Supreme Court Justice Sir William Young will chair the Royal Commission of Inquiry into the Christchurch terror attack.
Prime Minister Jacinda Ardern made the announcement on Monday, saying the inquiry will start considering evidence from May 13 and report back by December 10.
The Commission will have a budget of $8.2 million, and will look at areas such as the alleged shooter's use of social media, his arrival and residence in New Zealand, and look at how agencies responded.

"The Government will ensure no stone is left unturned as we examine as quickly as possible how the March 15 attack happened, what could have been done to stop it and how we can keep New Zealanders safe," Ardern said.
"Justice Young, who is a sitting Judge of the Supreme Court of New Zealand – New Zealand's highest court – has the extensive experience and skills required to lead the Inquiry.
"I am confident that in his nearly nine years as a judge on our highest bench, Justice Young has the judgement, clarity and care to do the job, with a sound understanding of intelligence issues and experience working in the public eye."
Justice William Young was appointed a Queen’s Counsel in 1991, to the High Court in 1997, and to the Court of Appeal in January 2004. He became President of the Court of Appeal in February 2006.
Justice Young was appointed a Judge of the Supreme Court with effect from 1 July 2010.
