There were no formal public events in Northland to mark the Christchurch mosque shootings, but flowers and "thinking of you" cards were left outside the Islamic centre in Whangārei.
Tuesday marked three years since Australian Brenton Tarrant killed 44 people at the Al Noor mosque during Friday prayers. He then drove to the Linwood mosque and killed seven more.
Last year the 30-year-old white supremacist pleaded guilty to 51 charges of murder, 40 charges of attempted murder and one of terrorism. Tarrant was sentenced to life in prison without the possibility of parole.
New Zealand quickly passed new laws after the attacks that banned the deadliest types of semiautomatic weapons.
A card left by Multicultural Whangārei outside the Whangarei Islamic centre on Tuesday, alongside a bunch of flowers, read: "Our hearts and prayers are with you today."
