After a day with the younger leaders, Prime Minister Jacinda Ardern will tonight meet one of the most experienced and powerful - German's Chancellor Angela Merkel.
It will be one of Ardern's most interesting meetings because of the sway Merkel has in Europe and over international events - making her a potentially powerful ally on issues from the reform of the Security Council's veto power to free trade in the EU.
While Ardern may have some explaining to do about NZ First leader Winston Peters' sympathetic views toward Russia, Merkel has been a strong supporter for New Zealand's attempts to get a free trade agreement with the EU.
That is critical as New Zealand's traditional champion, the United Kingdom, prepares to leave the EU. However, Merkel is almost certainly in her final term as Chancellor and Ardern will want to make steps to ensure that goodwill is passed on.
Merkel is something of a role model for centre-left leaders.
