PM calls for civil debate as government faces backlash over efforts to roll back policies to support Maori community.

New Zealand’s Deputy Prime Minister David Seymour has rejected criticism of his claims that colonisation was positive for the country’s Indigenous Maori population.

Dozens of people started booing and shouting when Seymour stood on Friday to offer a prayer during a dawn service at the Waitangi Treaty Grounds, where New Zealand’s founding document was signed in 1840 by representatives of the British Crown and more than 500 Maori Indigenous chiefs, setting out how the two sides would govern the country.

Seymour made his controversial comments that colonisation had been an overall positive experience for Indigenous people on Thursday during a speech to mark national Waitangi Day, an annual political gathering that gives Indigenous tribes a chance to air grievances.

“I’m always amazed by the myopic drone that colonisation and everything that’s happened in our country was all bad,” said Seymour, who is leader of the right-wing ACT Party and a member of the Maori community.

“The truth is that very few things are completely bad,” Seymour had said, according to local online news site Stuff.

Describing his hecklers on Friday as “a couple of muppets shouting in the dark”, Seymour said the “silent majority up and down this country are getting a little tired of some of these antics”.

Following Seymour’s prayer on Friday, left-wing Labour Party leader Chris Hipkins was also loudly jeered by those in attendance.

On Thursday, Indigenous leader Eru Kapa-Kingi told parliamentarians “this government has stabbed us in the front,” and the previous Labour government had “stabbed us in the back”.

Seymour’s government has been accused of seeking to wind back special rights given to the country’s 900,000-strong Maori population, who were dispossessed of their land during British colonisation and remain far more likely to die early, live in poverty or be imprisoned compared with the country’s non- Indigenous population.

Controversial legislation that was tabled last year seeking to reinterpret the treaty’s principles and roll back policies designed to address inequalities experienced by Indigenous people led to protests and failed after two of the three governing parties did not vote for it.

Speaking on Friday, New Zealand Prime Minister Christopher Luxon called for national unity and for steps to address challenges faced by the Maori community.

Luxon also said the national debate over the legacy of British colonisation should remain civil.

“We don’t settle our differences through violence. We do not turn on each other; we turn towards the conversation. We work through our differences,” Luxon said in a social media post.

Denial about the destructive legacy of colonialism and its connection to contemporary challenges faced by Indigenous communities remains a frequent subject of contentious debate in former colonies around the world, including Australia and New Zealand.
