Prime Minister Jacinda Ardern says she looks forward to developing even closer relations with the incoming Biden administration.
She has congratulated president-elect Joe Biden and incoming vice-president Kamala Harris on their victory in the US Presidential election.
Ardern said the two countries will continue to work with each other, notably in the Pacific, and Biden has shown shared interest in addressing Covid-19 and climate change.
"New Zealand will continue to work side-by-side with the United States on the issues that matter to both of us, including the prosperity, security, and sustainability in the Indo-Pacific and Pacific Island regions," Ardern said in a statement.
"The campaign by the President-elect has also shown the shared interests we have in addressing global challenges like Covid-19 and climate change.
"There are many challenges in front of the international community right now, the message of unity from Joe Biden positions us well to take those challenges on."
Biden visited New Zealand in 2016 as vice-president under Barack Obama, with Ardern saying he was a close friend of New Zealand's.
