The 2016 Caritas Challenge for schools and youth groups is focussed on Cambodia, where many people face social injustice.
The challenge runs from April 1 to May 15.
The annual event in New Zealand aims at demonstrating solidarity with those living with poverty or injustice.
The challenge activities and experiences come under the headings “Move It”, “Live It”, “Sweat It” and “Stop It”.
Social injustices faced by many Cambodians include loss of land, the effects of climate change, human rights breaches and economic instability.
