructure, a rapidly ageing population, over-exuberant house prices, low productivity growth and persistent and stubborn unemployment and low incomes, particularly among Pasifika and Māori, he said.
Still, capitalism could be improved, he said, noting the rapidly growing clusters of global capital concerned with better managing the failures that can arise from "short-termism".
"Hopefully, these efforts will, in part, head off the usual manner in which we 'reset the clock', through some kind of crisis or unrest," he said.
"Significant global firms, investors, regulators and representatives of civil society are banding together to work hard on resolving the perils of short-termism."
New Zealand had the opportunity to lead the globe in positive change if it became more long-term in its economic activity, Orr said.
While a small country, the world often looked to places such as New Zealand for leadership, he said.
"The great news is we are small, young of nation, lightly populated, green, kaitiaki [caretaking] of spirit, not dependent on the export of fossil fuels, and have a strong rule of law and sound moral compass," he said.
"Significant and bold leadership is in our grasp."
