Four years ago, the bodies of 12 British soldiers killed during the Battle of Ruapekapeka of 1846, were discovered near the site of the fighting.
On Wednesday, 175 years after their deaths, Prime Minister Jacinda Ardern and British representatives visited the site to remember their place in New Zealand's wartime history.
Ms Ardern, wearing a korowai or Maori cloak, joined Governor-General Patsy Reddy and British High Commissioner Laura Clarke at a dedication ceremony to unveil a memorial stone at the site.
"Some of the stories of Ruapekapeka have become legendary," Ms Ardern said.
"Of children inside the pa (settlement) defusing enemy shells before they could detonate, of the abandonment of the pas a trap for attacking forces.
"And of this remarkable and masterful structure that was finally set ablaze; the smoke and glow seen for miles around."
Hundreds, including descendants of chiefs involved in the battle, were present.
The battle at Te Ruapekapeka Pa, which occured on 10 and 11 January 1846, is part of the Northern or Flagstaff War in which British forces subdued a Maori rebellion.
Fighting between crown forces and Maori, now remembered as the New Zealand Wars, would continue for decades.
It is one of many episodes to be taught to New Zealand children from next year as part of a government pledge to finally revive forgotten parts of Kiwi history within the curriculum.
"There can be a tendency in New Zealand to underplay our history, to say ours did not happen on the scale of other countries around the world and that somehow scale has some bearing on significance," Ms Ardern said.
"That view is wrong ... Let us teach it. Let us learn it and let us remember it."
