Hipkins yet to decide whether he will attend NATO meeting

Prime Minister Chris Hipkins has been invited to attend this year's NATO Leaders' Summit, as the military alliance looks to increase its engagement in the Pacific region.

NATO has invited its four Indo-Pacific partners (Australia, Japan, South Korea and New Zealand) to attend the event, due to be held in July.

Former prime minister Jacinda Ardern became the first New Zealand leader to address such an event when she attended last year's summit in Madrid.

Hipkins on Tuesday confirmed he had received the invitation but was yet to confirm whether he would visit Lithuania's capital Vilnius for the two-day conference in July.

"It's a big year domestically ... including the fact there's another event here in October that I have an interest in (the general election), so my international travel programme won't be massive," Hipkins said.

NATO plays an important part in world security, he said.

"We've remained, as I've always said, independent in our foreign policy and that will continue to be the case. But we will continue to work with like-minded countries.

"If you look at the situation in Ukraine, for example, we have a lot in common with members of NATO when it comes to our position on that particular conflict."

Hipkins said there were also some "strategically important" things for New Zealand to consider, including two "reasonably significant trade agreements" which the government was aiming to get across the line this year.

The invitation follows Foreign Minister Nanaia Mahuta's visit to Brussels last week, where she participated in a session of the NATO Foreign Ministers meeting.

Top NATO officials have also visited Wellington in recent weeks, prompting some experts to suggest New Zealand had formed a closer relationship with the military alliance.

Mahuta would only say the war in Ukraine had prompted more engagement with the likes of NATO.

"What we're seeing is New Zealand recognises the regional implications of a war in Ukraine, and what might happen in our own region," Mahuta said.

"We need to stay connected to members of the international community who are facing the immediate impacts of war in the region, and then outline what are the potential consequences for us here in our region, and that is why we remain engaged," she said.

"We've been quite consistent in terms of how we reflect our interests where we need to, when we need to, and we should do that.

"We should continue to assert our interests in whatever forum - whether it's ASEAN, or NATO, or, you know, in the Middle East - we should continue to assert and engage with regional architecture that help us say 'these are the things we're concerned about, these are the interests that are at the forefront of our mind' as we're impacted by these global events."

NATO's strategy for the next decade was set at last year's leaders' summit.

It included a commitment to strengthen ties with partners in the Indo-Pacific to tackle cross-regional challenges and shared security interests.

Hipkins also said the government was concerned about escalating tensions in the Taiwan Strait and continued to maintain its position that it would prefer a diplomatic solution.

China has accused the US of stoking tensions in the region by going against the One China policy, which claims the self-governing island as an integral part of mainland China.

Bejiing carried out aerial and naval blockade drills around Taiwan that ended yesterday, sparked by Taiwan President Tsai Ing-wen's meeting in Los Angeles with US House of Representatives Speaker Kevin McCarthy.

"If there's a role that we can play diplomatically, then that's something New Zealand will always do," Hipkins said.
