In Cambodia Destiny and Katrina will be working at The Grace Centre home for abandoned children where they will build a shower/toilet block.
"When we get there, we will paint and open these new facilities. We will also paint a Kiwiana mural for Child Rescue and teach the children games and waiata," says Katrina.
Child Rescue helps children from sex trafficking and sex exploitation.
The children were promised safe jobs in the city to help provide for impoverished families but instead they are forced into brothel work.
Since 2011 Child Rescue has rescued more than 2500 children.
After reintegration the girls receive followup care for two years.
The team of eight youths and two adults have been raising money for the trip.
