"New Zealand is committed to working together with NATO partners to contribute to collective security, such as through our support for Ukraine's self-defence," he said after attending the NATO Ministers of Foreign Affairs meeting in Brussels earlier this week.
He said the outcome of the war in Ukraine would have major impacts on global security, "and that is why New Zealand must be prepared to do its part."
New Zealand has been negotiating a new type of partnership with NATO as the alliance shifts all its partnership arrangements to a new model called an Individually Tailored Partnership Programme.
"We expect to conclude this partnership in the coming months, agreeing tangible areas of cooperation," Peters said.
Peters will travel to the United States and is expected to meet next week Secretary of State Antony Blinken and United Nations Secretary General Antonio Guterres to discuss major global and regional security challenges, his office said.
He will address the UN General Assembly on New Zealand's "deep concerns about the situation in Gaza" and return to New Zealand on April 14.
