The result will incorporate arrangements of heritage classical music works and allows the orchestra to engage with cultural traditions as never seen before.
The original score has been commissioned by Orchestras Central and written by Stephen Small, who will also be guest music director for the project.
"A key aspect of the 'portability' of the Mass will be the potential for songs of local iwi to feature within its form," says Stephen.
"And there is even potential in the future to develop this in other languages and further grow connections with other cultures."
The Latin settings in the work incorporate arrangements of heritage classical music works. For example, the Credo is a setting of the Latin text with the Schubert Impromptu hidden in it.
"Lovers of traditional classical music will be just at home at this concert as those who enjoy the new and different," says Susan.
"This musical encounter will merge the sound of cultures colliding in striking harmony and we promise an unforgettable experience."
There's been a lot of excitement about this project already too.
"It's such a great opportunity to share the narrative of unity," says Michael Moore of Creative Waikato.
"And what better place to start that kōrero than from creation."
The concert is presented with support from Trust Waikato, WEL Energy Trust and Creative New Zealand.
