There's a risk New Zealand's focus on bilateral aid could destabilise international cooperation, the head of New Zealand's aid programme admits.
A majority of New Zealand's aid goes directly to projects in individual countries, rather than through international bodies such as the UN or the Global Fund.
The head of the development division at the Ministry of Foreign Affairs and Trade, Jonathan Kings, fronted a Parliamentary select committee reviewing the aid programme this week.
Green Party MP Golriz Gharaman asked him whether the bilateral approach risked undermining international cooperation on combatting climate change and other challenges.
Mr Kings said more could be done.
"Yes, it is a risk. In our budget bids, when we got the new money, we said that one of our priorities should be the multilateral system, because we felt that relatively we're underinvested in the multilateral system."
However, Mr Kings said New Zealand remained a core funder of the multilateral system.
He also hit back at suggestions the ministry lacked development expertise.
Several submissions claimed the ministry lacked expertise in development aid.
A large and controversial restructure nearly a decade ago saw New Zealand's aid agency folded into the ministry, prompting many redundancies.
But Mr Kings said the ministry was stacked with a large and diverse range of people with wide-ranging expertise.
