The Royal Commission into the attack on the Christchurch Mosques will get down to business in the next few days.
A second and final commissioner has been announced to join commission chair Sir William Young. The Supreme Court judge will be joined by former diplomat Jacqui Caine - a career diplomat, a former ambassador to Chile and most recently special projects director for Ngāi Tahu in Christchurch.
They start work considering evidence next week.
Prime Minister Jacinda Ardern says the Government's confident the royal commission now has the right people in place to find out what happened leading up to the mosques massacre on March 15, and what could have been done to stop it.

Fifty-one people were shot dead and dozens injured in the massacre.
"The commission's findings will help to ensure such an attack never happens here again," said Ardern.
It's expected to report back by December 10.
