Charge Audiologist Tamanna Khurana spent three days in Apia, Samoa at the end of July, seeing 180 people in the short amount of time.
"Every day there were lines of people waiting outside. Some of them had woken up really early in the morning, some had even travelled from another island," she said.
Six New Zealanders went over to help Samoans with hearing tests, fitting hearing aids and performing ear suctions.
