Survivors have marched to Parliament ahead of the release of a report from one of New Zealand’s largest and most complex inquiries.

The final report from the long-running Abuse in Care Royal Commission of Inquiry will be presented to Parliament - and released publicly - this afternoon, more than five years after the terms of reference were first announced.

The inquiry was established in 2018 to investigate the abuse and neglect of children, young people and adults in state and faith-based care from 1950 to 1999.

The inquiry - the largest and most complex in New Zealand’s history - included accounts from almost 3000 survivors, analysed more than 1.1 million documents and held more than 130 days of public hearings.

Over the years, the inquiry has heard from a long line of survivors, government heads, and church leaders. From Dilworth School and Lake Alice Psychiatric Hospital to the Catholic Church and Gloriavale, it has seen and heard it all.

Common themes have included significant sexual, verbal, and physical violence, over-medicalisation, isolation, and unsanitary conditions.

It’s believed more than 250,000 people have been abused in state and faith-based care in New Zealand.

Survivors gathered in Wellington’s Frank Kitts Park at lunch time before marching along the waterfront and up to Parliament.

They were carrying a long banner full of ribbons with survivors’ names on them, representing the thousands of children who have suffered abuse in state and faith-based care.

The hīkoi was greeted with a traditional cultural welcome on arrival at Parliament. A number of people were visibly upset, crying and embracing each other on Parliament’s grounds.

Those holding the banner could be heard singing “This little light of mine”. Others could be seen holding framed photographs of their loved ones.

Most of the gathered crowd has now entered Parliament ahead of the final report’s official release.

On Monday, Prime Minister Christopher Luxon said what he had read of the report so far was “horrific and harrowing”. The report was 3000 pages long and weighed 14kg.

“This is a shameful part of our history. There are 3000 survivors who have actually contributed and had the bravery and courage to make their contributions to that,” he said.

“I want them to be heard and I want them to know on Wednesday that they are being heard.”

Luxon said he would deliver a formal apology to those who experienced state and faith-based care on November 12 at Parliament.
