Prime Minister Jacinda Ardern has wrapped up talks with German Chancellor Angela Merkel in Berlin, the pair talking on topics from the missile attacks on Syria, the problems with Russia and Whauwhau the Kiwi Merkel had released on her visit to New Zealand a few years ago.

After the meeting, Merkel said the relationship was "truly excellent" and a free trade agreement between the EU and New Zealand would enhance that.

Merkel's opening statement appeared to allay concerns Ardern would be questioned about New Zealand's stance on the missile attacks on Syria - a case in which Ardern had taken a more moderate stance than Merkel and countries such as Canada and Australia.

Merkel said they had discussed Brexit,"how do we deal with Russia" and the unfolding situation in Syria. "We are very grateful NZ has taken a very clear stance on all these issues and I believe we will be able to continue our exchanges on security and defence issues."

In turn, Ardern appeared to slightly upgrade her stance on the missile strikes on Syria from "accepting" the need for them to "utterly accept."

Ardern said the use of chemical weapons was a case of "blatant breaches" of international law that could not go unchallenged and "we utterly accept" that was because of the inability of the Security Council to act.

She later denied there was a difference in language, saying it meant the same thing.

The two MMP leaders also spoke about coalitions and Merkel said she had learned something from Ardern - that a government could be set up with separate documents setting out the agreements with each party involved.

She said it was something she had not considered for Germany.

Both said they probably shared the same day to day issues of managing coalitions.

Merkel treated Ardern warmly.

Asked about their coalitions and how the meeting had gone, she answered the first but forgot the second.

Prompted about the second, Ardern had to translate: "they want to know if you found me likeable."

It prompted a 'mein Gott' from Merkel, before she said the meeting went well: "time flew and it was nice, it was very interesting and fun. So you can be proud of your Prime Minister. If you want to write this down for the New Zealand press. This will be the headline in the morning papers I trust."

However, one of the matters top of Merkel's mind appeared to have been the wellbeing of Whauwhau - a kiwi she released onto an island on her visit to New Zealand.

At the top of the press conference, Merkel reported "I learned Kiwi Whauwhau enjoys excellent health" and Ardern promised to send photos soon.

Ardern was greeted with military honours for the meeting at the Federal Chancellery in Berlin - a ceremony which is put on for every first visit by a leader.

Merkel and Ardern greeted each other very warmly and a smiling Merkel chatted happily as they walked into the Chancellery for a working lunch after the military guard.

The military honours are put on for the first visit of any leader.

Merkel has been a strong supporter of the free trade agreement between the EU and New Zealand and Ardern's visit is primarily for relationship building as Merkel is considered the most powerful person in Europe.

Germany New Zealand Chamber of Commerce CEO Monique Surges told Kate Hawkesby there's been a lot of positive press coverage about Ardern's visit.

"NZ has always had a very strong focal point for Germans, they've always had this fascination with NZ."
