Kiingi Tūheitia has meet with Prime Minister Christopher Luxon before a national hui is held later this week.
The private meeting between Luxon and the Kīngitanga took place before a nationwide hui on Saturday.
The Prime Minister's Office confirmed the meeting in a statement to media.
"Today Prime Minister Christopher Luxon and Minister for Māori Development Tama Potaka met with Kīngi Tūheitia at Ngaruawahia," a spokesperson told Newshub.
"The meeting had been planned since last year and was an opportunity to further build on the relationship they have established in the last two years."
In December, Kiingi Tūheitia Potatau Te Wherowhero VII issued a issued a royal proclamation, Te Paki o Matariki, to "unify the nation" in the face of the new Government's Treaty policies.
It came a day after thousands of people around New Zealand protested against the new government's policies on co-governance and the Treaty.
"Kiingi Tuheitia received a very clear message from many Rangatira across the motu last weekend, after celebrating the 165th anniversary of the birth of the Kiingitanga movement. Therefore, Te Paki o Matariki (a Royal Proclamation) has been issued calling for the national hui," a statement from the Kīngitanga said.
The proclamation said many Māori "are concerned about the plans of the new Coalition Government".
"Our most effective response will come from working together. After consulting with many Rangatira from across the motu, the Kiingitanga has decided to convene a National Hui. This Hui will provide a space for koorero and waananga guided by our tikanga," it said.
"It will be a platform not only for our voices to be heard but also our rangatahi to have a say in shaping a united way forward. It will also serve as an opportunity for us to assert our Mana Motuhake, as we make decisions for our future."
The hui is expected to be held at Tūrangawaewae Marae on January 20.
