New Zealand Finance Minister Bill English says his country has been given a unique opportunity to rub shoulders with the decision makers of the world's largest economies.
Earlier this month, Australian Prime Minister Tony Abbott extended an invitation to NZ to attend this year's series of Group of 20 meetings in Australia, dubbing it the G21.
Mr English was in Sydney this weekend for the first gathering of the world's largest developed and developing economies under Australia's 2014 presidency of the forum.
"We've been treated very well," Mr English told AAP on Sunday.
"But we understand there are 20 very large economies here, and they do want to have their say. So we don't get in their way."
Mr English said it had been a unique opportunity to understand what those countries were thinking and the likely decisions that would affect NZ.
"These are the people who make the waves that wash up on our shores," he said.
NZ businesses were also invited to join B20 discussions - the business arm of the G20 - and an Australasian business week would be held around the middle of the year.
Mr English said NZ businesses would be able to tout their ventures and attract investment, a lot of which comes from Australia.
"We would like to see more of it, because it will do well," he said.
Conversely, the minister wants to see more NZ business investment in Australia, after flat-lining for the past decade.
"It should be better because this is our closest, nearest and most manageable market," he said.
The NZ economy is enjoying a marked upturn, buoyed by Asian demand for its dairy products.
That demand looked "pretty solid" and dismissed suggestions NZ had become overly reliant on it.
"We are much less reliant on milk powder to China than Australia is on iron ore to China," Mr English said.
The minister said there were a range of other growing markets across the Asia-Pacific, like Indonesia and Vietnam.
Chinese demand was also gradually broadening to other products within the diary spectrum, while interest in NZ manufacturing service industries was growing.
"We're not quite so concerned about diversifying," Mr English said.
