Prime Minister Chris Hipkins has been invited to the NATO Leaders' Summit in Lithuania, but is yet to decide if he will attend.
Former Prime Minister Jacinda Ardern took part in last year's event, becoming the first New Zealand leader to address the summit.
NATO has invited its Indo-Pacific partners - Australia, Japan, South Korea and New Zealand, to attend the event in July.
It follows two visits to New Zealand by NATO officials in recent weeks.
Also, Foreign Minister Nanaia Mahuta last week attended a NATO Foreign Ministers Meeting in Brussels where she was quizzed on Aotearoa's military alliance.
She also made comments on how Russia's invasion of Ukraine had changed the global landscape.
