The choir usually perform at least two concerts each year and have a long-standing dedication to encouraging young artists by inviting them to perform at their concerts.
Shaw, who is working towards a master of music at the University of Waikato, was also a student at Wanganui Opera Week this year.
"I met some of the choristers from the Male Choir and was invited to perform at this concert," she says.
"My parents live in Marton so I come to Whanganui fairly often but it is always nice to get the chance to perform here."
The choir were saddened by the death of their former musical director, Judy Barrett, early last year and have got used to working with current director Margaret Thompson who accompanied them on an Australian tour.
Abigail Livesay, who was both accompanist and director with the choir for a time, was replaced by Caitlin Arthur but she has returned to accompany Shaw for the Sunday concert.
