Christchurch, March 13 (TIWN) A year on from the Christchurch terror attack on two mosques that killed 51 people, New Zealand has "fundamentally changed", Prime Minister Jacinda Ardern said on Friday.

Fifty-one people died when a gunman attacked two mosques last March.

Hundreds of people from the mosques attended a joint prayer meeting at the Horncastle Arena in the city to mark the anniversary.

Although the anniversary is on Sunday, it was the mosques' Friday prayers that were targeted last year.

The arena is near the Al Noor mosque, where 43 people were killed. Eight were killed at the Linwood mosque.

A second larger event will be held on Sunday, also at the arena.
