Founded over 50 years ago, St Matthew's Chamber Orchestra performs at St Matthew-In-The-City, Hobson Street in Auckland City, and is currently Auckland's longest established chamber orchestra. Beginning as a string group formed to accompany performances of Bach Cantatas, the orchestra has developed into a classical symphony orchestra performing a wide repertoire of music.

It is a non-profit cooperative made up of  musicians who all play for their love of music. Orchestra members also  contribute to all aspects of the Orchestra’s organisation.​Although  it is an amateur orchestra, St Matthew’s Chamber Orchestra rehearses  and performs like a professional one. It rehearses for just one week –  intensively – before each concert and rather than a resident conductor,  engages a different guest conductor for each concert. This provides  concertgoers with an exciting variety of orchestral music performed to a  very high standard in a dynamic venue.
