We all like to think we've touched the lives of others in some way, but it's hard to go past Reverend Barbara Walker.
For two decades she delivered babies, helped to build hospitals and offered words of comfort to the sick, injured and scared, amid civil war and genocide.
Barb as she likes to be known, was born in Southland but her job as a crisis aid worker took her to Asia, Africa and the Middle East.
