The four-panelled artwork was commissioned by Company Bay residents Stella and Donald Cullington, and was created by Maia artist Peter Mackenzie.
Mackenzie said Dame Kiri was the perfect choice for St Cecilia because she was a well-known New Zealander and she embodied the mix of cultures embraced by the Anglican Church of New Zealand.
Also captured in the window was the image of Anglican Diocese of Dunedin's Bishop the Right Reverend Dr Kelvin Wright, as St Paul.
Dame Kiri said her recital in Oamaru would be the last of 10 across New Zealand and Australia this month.
She will return to England tomorrow to prepare for more performances in Europe, and a guest appearance on the British period drama television series Downton Abbey, later this year.
She will play Australian soprano Dame Nellie Melba in the series, and will sing as part of her roll.
