New Zealand artists Hollie Smith and Te Karehana Gardiner-Toi (Teeks) have sung a moving rendition of How Great Thou Art in remembrance of the Christchurch terrorist attack victims.

Before a standing audience of thousands, the pair sang in remembrance of the 50 people who lost their lives in the shootings at two mosques on March 15.

The National Remembrance Service was held at North Hagley Park in Christchurch.
