Yesterday's refugee quota announcement, paired with the ban on oil and gas exploration announced in April, will give Jacinda Ardern more credibility and a stronger hand while attending the United Nations General Assembly in New York next week, she said.
"Of course, doing your part adds to your weight that you're able to bring to the debate," she told 1 NEWS political editor Jessica Mutch McKay in a one-on-one interview today.
During what will be her first UN General Assembly meeting, the Prime Minister has been chosen to deliver a number of keynote addresses, including for the opening of UN Climate Week. In devising her strategy for the week, Ms Ardern said she turned to our past.
"Nuclear proliferation is a great example," she said. "New Zealand's always been looked to as an exemplar because we've always taken a firm stance and we've acted on it. On climate change I hope we'll be seen in the same way. But yes, the refugee quote is about us doing our bit in response to a humanitarian crisis."
Ms Ardern announced yesterday that starting in 2020 New Zealand will help resettle 1500 refugees here per year, 500 more than the current amount and double what it will have been just five years earlier. The move has been hailed by the Red Cross and other humanitarian groups.
Also during her week in New York, Ms Ardern will be appearing on the Today Show, The Late Show with Stephen Colbert and will sit down for an interview with CNN's Christiane Amanpour.
"It's hard for me really to know whether I'm getting any more or any less (attention) than other New Zealand leaders," she said as Mutch McKay pointed out they're pretty "big gigs".
"They are (big) but I'll be doing my best to make sure that they are in the best interest of New Zealanders as well," she said. "That I use those opportunities to promote New Zealand -- in some cases, as a destination, on others just promote our stance in issues of international significance.
"For me, it's about making sure I'm the best representative for New Zealand I can be while abroad."
