Wellington: New Zealand Prime Minister Jacinda Ardern on Tuesday (July 16) joined international condemnation of US President Donald Trump's racist tweets about progressive Democrat congresswomen.

Ardern, the charismatic young leader who has been hailed as "the anti-Trump" by the US media, said she proudly celebrated her country's diversity.

"Usually, I don't get into other people's politics. But it will be clear to most people that I completely and utterly disagree with him," Ardern told Radio New Zealand.

"If you're not happy here, you can leave. This is about love for America, certain people hate our country," Donald Trump said in his tweet.

Ardern said New Zealanders welcomed diversity in the corridors of power.

"We take the view that our parliament should be a representative place. It should look and feel like New Zealand. It should have a range of different cultures and ethnicities," she said.

"And never should a judgement be made about the origin of anyone, and their right, therefore, to be in parliament as a representative," the New Zealand Prime Minister added.

British Prime Minister Theresa May and Canadian leader Justin Trudeau have also condemned the tweets, while Democratic presidential candidates have labelled Trump racist.

Ardern has not been shy about highlighting her differences with Trump in the past, advising him to send "sympathy and love to all Muslim communities" in the wake of the Christchurch-mosques massacre in March when a gunman killed 51 worshippers.

Shortly after Ardern's stunning election win in late 2017, Trump met her at a summit in Vietnam and joked she had "caused a lot of upset in her country".

"You know, no one marched when I was elected," she retorted, referring to the protests that followed Trump's victory in 2016.
