New Zealand is contributing $200,000 dollars to help monitor North Korea's nuclear programme.
Foreign Minister Winston Peters said the money would assist the Internation Atomic Energy Agency (IAEA) in carrying out its work.
"Peace on the Korean Peninsula cannot be achieved without complete, verifiable and irreversible denuclearisation," Mr Peters said.
"We want to make an early contribution to assist the IAEA in its current monitoring efforts and further hope that its inspectors are soon able to return to North Korea."
North Korea has said it will dismantle its nuclear test site within two weeks and is inviting international journalists to cover the event.
Its announcement came as North Korean chairman Kim Jong-Un prepared to meet the United States president Donald Trump in Singapore on 12 June.
Mr Peters said he spoke to his South Korean counterpart foreign minister Kang Kyung-wha today and reiterated to her that New Zealand will do all it can to support the peace process.
