High profile Australian broadcaster Andrew Bolt has accused New Zealand and its Government of "backstabbing" Australia, in a seven-minute live rant on television.
It comes after New Zealand was absent from the list of countries raising concern over the World Health Organisation (WHO) Covid-19 origin report.
The WHO released areport on Tuesday into the origins of the SARS-CoV-2 virus and its transmission within China, centred in Wuhan, before it spread globally.
In May last year, Prime Minister Jacinda Ardern said the Government supported calls to evaluate Covid-19's origins, but didn't want to see it turn into a witch hunt.
The virus has so far infected more than 128 million people worldwide and killing nearly 3 million.
"This is New Zealand sucking up to the Chinese dictatorship.
"May I ask what New Zealand has done while Australia is getting punished for standing up for freedom, which includes New Zealand's freedom? New Zealand sold us out."
Bolt said it's become part of a "shameful" pattern where New Zealand did little to confront China while Australia was punished by Beijing for calling it out over Covid-19, its actions in Hong Kong, and treatment of the Uighurs.

But just on Wednesday, Minister of Foreign Affairs Nanaia Mahuta shared concerns of electoral changes.
Aotearoa New Zealand 🇳🇿 is deeply concerned by China’s passing of electoral changes for #HongKong. Such changes do not keep faith with the Sino-British Joint Declaration & will further erode #HongKong’s democratic institutions and freedom of speech and association.
"Aotearoa New Zealand is deeply concerned by China's passing of electoral changes for #HongKong. Such changes do not keep faith with the Sino-British Joint Declaration & will further erode #HongKong's democratic institutions and freedom of speech and association," Mahuta tweeted.
Last month Ardern said the relationship between New Zealand and Australia remains strong despite concerns of friction between the transtasman countries.
She said the relationship between herself and Australian Prime Minister Scott Morrison is "excellent" and that they work frequently together.
