US President Joe Biden has sent his "warmest regards" to Kiwis in a letter marking Waitangi Day.
Jacinda Ardern she said found the letter waiting for her after getting back from Waitangi on Saturday.
"Given it was intended for everyone, I thought I'd share it here!" the Prime Minister wrote on Instagram.
"Dear Prime Minister," Biden wrote in the letter.
"The American people join me in offering warmest regards to the people of New Zealand on the occasion of Waitangi Day on February 6."
Biden went on to say that New Zealand was one of the States' "closest friends and partners" and that the two countries shared an "unbreakable bond", ever since the first US consul was on hand to witness the signing of the Treaty of Waitangi in 1840.
"We have since partnered together to build the multilateral framework that benefits our nations as well as the global population. I look forward to strengthening the US-New Zealand relationship and cooperating to overcome the greatest challenges of our time," he wrote.
Biden also noted he had "fond memories" of a trip to New Zealand in 2016, where he experienced the country's "legendary reputation for friendliness and hospitality".
So far, Ardern's post sharing the message has received more than 40,000 likes.
"Diplomacy and respect at its best," commented one person.
"Thank goodness I can say I'm proud to be an American again," another person wrote.
