New Zealand Prime Minister Christopher Luxon apologized and promised reforms on Wednesday after a public inquiry found some 200,000 children, young people and vulnerable adults were abused in state and religious care over the last 70 years.

Nearly one in three children and vulnerable adults in care from 1950 to 2019 experienced some form of abuse, the report found, a finding that could leave the government facing billions of dollars in fresh compensation claims.

"This is a dark and sorrowful day in New Zealand's history as a society and as a state, we should have done better, and I am determined that we will do so," Luxon told a news conference.
