Wellington: New Zealand Prime Minister Jacinda Ardern on Tuesday expressed concerns about the Australian-born terrorist Brenton Tarrant's plans to represent himself in future court hearings.

"I agree that is absolutely something that we need to acknowledge and do what we can to prevent the notoriety that this individual seeks. This could involve a conversation with the media," New Zealand Herald quoted Ardern as saying to reporters here.Asserting that the suspect was planning to "lift his own profile", the New Zealand premier remarked: "That's something that we can absolutely deny him. You won't hear me speak his name."
