Ms Ardern said spending time with the US Vice President will be a good chance to raise questions about aluminium and steel tariffs that the US has placed on New Zealand and other countries.
"It's a great opportunity for me to raise issues that New Zealanders are focused on," she said, "of course, aluminium and steel tariffs".
Ms Ardern will also be meeting with the Australian Prime Minister, Scott Morrison, for the first time. She said she would raise the deportation of Kiwis at the meeting.
"Some of our concerns are around the application of their deportation policy. They're familiar with that, but it'll just be another conversation," Ms Ardern said.
It was this time last year when Ms Ardern lashed out at Australia, then under Malcolm Turnbull's leadership, over its treatment of Nauru refugees.
