Christchurch's Mayor says she's proud at how unified the city has been in the year since the mosque shootings.

This Sunday marks the first anniversary of the mosque shootings.

A memorial honouring the 51 who died will be hosted in the city's Horncastle Arena.

Lianne Dalziel told Mike Hosking she's spent the past few days reminiscing.

"There has been much sadness and pain - but also a lot of compassion and love and it's been humbling to read and see it all."
