Yesterday's powhiri was calm and peaceful, watched by a crowd of about 150.
Ardern said the government had not come to Waitangi as ceremonial guests - they had come to Northland for five days because there was work to be done.
She is right.
Northland needs to work closely with the Government on issues like employment and education which can help appease the region's poverty and health challenges.
And somewhere within the five days of mahi, the treaty settlement process will have been discussed.
Many eyes are on Andrew Little - possibly one of the better qualified Treaty Settlement ministers New Zealand has had.
If Little brings Ngapuhi to, or even closer to settlement in the next three years, it will be because Ngapuhi has also done their own work internally, settled differences, and agreed to move on for the betterment of the tribe.
In which case, when February 2019 rolls around, Ardern will no doubt be expected to explain what she has done for Maori.
She will also be entitled to ask politely, perhaps quietly, of Ngapuhi, "what have you done to help yourselves?".
