Jacinda Ardern catches up with leader 18,000km away to compare COVID-19 ideas

Danish Prime Minister Mette Frederiksen may be about 18,000km away from New Zealand, but Prime Minister Jacinda Ardern says we're "all in the same fight" against COVID-19. 

The two leaders have caught up on the phone to compare ideas about combating the coronavirus, a photo posted to Ardern's Instagram on Wednesday morning shows. 

"I've been asked a few times about whether world leaders are sharing ideas with one another right now - we are!" Ardern captioned the Instagram post, showing her in conversation with Denmark's 42-year-old leader. 

"There's not a lot of time, but this week I caught up with Mette Frederiksen the Prime Minister of Denmark who I met at the end of last year. We may be far away, but we're all in the same fight against COVID," Ardern said. 

Denmark, with a similar, slightly higher population to New Zealand of 5.6 million, has reported more than 6500 cases of COVID-19 and almost 300 deaths. Denmark, however, does not have New Zealand's advantage of being as isolated. 

But compared to other European countries, Denmark is considered to be doing well in the fight against COVID-19, as the second country in Europe to announce a lockdown before it even reported its first death. 

By comparison, Spain, Italy and France have each reported more than 100,000 COVID-19 cases, with each country recording more than 15,000 deaths so far. 

New Zealand has so far recorded nine deaths related to COVID-19, with the total number of cases reported now at 1366. 

Ardern said last week she has been in frequent contact with other world leaders, but said she spends the most time talking to Australian Prime Minister Scott Morrison and Canadian Prime Minister Justin Trudeau. 

Canada has so far reported more than 26,000 cases of the coronavirus and recorded almost 900 deaths, compared to Australia's 6400 cases and 61 deaths. 

Ardern said last week she caught up with Swedish Prime Minister Stefan Löfven, who decided not to implement a lockdown on the country, leaving bars, cafes and restaurants open to the public. 

Sweden has recorded more than 11,000 cases of COVID-19 and reported more than 1000 deaths, compared to its neighbour Norway - where a lockdown was implemented - which has recorded more than 6000 cases and 139 deaths. 

Ardern did not reveal the details of her conversation with Löfven at the time.
