Major Trump announcement could involve New Zealand

The White House is expected to make a major announcement that could involve New Zealand. 

Foreign Minister Winston Peters has been given a high level briefing from Secretary of State Rex Tillerson about moves the United States wants to make in the Asia Pacific, but he's been sworn to secrecy. 

"Tillerson wants New Zealand to be engaged in something and you will learn more in the coming days," says Mr Peters.

The pair met at the same time President Donald Trump sent a cryptic tweet promising a major statement. He's now returned to Washington, but it's unclear when he'll make the announcement.

Neither Mr Peters nor Ms Ardern were prepared to comment on whether the briefing was linked to the statement.

"One would be unwise to predict the nature of any of President Trump's tweets," says Ms Ardern.

It's understood Mr Peters will at some point be taken into North Korea acting on behalf of the West as a diplomatic liaison, and not for the first time.

The Deputy Prime Minister is one of only a handful of Western leaders to have visited the insular dictatorship of North Korea, back in 2007.

It's now been floated that he travel with a Kapa Haka group. His MP Shane Jones says Māori culture has some place in our international diplomacy 

Ms Ardern and Mr Peters are now en route back to the Beehive after what has been an intense week on the international stage. They'll face more questions as soon as they get off the plane about just what the United States wants from us.
