"We are very pleased that the Government continues to uphold Waitangi and what it stands for as an essential part of our national identity," he said.
"It is very important that we continue to work together on our mission to illustrate the promise of Waitangi to all New Zealanders, and indeed to the world. This allocation will enable us to do that."
Chief executive Greg McManus said New Zealanders had been flocking to Waitangi over the past year, with domestic visitor numbers since the borders closed exceeding all expectations.
"It is fantastic to see so many Kiwi families coming to Waitangi to engage in a conversation about our shared histories," he said.
"The budget allocation will enable us to keep the doors open, and continue to provide the outstanding visitor experience Waitangi is renowned for."
