A mass candle lighting will be held at the Glen Logie Rose Garden on Anzac Parade to commemorate children who have died.
The event, which will take place on Sunday, December 9, is held annually and is part of the 22nd Worldwide Candle Lighting.
The organisers, Whanganui Compassionate Friends, said New Zealand will start the candle lighting.
"A virtual 24-hour wave of light will move from time zone to time zone," they said
"Hundreds of formal candle lighting events are held and thousands of informal candle lightings are conducted in homes as families gather in quiet remembrance of children who have died, but will never be forgotten."
