Prime Minister Christopher Luxon says he will travel to Fiji and Niue next week in bid to help form "deeper and more comprehensive relationships" in the Pacific.
In a statement on Sunday, Luxon said he would be discussing New Zealand and Niue's "mutual expectations and priorities" with Premier Dalton Tagelagi.
Luxon would also discuss navigating "the increasingly choppy geostrategic waters ahead" with Fiji Prime Minister Sitiveni Rabuka, he said.
"The partnership between our two countries is broader than most New Zealanders are aware of, from our close security cooperation to our business links and - of course - our shared love of rugby," Luxon said.
On the trip to Fiji, Luxon's office said there would be a "significant trade and economic focus".
"Fiji is our biggest trading partner amongst Pacific islands countries and there is plenty of scope to leverage even more economic opportunities for Kiwi and Fijian businesses," the Prime Minister said.
Luxon was due to leave on Tuesday and return on Friday.
