New Zealanders are remembering the deadliest-ever attack on their shores. Fifty-one people died when a gunman opened fire on two mosques in Christchurch on 15 March, 2019.

Crowds were seen on Friday paying their respects to the victims.

Authorities have changed the country's gun laws since the attack. They've created a registry for monitoring sales, and imposed a ban on semi-automatic rifles.

Prime Minister Christopher Luxon says the government will continue to review the measures.
