The main suspect in the mosque shootings that killed 49 people in New Zealand on Friday has appeared in court on a single murder charge.

Australian Brenton Tarrant, 28, appeared in the dock in a white prison shirt and handcuffs. Further charges are expected to be made against him.

PM Jacinda Ardern said Mr Tarrant had five guns and a firearms licence, adding: “Our gun laws will change.”

Two others are in custody. None of those detained had a criminal record.

Mr Tarrant was remanded in custody without plea and is due appear in court again on 5 April.

Speaking at a news conference on Saturday, Ms Ardern said that the guns used by the attacker appeared to have been modified, and that the suspect’s car was full of weapons, suggesting “his intention to continue with his attack”.
