Jacinda Ardern reveals more about phone call with Donald Trump

Incoming prime minister Jacinda Ardern has revealed a few more snippets about her calls with Donald Trump and Justin Trudeau.

Ardern said she spoke on the phone for five minutes on Monday with US President Trump.

"I was really interested to see how much the president had genuinely been interested our election," she told TVNZ on Wednesday.

There had been a lot of coverage in Washington and on the east coast, the president told her.

They also talked about their upcoming trip to Apec in Vietnam, but Ardern wasn't sure if they would formally meet there.

There appeared to be no repeat of the initial, heated phone call between the polarising Trump and Australian Prime Minister Malcolm Turnbull, during which they clashed over a refugee deal.

"It was a warm conversation," Ardern said.

"Regardless of the different views when they take on political issues, I will always advocate on New Zealand's behalf and that means a close and warm relationship with the United States."

Ardern, 37, had a longer Skype conversation with Canadian Prime Minister Trudeau on Tuesday.

Like Ardern, Trudeau, 45, is the second-youngest leader in his country's history.

They spoke about being leaders when you are "slightly in a different age cohort than some of our counterparts" and also Apec, the East Asia Forum and challenges around trade agreements, Ardern said.

Trudeau tweeted he was "eager to meet in person soon to keep building ties and trade between our countries".
