RNZ can reveal New Zealand's foreign affairs ministry granted export permits for military equipment sent to Saudi Arabia's forces in 2016 and 2018.
It comes amid a government review into export controls following revelations Air New Zealand's gas turbines' unit did repair work for the Saudi Navy.
The Green Party says the export permits could make the government liable for war crimes, and they want regulations to be tightened up.
Mackenzie Smith reports.
In a statement foreign affairs minister Nanaia Mahuta said: "This export control case precedes my time as Foreign Minister and indeed was initially approved in 2016 under the previous Government.
"We made it clear this week we consider it unacceptable for entities connected to the New Zealand Government to be exporting military equipment to Saudi Arabia.
"This week the Government asked MFAT for further information about how it handles applications for military exports to Saudi Arabia to ensure New Zealand's approach to export controls is fit for purpose."
