The man accused of carrying out the Christchurch terror attack is to face a total of 50 murder charges.
The 28-year-old Australian will also face 39 charges of attempted murder when he appears in court via video link on Friday.
He was originally charged with a single count of murder as a holding measure.
The massacre he carried out at two mosques in the New Zealand city on March 15th was the worst lone-gunman shooting in the country’s history.
He broadcast the attack live on Facebook.
Christchurch terror attacks — further charges laid.
Police can now confirm the man arrested in relation to the Christchurch terror attacks will face 50 Murder and 39 Attempted Murder charges when he appears in the High Court in Christchurch on Friday 5 April.— New Zealand Police (@nzpolice) April 4, 2019
Police said they are still considering whether to lay other charges against him.
The terror attacks at the al Noor mosque and the Linwood Islamic Centre led to a major overhaul of the gun laws in New Zealand.
The new laws include an effective ban on assault weapons and semi-automatic rifles.
Meanwhile, tens of thousands of people gathered at memorial services around the country to remember the victims.
Muslim leaders and representatives from 59 countries were among those in attendance at Christchurch's Hagley Park.
Musician Cat Stevens - also known as Yusuf Islam - performed at the ceremony.
The country’s Prime Minister Jacinda Ardern warned that violence and terrorism require a collective response from the global community.
“We cannot confront these issues alone, none of us can,” she said.
"But the answer to them lies in a simple concept that is not bound by domestic borders, that isn’t based on ethnicity, power base or even forms of governance.
"The answer lies in our humanity."
The youngest person murdered on the day was just three-years-old, while the eldest was 71.
