Angus' 1951 work was painted with oils while Rose has used acrylics and added her own symbolism.
She has depicted herself wearing the scarf that symbolises her Scouts New Zealand membership and while the Angus painting depicted a white lotus flower, Hird's one features a red rose.
"Obviously it's my name and I like the flower as well."
The name Rose is Rōhi in te reo Māori and the rose in Hird's painting sit behind her head like a halo.
She has also included a scotch thistle in the foreground which she says symbolises her Scottish heritage and is a nod to her grandmother, who came from Aberdeen.
Hird was one of a record number of young artists to submit her work to the open age art competition this year.
Rōhi, along with all the others winning works and finalists 2019 pattillo Whanganui Arts Review exhibition is showing at Sarjeant on the Quay until May 19.
