Jacinda Ardern has rubbed shoulders with several world leaders at the ASEAN Summit gala dinner while wearing their traditional delegates shirt for the first time.
Philippine President Rodrigo Duterte greeted Ms Ardern and other leaders one by one as they arrived at a convention centre in Manila for the glitzy event.
Donald Trump, Justin Trudeau and Malcolm Turnbull are among the leaders that posed for a group photo in their traditional shirts made from the husks of pineapples before everyone filed into dinner.
The summit focuses on matters of regional security, and the death penalty is also likely to be an issue, with Ms Ardern previously voicing objection to the Philippines' enforcement of the policy.
Ms Ardern has just wrapped up new negotiations for the Trans-Pacific Partnership (TPP) at the summit, where she and Trade Minister David Parker said a new, "better" deal has been agreed in principal for New Zealand.
She is also expected to continue pressuring the Australian government to accept New Zealand's offer of taking in Manus Island refugees, or finding some kind of solution to the problem.
New Zealand has offered to take 150 refugees following the closure of the Australian Government-run detention centre on the island last month, but the proposal was rejected.
