Hannah Simpson, 18, and Sophie Squires, 17, travelled to Samoa on July 2 as part of a New Zealand church programme, Word of Life.
As part of the programme the pair took part in life courses and performed to audiences in schools, churches and a prison.
It was the first time the pair had ever travelled outside New Zealand.
Hannah said although they were joined by 44 other people it was still a nerve-racking experience.
"I am not an upfront person. It was difficult to perform in front of people."
She wasn't in it for the performances, she said.
