The British government on Wednesday expressed “regret” that British explorers killed some of the first indigenous Maori they met 250 years ago but stopped short of issuing a full apology.

British High Commissioner Laura Clarke met Maori tribal leaders in the town of Gisborne as New Zealand marked the anniversary of the arrival of explorer Captain James Cook and his crew on board the Endeavour in 1769.

Clarke’s words held historical significance but fell short of the full apology that some had sought.

Shortly after the arrival of Cook and his crew, the group encountered armed Maori and believed they were under attack. Many scholars now believe the Maori were probably only issuing a ceremonial challenge.

The sailors shot and killed an important leader, Te Maro, and over the following days killed eight more Maori before a Tahitian priest managed to mediate between the sides.

The British High Commission said the exact wording of Clarke’s speech to Maori leaders would remain private, but that she would acknowledge the pain of those first encounters and extend her sympathy to the descendants of those killed.

Britain has also been returning some historic artefacts taken by Cook’s crew, including canoe paddles.

In a Facebook video, the Maori “iwi” or tribe Rongowhakaata described that first encounter in blunt terms: “After only being here for two hours, Cook and his crew had trespassed, terrorised, killed and stolen from us,” a narrator says.

The high commission was careful to point out that Wednesday’s expression of regret came from the British government and not from the British monarch, Queen Elizabeth II.

Maori are involved in a decades-long legal process seeking redress for historic wrongs under New Zealand’s founding document, the Treaty of Waitangi.

That 1840 document was signed on the British side by emissaries of Queen Victoria. Dozens of tribes have made settlements worth billions of dollars under the treaty’s provisions.

New Zealand’s Race Relations Commissioner and former Gisborne Mayor Meng Foon said Clarke’s words were another part of the reconcilliation and relationship-building process.

He said that as Gisborne mayor he had invited the British royal family to come to Wednesday’s event but had received no response.

He said he would like to have descendants of Queen Victoria meet descendants of the Maori who were killed and offer them a full apology.

“It’s not the end of the story,” he said of Clarke’s speech. “I believe future generations will demand an apology.”
