Prime Minister Jacinda Ardern is hoping for some "wins for New Zealand" at the Commonwealth Heads of Government Meeting this week.
The biennial summit meeting of the heads of government from all Commonwealth nations is being held in the United Kingdom and Ms Ardern and Foreign Minister Winston Peters are attending.
Ms Ardern released a video on Sunday about the meeting, saying it was a chance to talk about things that were important to small nations like New Zealand.
She mentioned inclusive growth and climate change as issues and the challenges of international security.
CHOGM gets under way on Monday (UK time). Prince Harry is opening the Commonwealth Youth Forum on the first day while UK Prime Minister Theresa May speaks at the opening of the business forum.
There has been speculation ahead of the meeting that the Commonwealth may become more important as the UK exits the EU.
Ms Ardern said she wanted to raise issues of interest to New Zealand and "hopefully we get some wins for New Zealand along the way as well".
